Parabolic SAR Constraint Kinematics & Run Geometry
Overview
Parabolic SAR Constraint Kinematics & Run Geometry studies how a continuing Parabolic SAR step is formed and how the surrounding run develops. It keeps TradingView's ta.sar() as the plotted SAR series and adds measurements of the run's Extreme Point, remaining Arc, acceleration-factor progression, and prior-two-bar price constraint.
The central distinction is between the free parabolic candidate and the candidate after the two-bar constraint. The script measures how much movement the constraint removes, how much movement remains, and how frequently material constraints occur within a fully observed run. A synchronization check compares the reconstructed candidate with ta.sar() before exposing the related constraint percentages.
The PSAR formula itself is standard. The added functionality is the coordinated measurement of its step mechanics, run-relative geometry, observation completeness, and bounded run history. The indicator does not adapt the PSAR formula, filter its side changes, optimize parameters, or rank trading opportunities.
Chart layers
The default display contains the canonical SAR dots, an Extreme Point trace, a translucent SAR-to-Extreme-Point Arc, small side-change markers, yellow material-constraint halos, and a compact upper-right panel.
Cyan and pink distinguish the tracked SAR-below and SAR-above run states. Green and amber distinguish the corresponding Extreme Point traces. Colors and visibility are configurable. These colors describe tracked states; they do not prescribe an action.
The Extreme Point is the highest observed high in a SAR-below run or the lowest observed low in a SAR-above run. It is updated according to the selected confirmation setting.
Optional layers include the free candidate point, the constraint bridge, an Arc midline, the current run's origin line, descriptive event markers, and completed-run summaries. These additional layers are disabled by default to avoid crowding the chart. The bridge compares the free candidate with the plotted SAR on materially constrained bars after the synchronization check; the reconstructed guarded candidate can differ from the plotted SAR by the permitted tolerance.
Reading the compact panel
The default layout remains a three-row grid. Abbreviated captions and reduced spacing save horizontal space without changing the measurements or their numeric precision.
STATE: BELOW or ABOVE means the tracked SAR side relative to price. FULL means the run's beginning was observed; PARTIAL means tracking began during an existing run. TIGHT identifies the contracted-Arc state. SYNTHETIC identifies a non-standard chart.
RUN: An example such as "11b ✳3 ∥4" means 11 bars in the tracked run, three Extreme Point updates, and four bars since the last Extreme Point update. The star identifies updates; the parallel strokes identify elapsed bars without an update.
ARC: Current normalized SAR-to-Extreme-Point distance, followed by Arc Retention.
STEP: Absolute one-bar SAR movement, followed by that movement as a percentage of the remaining Arc. This percentage is a geometric ratio, not a return or probability; it is not capped at 100%.
MOTION: Mechanical state, TX percentage, observed AF, and synchronization symbol. TX means Step Transmission. For example, "FREE TX100.0% AF0.08" indicates an observed FREE state, transmission of 100.0% of the reconstructed free step, and an observed AF of 0.08.
CODE: The four-axis run signature and completed-run count. CODE is the compact label for the run signature, not a trading signal. The suffix n20 means 20 completed full runs are retained for the duration/brief-run history. When the signature display is disabled, HIST shows the sample count, average duration in bars, and brief-run share instead.
Hovering over the cells reveals definitions, the processing scope, reconstruction error, constraint percentages, recent recorded signature states, and rolling history summaries. The panel shows the latest execution state; moving the cursor over an older bar does not make the panel display that bar's historical state. Extended Data Window output can be enabled for historical numeric inspection inside the research window.
Arc and distance units
Arc = abs(Current SAR - Tracked Extreme Point)
Arc Retention = 100 x Current Arc / Widest Arc recorded in the same tracked run
A lower retention value means the current Arc is narrower relative to that run's widest recorded Arc. It does not establish that a price reversal is approaching.
Distance units are selectable: ATR at run start, percent from run origin, minimum ticks, or raw price. The ATR-style normalizer smooths true range using RMA, SMA, EMA, or WMA. The range used for normalization is captured when tracking of the run begins, and percent distances use the absolute close captured as the run origin. In a PARTIAL run, these references belong to the first tracked bar, not the unknown actual beginning of the run.
Normalization and optional marker spacing do not alter the canonical SAR calculation.
Tight Arc and re-expansion
After the configured minimum run age, TIGHT is entered when Arc Retention is at or below the selected contraction threshold. Defaults are five bars and 35% retention.
The contracted state is released only after a new Extreme Point appears and retention reaches the contraction threshold plus the selected hysteresis, capped at 100%. Default hysteresis is 20 percentage points, giving a default release level of 55%.
The two thresholds reduce repeated state changes near a single boundary. TIGHT is a latched run state, so a retention value above the entry threshold does not by itself end that state. Neither contraction nor re-expansion forecasts a future market event.
Observed acceleration factor
Observed AF = min(Starting AF + Recorded EP Updates x AF Increment, Effective Maximum AF)
AF Progress = 100 x (Observed AF - Starting AF) / (Effective Maximum AF - Starting AF)
Defaults are 0.02 for the starting factor, 0.02 for the increment, and 0.20 for the maximum. If the entered maximum is below the starting factor, the effective maximum is raised to the starting factor. When both are equal, AF progress is represented as 100%.
The observed AF is reconstructed from the tracked Extreme Point sequence. It is not an independently exposed internal AF series supplied by ta.sar(). Partial-run values do not recover unobserved pre-window updates.
Free candidate and two-bar constraint
The reconstruction is attempted on eligible continuing bars of FULL runs, with the required prior values available and the current raw SAR side agreeing with the tracked run.
Free Candidate = Previous SAR + Previous Observed AF x (Previous Tracked EP - Previous SAR)
For a SAR-below run:
Guarded Candidate = min(Free Candidate, Previous Low, Low Two Bars Ago)
For a SAR-above run:
Guarded Candidate = max(Free Candidate, Previous High, High Two Bars Ago)
The resulting guarded candidate is compared with the current ta.sar() value. The default permitted difference is two minimum ticks; the tolerance is adjustable and includes a small numerical floor.
If the reconstruction is outside tolerance, the state becomes CHECK and Constraint Load and TX are unavailable. If the bar is not eligible, the state is INIT. A successful check establishes agreement within the selected tolerance on that bar, not exact recovery of every internal PSAR state or independent validation of the model.
Constraint Load and Step Transmission
Free Step = abs(Free Candidate - Previous SAR)
Removed Distance = abs(Free Candidate - Guarded Candidate)
Constraint Load = 100 x Removed Distance / Free Step
TX measures the guarded directional step as a percentage of the free directional step. Direction here means the mechanical direction of the tracked PSAR run, not a proposed trade.
TX = 100 x Guarded Directional Step / Free Directional Step
The displayed constraint percentages require synchronization and a valid positive denominator. They are bounded between 0% and 100%. In ordinary eligible cases, they describe the removed and transmitted portions of the reconstructed step. A zero or invalid denominator produces unavailable data rather than an invented percentage.
A measurable constraint requires both a removed distance of at least one quarter of a minimum tick and Constraint Load of at least 1%. A material constraint additionally requires the user-selected materiality threshold, which defaults to 12.5%.
MOTION states and symbols
INIT: The current bar is not eligible for the continuing-run reconstruction, including during partial tracking or at the start of a run.
CHECK: The guarded candidate differs from ta.sar() by more than the permitted tolerance.
FREE: The measurable-constraint conditions are not satisfied. This includes effects below the residual or load thresholds, not necessarily a mathematically exact zero effect.
TRACE: A measurable constraint exists, but its load is below the materiality threshold.
BRAKE: A material constraint exists and the guarded directional step remains greater than one quarter of a minimum tick.
PINNED: A material constraint exists and the guarded directional step is at or below that quarter-tick threshold.
The check mark means agreement within tolerance; the exclamation mark means outside tolerance; the ellipsis means not yet eligible. None is a confidence rating or market recommendation.
Yellow halos and run occupancy
A yellow halo identifies a bar meeting the synchronized material-constraint conditions. It marks a mechanical effect on the PSAR step, not an entry, exit, reversal prediction, target, or stop.
Run Constraint Occupancy = 100 x Materially Constrained Counted Bars / Synchronized Counted Bars
The counts follow the selected confirmation setting and exclude the side-change bar. Under the default setting, they are committed at bar close. The percentage measures how frequently the guardrail materially affected the eligible observations in that run, not the probability of a future outcome.
Run signature: A, F, P, C
An example code is A3·F2·P2·C0.
A is Arc Retention.
F is observed AF Progress.
P is Extreme-Point Pause Share: 100 x Bars Since Latest EP / (Run Age - 1), with zero used at age one.
C is current Constraint Load.
A, F, and P use four fixed percentage bands:
1: below 25%
2: 25% to below 50%
3: 50% to below 75%
4: 75% or higher
C uses:
C0: valid load below 1%
C1: 1% to below 25%
C2: 25% to below 50%
C3: 50% to below 75%
C4: 75% or higher
C-: Constraint Load is unavailable
C- can occur because the bar is ineligible, synchronization fails, or the denominator is invalid. When no complete signature can be formed, placeholder bands are shown. C is based on the numeric load, whereas MOTION also applies the quarter-tick residual test and the selected materiality threshold; the two displays need not change together.
A3·F2·P2·C0 therefore describes retention from 50% to below 75%, AF progress from 25% to below 50%, pause share from 25% to below 50%, and valid constraint load below 1%.
These are fixed ranges, not sample quartiles, learned regimes, rankings, or probabilities. The code helps compare similarly structured observations without implying similar future outcomes. Up to three recent distinct synchronized signature observations are available in the tooltip; this is not an automatic historical pattern search.
FULL, PARTIAL, and completed-run history
A FULL run begins at an observed SAR side change inside the research window. A PARTIAL run was already underway when tracking began. Only completed FULL runs enter the rolling history.
The memory setting defaults to 20 and accepts 3 to 100 runs. Duration and brief-run history retain the latest completed full runs. The brief threshold defaults to four bars or fewer.
Constraint-occupancy history accepts only completed full runs with a valid occupancy value. Runs without that value are skipped for this particular average, so its sample can differ from the duration/brief-run sample.
Optional completed-run labels also show EP updates, time at the maximum observed AF stage, constraint occupancy, and tight-Arc episode count. These summaries describe completed observations, not simulated transactions.
Research window and runtime
Recent bars is the default scope. The custom research window defaults to 3,000 bars and can be set from 500 to 50,000. All available bars removes that custom limit, subject to the history available on the chart.
The boundary is fixed when the script loads or recalculates. Subsequent realtime bars are included; the window is not a continuously sliding hard cap. Reloading or changing an input rebuilds it.
Before the boundary, canonical ta.sar() and the selected normalizer still evaluate to provide continuous underlying series. The window limits custom run analysis, reconstruction, history, events, and plotted research output; it is not Pine's native calc_bars_count restriction and does not prevent every underlying calculation from running on earlier bars.
Larger windows and All available bars can increase runtime. Use a smaller window if a runtime warning occurs. This is a research and resource setting, not an access restriction.
Controls and alerts
Users can change the research scope, PSAR factors, confirmation behavior, normalization, history length, constraint threshold, synchronization tolerance, visual layers, marker limits, panel layout and position, right-edge clearance, text size, bold formatting, and colors.
Alerts are disabled by default. Available conditions report a SAR side change, Arc contraction, Arc re-expansion, the onset of a material constraint, an age milestone, the observed AF maximum, an EP pause, or completion of a brief full run. They do not specify trading actions.
Extended Data Window output is also disabled by default. Enabling it exposes additional numeric series without changing the underlying measurement rules.
Suggested research workflow
Start on a standard candlestick or bar chart with default settings. Identify the SAR dots, Extreme Point trace, and Arc before reading the panel. Check FULL or PARTIAL, inspect ARC and STEP, and then use MOTION and its tooltip to examine the reconstructed constraint.
For a worked mechanical example, a free directional step of ten ticks reduced to six ticks has a four-tick removed distance: Constraint Load is 40% and TX is 60%, provided the guarded candidate synchronizes and the other eligibility conditions hold. This example explains the arithmetic; it does not describe a trading result.
Use CODE to compare descriptive states, or enable the candidate point and bridge for closer mechanical inspection. Keep the symbol, timeframe, PSAR factors, distance unit, and observation policy consistent when comparing records.
Realtime behavior and limitations
Confirm state changes at bar close is enabled by default. Run changes, EP updates, descriptive event records, and history counters are committed under that setting. The active ta.sar() point, current geometry, constraint calculations, halos, and current displayed signature can nevertheless change before the bar closes. The panel can retain a committed run state while live geometric values update. Disabling confirmation allows more provisional intrabar behavior.
The script is not described as completely non-repainting. Use closed bars for reproducible comparisons.
Non-standard chart types supply synthetic or transformed OHLC. The panel marks them as SYNTHETIC; their measurements describe that generated chart series, not standard market bars.
PSAR can change sides frequently in irregular or sideways markets. A synchronized reconstruction is only a numerical consistency check within tolerance. Changing the available history, research boundary, settings, or timeframe can change the tracked run statistics. Extreme parameter values may produce more unavailable or CHECK observations. Defaults are general research settings, not optimized values.
This open-source indicator is a descriptive visualization and numerical research tool. It makes no claims about forecast accuracy, trading performance, or a predictive edge, and it does not provide individualized recommendations or trading instructions.
Parabolic SAR Constraint Kinematics & Run Geometry studies how a continuing Parabolic SAR step is formed and how the surrounding run develops. It keeps TradingView's ta.sar() as the plotted SAR series and adds measurements of the run's Extreme Point, remaining Arc, acceleration-factor progression, and prior-two-bar price constraint.
The central distinction is between the free parabolic candidate and the candidate after the two-bar constraint. The script measures how much movement the constraint removes, how much movement remains, and how frequently material constraints occur within a fully observed run. A synchronization check compares the reconstructed candidate with ta.sar() before exposing the related constraint percentages.
The PSAR formula itself is standard. The added functionality is the coordinated measurement of its step mechanics, run-relative geometry, observation completeness, and bounded run history. The indicator does not adapt the PSAR formula, filter its side changes, optimize parameters, or rank trading opportunities.
Chart layers
The default display contains the canonical SAR dots, an Extreme Point trace, a translucent SAR-to-Extreme-Point Arc, small side-change markers, yellow material-constraint halos, and a compact upper-right panel.
Cyan and pink distinguish the tracked SAR-below and SAR-above run states. Green and amber distinguish the corresponding Extreme Point traces. Colors and visibility are configurable. These colors describe tracked states; they do not prescribe an action.
The Extreme Point is the highest observed high in a SAR-below run or the lowest observed low in a SAR-above run. It is updated according to the selected confirmation setting.
Optional layers include the free candidate point, the constraint bridge, an Arc midline, the current run's origin line, descriptive event markers, and completed-run summaries. These additional layers are disabled by default to avoid crowding the chart. The bridge compares the free candidate with the plotted SAR on materially constrained bars after the synchronization check; the reconstructed guarded candidate can differ from the plotted SAR by the permitted tolerance.
Reading the compact panel
The default layout remains a three-row grid. Abbreviated captions and reduced spacing save horizontal space without changing the measurements or their numeric precision.
STATE: BELOW or ABOVE means the tracked SAR side relative to price. FULL means the run's beginning was observed; PARTIAL means tracking began during an existing run. TIGHT identifies the contracted-Arc state. SYNTHETIC identifies a non-standard chart.
RUN: An example such as "11b ✳3 ∥4" means 11 bars in the tracked run, three Extreme Point updates, and four bars since the last Extreme Point update. The star identifies updates; the parallel strokes identify elapsed bars without an update.
ARC: Current normalized SAR-to-Extreme-Point distance, followed by Arc Retention.
STEP: Absolute one-bar SAR movement, followed by that movement as a percentage of the remaining Arc. This percentage is a geometric ratio, not a return or probability; it is not capped at 100%.
MOTION: Mechanical state, TX percentage, observed AF, and synchronization symbol. TX means Step Transmission. For example, "FREE TX100.0% AF0.08" indicates an observed FREE state, transmission of 100.0% of the reconstructed free step, and an observed AF of 0.08.
CODE: The four-axis run signature and completed-run count. CODE is the compact label for the run signature, not a trading signal. The suffix n20 means 20 completed full runs are retained for the duration/brief-run history. When the signature display is disabled, HIST shows the sample count, average duration in bars, and brief-run share instead.
Hovering over the cells reveals definitions, the processing scope, reconstruction error, constraint percentages, recent recorded signature states, and rolling history summaries. The panel shows the latest execution state; moving the cursor over an older bar does not make the panel display that bar's historical state. Extended Data Window output can be enabled for historical numeric inspection inside the research window.
Arc and distance units
Arc = abs(Current SAR - Tracked Extreme Point)
Arc Retention = 100 x Current Arc / Widest Arc recorded in the same tracked run
A lower retention value means the current Arc is narrower relative to that run's widest recorded Arc. It does not establish that a price reversal is approaching.
Distance units are selectable: ATR at run start, percent from run origin, minimum ticks, or raw price. The ATR-style normalizer smooths true range using RMA, SMA, EMA, or WMA. The range used for normalization is captured when tracking of the run begins, and percent distances use the absolute close captured as the run origin. In a PARTIAL run, these references belong to the first tracked bar, not the unknown actual beginning of the run.
Normalization and optional marker spacing do not alter the canonical SAR calculation.
Tight Arc and re-expansion
After the configured minimum run age, TIGHT is entered when Arc Retention is at or below the selected contraction threshold. Defaults are five bars and 35% retention.
The contracted state is released only after a new Extreme Point appears and retention reaches the contraction threshold plus the selected hysteresis, capped at 100%. Default hysteresis is 20 percentage points, giving a default release level of 55%.
The two thresholds reduce repeated state changes near a single boundary. TIGHT is a latched run state, so a retention value above the entry threshold does not by itself end that state. Neither contraction nor re-expansion forecasts a future market event.
Observed acceleration factor
Observed AF = min(Starting AF + Recorded EP Updates x AF Increment, Effective Maximum AF)
AF Progress = 100 x (Observed AF - Starting AF) / (Effective Maximum AF - Starting AF)
Defaults are 0.02 for the starting factor, 0.02 for the increment, and 0.20 for the maximum. If the entered maximum is below the starting factor, the effective maximum is raised to the starting factor. When both are equal, AF progress is represented as 100%.
The observed AF is reconstructed from the tracked Extreme Point sequence. It is not an independently exposed internal AF series supplied by ta.sar(). Partial-run values do not recover unobserved pre-window updates.
Free candidate and two-bar constraint
The reconstruction is attempted on eligible continuing bars of FULL runs, with the required prior values available and the current raw SAR side agreeing with the tracked run.
Free Candidate = Previous SAR + Previous Observed AF x (Previous Tracked EP - Previous SAR)
For a SAR-below run:
Guarded Candidate = min(Free Candidate, Previous Low, Low Two Bars Ago)
For a SAR-above run:
Guarded Candidate = max(Free Candidate, Previous High, High Two Bars Ago)
The resulting guarded candidate is compared with the current ta.sar() value. The default permitted difference is two minimum ticks; the tolerance is adjustable and includes a small numerical floor.
If the reconstruction is outside tolerance, the state becomes CHECK and Constraint Load and TX are unavailable. If the bar is not eligible, the state is INIT. A successful check establishes agreement within the selected tolerance on that bar, not exact recovery of every internal PSAR state or independent validation of the model.
Constraint Load and Step Transmission
Free Step = abs(Free Candidate - Previous SAR)
Removed Distance = abs(Free Candidate - Guarded Candidate)
Constraint Load = 100 x Removed Distance / Free Step
TX measures the guarded directional step as a percentage of the free directional step. Direction here means the mechanical direction of the tracked PSAR run, not a proposed trade.
TX = 100 x Guarded Directional Step / Free Directional Step
The displayed constraint percentages require synchronization and a valid positive denominator. They are bounded between 0% and 100%. In ordinary eligible cases, they describe the removed and transmitted portions of the reconstructed step. A zero or invalid denominator produces unavailable data rather than an invented percentage.
A measurable constraint requires both a removed distance of at least one quarter of a minimum tick and Constraint Load of at least 1%. A material constraint additionally requires the user-selected materiality threshold, which defaults to 12.5%.
MOTION states and symbols
INIT: The current bar is not eligible for the continuing-run reconstruction, including during partial tracking or at the start of a run.
CHECK: The guarded candidate differs from ta.sar() by more than the permitted tolerance.
FREE: The measurable-constraint conditions are not satisfied. This includes effects below the residual or load thresholds, not necessarily a mathematically exact zero effect.
TRACE: A measurable constraint exists, but its load is below the materiality threshold.
BRAKE: A material constraint exists and the guarded directional step remains greater than one quarter of a minimum tick.
PINNED: A material constraint exists and the guarded directional step is at or below that quarter-tick threshold.
The check mark means agreement within tolerance; the exclamation mark means outside tolerance; the ellipsis means not yet eligible. None is a confidence rating or market recommendation.
Yellow halos and run occupancy
A yellow halo identifies a bar meeting the synchronized material-constraint conditions. It marks a mechanical effect on the PSAR step, not an entry, exit, reversal prediction, target, or stop.
Run Constraint Occupancy = 100 x Materially Constrained Counted Bars / Synchronized Counted Bars
The counts follow the selected confirmation setting and exclude the side-change bar. Under the default setting, they are committed at bar close. The percentage measures how frequently the guardrail materially affected the eligible observations in that run, not the probability of a future outcome.
Run signature: A, F, P, C
An example code is A3·F2·P2·C0.
A is Arc Retention.
F is observed AF Progress.
P is Extreme-Point Pause Share: 100 x Bars Since Latest EP / (Run Age - 1), with zero used at age one.
C is current Constraint Load.
A, F, and P use four fixed percentage bands:
1: below 25%
2: 25% to below 50%
3: 50% to below 75%
4: 75% or higher
C uses:
C0: valid load below 1%
C1: 1% to below 25%
C2: 25% to below 50%
C3: 50% to below 75%
C4: 75% or higher
C-: Constraint Load is unavailable
C- can occur because the bar is ineligible, synchronization fails, or the denominator is invalid. When no complete signature can be formed, placeholder bands are shown. C is based on the numeric load, whereas MOTION also applies the quarter-tick residual test and the selected materiality threshold; the two displays need not change together.
A3·F2·P2·C0 therefore describes retention from 50% to below 75%, AF progress from 25% to below 50%, pause share from 25% to below 50%, and valid constraint load below 1%.
These are fixed ranges, not sample quartiles, learned regimes, rankings, or probabilities. The code helps compare similarly structured observations without implying similar future outcomes. Up to three recent distinct synchronized signature observations are available in the tooltip; this is not an automatic historical pattern search.
FULL, PARTIAL, and completed-run history
A FULL run begins at an observed SAR side change inside the research window. A PARTIAL run was already underway when tracking began. Only completed FULL runs enter the rolling history.
The memory setting defaults to 20 and accepts 3 to 100 runs. Duration and brief-run history retain the latest completed full runs. The brief threshold defaults to four bars or fewer.
Constraint-occupancy history accepts only completed full runs with a valid occupancy value. Runs without that value are skipped for this particular average, so its sample can differ from the duration/brief-run sample.
Optional completed-run labels also show EP updates, time at the maximum observed AF stage, constraint occupancy, and tight-Arc episode count. These summaries describe completed observations, not simulated transactions.
Research window and runtime
Recent bars is the default scope. The custom research window defaults to 3,000 bars and can be set from 500 to 50,000. All available bars removes that custom limit, subject to the history available on the chart.
The boundary is fixed when the script loads or recalculates. Subsequent realtime bars are included; the window is not a continuously sliding hard cap. Reloading or changing an input rebuilds it.
Before the boundary, canonical ta.sar() and the selected normalizer still evaluate to provide continuous underlying series. The window limits custom run analysis, reconstruction, history, events, and plotted research output; it is not Pine's native calc_bars_count restriction and does not prevent every underlying calculation from running on earlier bars.
Larger windows and All available bars can increase runtime. Use a smaller window if a runtime warning occurs. This is a research and resource setting, not an access restriction.
Controls and alerts
Users can change the research scope, PSAR factors, confirmation behavior, normalization, history length, constraint threshold, synchronization tolerance, visual layers, marker limits, panel layout and position, right-edge clearance, text size, bold formatting, and colors.
Alerts are disabled by default. Available conditions report a SAR side change, Arc contraction, Arc re-expansion, the onset of a material constraint, an age milestone, the observed AF maximum, an EP pause, or completion of a brief full run. They do not specify trading actions.
Extended Data Window output is also disabled by default. Enabling it exposes additional numeric series without changing the underlying measurement rules.
Suggested research workflow
Start on a standard candlestick or bar chart with default settings. Identify the SAR dots, Extreme Point trace, and Arc before reading the panel. Check FULL or PARTIAL, inspect ARC and STEP, and then use MOTION and its tooltip to examine the reconstructed constraint.
For a worked mechanical example, a free directional step of ten ticks reduced to six ticks has a four-tick removed distance: Constraint Load is 40% and TX is 60%, provided the guarded candidate synchronizes and the other eligibility conditions hold. This example explains the arithmetic; it does not describe a trading result.
Use CODE to compare descriptive states, or enable the candidate point and bridge for closer mechanical inspection. Keep the symbol, timeframe, PSAR factors, distance unit, and observation policy consistent when comparing records.
Realtime behavior and limitations
Confirm state changes at bar close is enabled by default. Run changes, EP updates, descriptive event records, and history counters are committed under that setting. The active ta.sar() point, current geometry, constraint calculations, halos, and current displayed signature can nevertheless change before the bar closes. The panel can retain a committed run state while live geometric values update. Disabling confirmation allows more provisional intrabar behavior.
The script is not described as completely non-repainting. Use closed bars for reproducible comparisons.
Non-standard chart types supply synthetic or transformed OHLC. The panel marks them as SYNTHETIC; their measurements describe that generated chart series, not standard market bars.
PSAR can change sides frequently in irregular or sideways markets. A synchronized reconstruction is only a numerical consistency check within tolerance. Changing the available history, research boundary, settings, or timeframe can change the tracked run statistics. Extreme parameter values may produce more unavailable or CHECK observations. Defaults are general research settings, not optimized values.
