SMCNexusFactsCoreSMCNexusFactsCore is the confirmed, non-visual market-facts library for SMC Nexus by AreXoN. It provides bounded chart-timeframe facts for swing structure, BOS/CHoCH, MSS, FVG, Order Blocks, liquidity pools, sweeps, premium/discount and market context.
It contains no alerts, drawings, requests, transport, scoring or trade planning.
Contract version: 1.0.0. Libreria
FractalMemoryLib [Jayadev Rana]FractalMemoryLib packages the pattern-memory engine used by the Fractal Memory Projection indicator and the Fractal Memory Strategy so any script can import it.
WHAT IT DOES
The library finds the historical window whose movement shape most resembles the most recent bars (mean squared distance between stdev-normalized log returns), replays what followed that window as a projected close path, and sizes stops and targets adaptively by volatility regime.
EXPORTED FUNCTIONS
logRet(src) - one-bar log return of a series.
bestMatch(src, winLen, scanDepth, gapAhead) - scans up to scanDepth bars back and returns the offset of the most similar window plus a 0-100 similarity score. gapAhead reserves bars after the match for a projection.
analogPath(src, offset, fcLen, scaleF) - array of fcLen projected closes built by replaying the returns that followed the match, rescaled by scaleF (for example current ATR over ATR at the match).
adaptiveR(atrLen, rankLen, base) - volatility-adaptive unit risk: ATR times (base plus its 0-1 percentile rank), plus the rank itself. Call on every bar.
volRegime(volRank) - "Low", "Normal" or "High" label from the rank.
targets(entry, dirSign, unitR, slMult) - stop loss and TP1/TP2/TP3 at 1R, 2R and 3R.
USAGE NOTES
Call adaptiveR on every bar for ta consistency. bestMatch and analogPath are loop-heavy; for display purposes call them on the last bar only, and make sure the chart has at least scanDepth plus gapAhead bars of history. When the library itself is added to a chart it draws a small demo projection line from the best analog.
The analog projection is a statistical reference to a similar past episode, not a prediction, and not financial advice. Libreria

SMCNexusTradePlanCoreSMC Nexus Trade Plan Core is the public Trade Plan library used by SMC Nexus by AreXoN.
It provides deterministic candidate-plan resolution for Entry, direction-valid Stop Loss, real target candidates, bounded target clustering, Risk/Reward, Order Type, Confluence and final geometry validation.
All market structure, zones, liquidity levels, pivots and prices are supplied by the importing indicator. Targets are selected only from real caller-provided levels; the library does not fabricate prices.
This library produces analytical candidate-plan data only. It does not place or manage orders, connect to a broker, simulate fills or make performance claims. Libreria

ContextAwarenessEngineLibrary "ContextAwarenessEngine"
Shared "human contextual awareness" engine — structure memory,
zone memory, sequence engine, regime flags. Import this from any indicator
instead of rebuilding these primitives per-script (the bug pattern behind
Kurisko v1/v2's misfires: each indicator invents its own crude, unverified
context logic). FIRST DRAFT — verify every threshold before trusting it.
newStructureMemory(maxAgeBars, minMagnitudeATR)
Creates a new, empty structure memory.
Parameters:
maxAgeBars (int) : bars after which a pivot is forgotten
minMagnitudeATR (float) : minimum swing size (in ATR multiples) to be recorded — filters noise pivots
Returns: a fresh StructureMemory instance
prune(mem)
Prunes pivots older than maxAge. Call once per bar before recording.
Parameters:
mem (StructureMemory) : the StructureMemory to prune
recordWithMagnitude(mem, price, swingMagnitude, atrVal, isLow, touchTolATR)
Preferred entry point: caller supplies the actual swing magnitude
(e.g. abs(pivotPrice - priorOppositePivotPrice)) so "significant vs noise"
reflects real swing size, not just ATR at a point.
Parameters:
mem (StructureMemory) : the StructureMemory to update
price (float) : the pivot price
swingMagnitude (float) : the size of the swing this pivot represents (price units)
atrVal (float) : current ATR — swingMagnitude is measured in ATR multiples against this
isLow (bool) : true if this pivot is a swing LOW (directional override checks
for a genuinely lower low); false for a swing HIGH (checks for higher high).
Without this, a real break beyond an old level gets silently logged as a
mere "touch" of that level instead of a new, more extreme pivot — the exact
bug behind missing the deeper low in the circled BTCUSD chart area.
touchTolATR (float) : tolerance (x ATR) for counting a revisit vs a new pivot
Returns: — isNew true if recorded as a fresh pivot, matchedIndex is the array index touched (-1 if new)
currentExtreme(mem, wantLowest)
Returns the actual current floor/ceiling in memory — lowest low
or highest high still tracked — regardless of its ATR-relative magnitude
at formation. This answers "where is price's real extreme right now,"
which mostSignificant() (magnitude-ranked) does NOT answer.
Parameters:
mem (StructureMemory) : the StructureMemory to search
wantLowest (bool) : true to find the lowest price (support floor), false for highest (ceiling)
Returns: the most extreme Pivot by raw price, or na fields if empty
isStale(p, maxTouches)
A level touched too many times has likely already been consumed —
flag it as stale so callers stop treating it as fresh, reliable liquidity.
Parameters:
p (Pivot) : the Pivot to check
maxTouches (int) : touches beyond this count are considered stale
mostSignificant(mem, maxTouches)
The single most "significant" pivot still in memory — largest
magnitude among NON-STALE pivots (excludes levels already ground through
maxTouches times, since those have likely been consumed already). This is
the closest analogue to "the obvious swing point a human's eye lands on
first" — but a human also discounts a level they've watched fail three
times already, which is what the staleness filter encodes.
Parameters:
mem (StructureMemory) : the StructureMemory to search
maxTouches (int) : touches beyond this exclude a pivot as stale (see isStale)
Returns: the most significant non-stale Pivot, or na fields if none qualify
newZone(top, bottom, validBars, kind)
Creates a new zone.
Parameters:
top (float) : top of the zone
bottom (float) : bottom of the zone
validBars (int) : how many bars the zone stays "live" before expiring unfilled
kind (string) : free-text label for what kind of zone this is
Returns: a fresh Zone
isFresh(z)
Checks whether a zone is still within its validity window.
Parameters:
z (Zone) : the Zone to check
Returns: true if the zone hasn't expired
checkTouch(z, hi, lo)
Checks whether current price has entered the zone, and marks it
touched if so. Call once per bar for each active zone.
Parameters:
z (Zone) : the Zone to check/update
hi (float) : current bar high
lo (float) : current bar low
Returns: true if price is inside the zone on this bar
isActiveReaction(z)
A zone counts as an active, meaningful reaction target only if
it's still fresh AND has actually been touched — "sweep happened, price
came back" not just "gap exists somewhere in memory."
Parameters:
z (Zone) : the Zone to evaluate
entryPrice(z, aggressive)
Horner's two entry modes for an FVG zone: conservative waits for
the FULL gap fill and enters at the edge farthest into the zone (safer,
worse R:R, matches "wait for price to fill the entire gap" from her FVG
video); aggressive enters at the 50% midpoint/equilibrium (better R:R,
needs smaller size since it's a more precise level). Direction-aware via
z.kind so callers don't have to work out which edge is "far" themselves.
Parameters:
z (Zone) : the Zone to compute an entry for (kind must be "FVG_BULL" or "FVG_BEAR")
aggressive (bool) : true for the 50% midpoint entry, false for the far-edge conservative entry
Returns: the entry price, or na if z.kind isn't a recognized FVG type
stopPrice(z, atrVal, bufferATRmult)
The matching stop-loss reference: "beyond the far edge of the
FVG" per both Horner's video and this project's own Confluence Trading
Framework doc. A small ATR buffer is added so the stop isn't sitting
exactly on the boundary (which invites getting picked off by noise).
Parameters:
z (Zone) : the Zone to compute a stop for
atrVal (float) : current ATR, used for the buffer beyond the far edge
bufferATRmult (float) : how far beyond the far edge to place the stop (x ATR)
newSequence(maxBars)
Creates a new idle sequence tracker.
Parameters:
maxBars (int) : how many bars a sequence can sit at one stage before expiring
advance(seq, leg1, leg2, leg3)
Advances or resets a sequence given the state of its three legs.
Call once per bar with the three boolean conditions for THIS bar. Order is
enforced: leg2 only counts if stage is already >=1, leg3 only if stage is
already >=2 — mirrors bar_index-ordering without needing separate `>=` checks
at every call site.
Parameters:
seq (Sequence) : the Sequence to advance
leg1 (bool) : condition for stage 0->1 (e.g. liquidity sweep / zone touch)
leg2 (bool) : condition for stage 1->2 (e.g. extreme / momentum confirmation)
leg3 (bool) : condition for stage 2->3, i.e. the actual fire (e.g. divergence)
Returns: true on the exact bar the full sequence fires
describe(seq)
Human-readable status for a status-table row — this is the direct
answer to "why hasn't it fired yet," visible instead of a black-box boolean.
Parameters:
seq (Sequence) : the Sequence to describe
trendRegime(src)
Trend regime from price vs EMA200 + VWAP, as used across this project.
Parameters:
src (float) : typically `close`
Returns: "UP", "DOWN", or "NEUTRAL"
volRegime(atrVal, atrLookback)
Volatility regime relative to the instrument's own recent history —
avoids hardcoding an absolute number that only makes sense for one asset class.
Parameters:
atrVal (float) : current ATR
atrLookback (int) : bars to compare against for "normal" ATR
Returns: "HIGH", "LOW", or "NORMAL"

Arbor_Gradient_Boosting_GainzAlgoGainzAlgo is excited to bring the ability to perform gradient boosting and feature importance selection to Pine Script. Currently, there are no native capabilities within Pine Script for gradient boosting or feature importance selection. Arbor fills this significant gap by introducing a from-scratch Gradient Boosting Machine (GBM) engineered with XGBoost-style mechanics.
Designed to support both classification and regression tasks, and building on our Random Forest approach to Pinescript, Arbor utilizes depth-1 stumps, meaning it performs one split per round without column subsampling.
Because TradingView automatically lists the exported types and function parameters, the following outlines the core mechanics and capabilities you unlock by importing Arbor.
Core Mechanics
Arbor brings advanced machine-learning concepts directly into your Pine Script workflows:Advanced Training: Utilizes Newton leaf steps (second-order hessian weighting) and the exact XGBoost gain formula.
Regularization & Pruning: Integrates L2 regularization (lambda), minimum gain pruning (gamma), and minimum child weight checks to manage model complexity and prevent overfitting.
Stochasticity: Implements Fisher-Yates row subsampling to provide genuine round-to-round stochasticity matching XGBoost's subsample behavior.
Reproducibility: You can pass an optional seed to any fit function to ensure reproducible training runs across reloads.
Model Tiers
The library supports models scaled across three specific feature tiers:
GBM (1 Feature): Built for rapid classification or regression implementations.
GBM3 (3 Features): Purpose-built specifically for classification tasks.
GBM4 (4 Features): Supports both classification and regression, and uniquely offers XGBoost-style, gain-based feature importance evaluation.
Library "Arbor_Gradient_Boosting_GainzAlgo"
Arbor — gradient boosting for Pine Script. From-scratch GBM v2
with XGBoost-style mechanics: Fisher-Yates row subsampling, Newton leaf steps
(second-order hessian weighting), exact XGBoost gain formula with L2
regularization (lambda), minimum gain pruning (gamma), and minimum child
weight. Trees are depth-1 stumps (one split per round) and there is no
column (feature) subsampling — this is an XGBoost-style boosting scheme,
not a full XGBoost reimplementation. Supports classification and regression
across three feature tiers:
- GBM (1 feature) : gbm_fit / gbm_predict
classification or regression via is_classifier
- GBM3 (3 features) : gbm3_fit / gbm3_predict
classification only
- GBM4 (4 features) : gbm4_fit / gbm4_predict / gbm4_importance_pct
classification or regression with XGBoost-style
gain-based feature importance
All variants use Newton leaf steps, exact gain formula, L2 regularization,
Fisher-Yates shuffle subsampling, and gamma/min_child_weight pruning. Pass
an optional seed to any fit function for reproducible training runs.
gbm_fit(feat, target, n_rounds, lr, n_thresh, is_classifier, lambda, gamma, min_child_w, subsample, seed)
Fits a single-feature gradient-boosted stump ensemble using
XGBoost-style mechanics: Newton leaf steps (second-order hessian weighting),
exact gain formula with L2 regularization, gamma pruning, minimum child
weight, and Fisher-Yates row subsampling. Each round fits one depth-1 stump
(this is not a full multi-level tree, and there is no column subsampling).
Supports both binary classification (log-odds + sigmoid) and regression (MSE).
Parameters:

Isotropic Coordinate System (ICS)Library "ICS"
Isotropic Coordinate System (ICS): a dimensionless price-time space
for scale-invariant chart geometry.
Vertical axis: y = ln(price) / sigma, where sigma is the Yang-Zhang (2000)
minimum-variance, drift-independent, gap-consistent OHLC volatility estimator.
Horizontal axis: two scalings via the XScale enum.
legacy : x = bars / lookback. Linear window fraction. Backward compatible.
isotropic : x = sqrt(bars / lookback), with y additionally divided by
sqrt(lookback). Diffusion-consistent (sqrt-time scaling), so that
tan(theta) equals the z-score of the move and 45 degrees
corresponds to a move of exactly one standard deviation
of the n-bar log-return distribution. Assumes approximately
iid returns within the sigma window (the standard assumption
behind sqrt-time scaling; see Danielsson & Zigrand, 2006, for
its known limits under vol clustering and jumps).
Every output (angle, length, area, centroid) is a pure dimensionless number,
comparable across symbols, currencies, and timeframes.
Reference: Yang, D. & Zhang, Q. (2000), "Drift-Independent Volatility
Estimation Based on High, Low, Open, and Close Prices",
The Journal of Business, 73(3), 477-492.
yangZhangSigma(length)
Yang-Zhang volatility estimator. Minimum-variance, unbiased,
drift-independent, and consistent with opening gaps
(Yang & Zhang, 2000). Uses the unbiased sample variance
(biased = false) for both the overnight and open-to-close
components, matching the estimator's unbiasedness claim.
Parameters:
length (simple int) : (simple int) Rolling window length. Must be >= 2.
Returns: (series float) Per-bar sigma, floored at 1e-10.
toX(bars, lookback, mode)
Dimensionless horizontal coordinate.
Parameters:

Returns: (series float) Dimensionless y, or na when inputs are invalid.
moveZScore(dLogPrice, sigma, bars)
Z-score of a log-price move over n bars: dLog / (sigma * sqrt(n)).
In isotropic mode this equals tan(theta) of the same move.
Parameters:
dLogPrice (float) : (series float) ln(target) - ln(anchor).
sigma (float) : (series float) Per-bar Yang-Zhang sigma. Must be > 1e-10.
bars (int) : (series int) Number of bars in the move. Must be > 0.

On invalid inputs every field is set to na, so world X never
receives contaminated numbers.
Parameters:
td (TriangleData) : (TriangleData) Output object, updated in place.
anchorPrice (float) : (series float) Anchor price (world A). Must be > 0.
anchorBar (int) : (series int) Anchor bar_index.
targetPrice (float) : (series float) Target price (world A). Must be > 0.
targetBar (int) : (series int) Target bar_index. Must differ from anchorBar.
sig (float) : (series float) Yang-Zhang sigma. Must be > 1e-10.
lookback (int) : (series int) Horizontal unit window.
mode (series XScale) : (series XScale) Scaling mode.
Returns: (TriangleData) The same `td`, for chaining.
pinTriangle(td, anchorPrice, anchorBar, extremePrice, bodyPrice, curBar, sig, lookback, mode)
Pin (wick) triangle with three vertices in ICS space:
A = anchor, B = candle extreme, C = candle body edge.
Side BC is the wick. theta = signed angle at A between AB and AC.
Since xB = xC, the shoelace area reduces exactly to
0.5 * |yB - yC| * |dx|.
Parameters:
td (TriangleData) : (TriangleData) Output object, updated in place.
anchorPrice (float) : (series float) Anchor price (hh or ll). Must be > 0.
anchorBar (int) : (series int) Anchor bar_index.
extremePrice (float) : (series float) Candle extreme (high or low). Must be > 0.
bodyPrice (float) : (series float) Candle body edge. Must be > 0.
curBar (int) : (series int) Current bar_index. Must differ from anchorBar.
sig (float) : (series float) Yang-Zhang sigma. Must be > 1e-10.
lookback (int) : (series int) Horizontal unit window.
mode (series XScale) : (series XScale) Scaling mode.
Returns: (TriangleData) The same `td`, for chaining.
zeroTri(td)
Resets a TriangleData to na. Use when the structure is inactive,
so inactive periods never enter moving averages or normalization
as fake zero values.
Parameters:
td (TriangleData) : (TriangleData) Object to reset, updated in place.
Returns: (TriangleData) The same `td`, for chaining.
TriangleData
One triangle's measurements in ICS space. All fields dimensionless.
Fields:
theta (series float) : Signed hypotenuse angle in degrees; in isotropic mode tan(theta) is the z-score of the move.
dy (series float) : Signed Euclidean magnitude of the hypotenuse.
area (series float) : Triangle area (>= 0).
centroidY (series float) : Vertical centroid of the triangle.
FrozenAnchors
Anchors frozen at a reference bar, plus activity state.
Fields:
hh (series float) : Highest high at the freeze bar (world-A price units).
ll (series float) : Lowest low at the freeze bar (world-A price units).
mid (series float) : Geometric mean sqrt(hh * ll) at the freeze bar.
bar_x (series int) : bar_index of the freeze bar.
time_x (series int) : time of the freeze bar.
is_active (series bool) : Whether the frozen structure is currently active. Libreria
