ZigZagCore

ZigZagCore is a generic ZigZag engine that works with any user-defined threshold (ATR-based, volatility-based, fixed ticks, etc.).
API
zz_update(state, thr)
Parameters:
state (ZzState)
thr (float)
ZzState
Fields:
dir (series int)
highSinceLow (series float)
lowSinceHigh (series float)
lastHighLevel (series float)
lastLowLevel (series float)
lastHighIndex (series int)
lastLowIndex (series int)
highSinceLowIndex (series int)
lowSinceHighIndex (series int)
isNewHigh (series bool)
isNewLow (series bool)
Directional State
dir = 1 → market is in an upswing
dir = -1 → market is in a downswing
dir = na → initial undecided state
Live Swing Tracking (Unconfirmed Leg)
Continuously updated swing extremes:
highSinceLow — highest price since the last confirmed low
lowSinceHigh — lowest price since the last confirmed high
Their corresponding bar indices
These fields describe the current active swing leg, which updates every bar until a pivot is confirmed.
Pivot Detection
A pivot confirms only when price moves beyond the prior swing extreme by more than threshold. When this occurs, the library sets:
isNewHigh = true (on the detection bar only) and updates lastHighLevel, lastHighIndex
isNewLow = true and updates lastLowLevel, lastLowIndex
Added highBroken and lowBroken fields in ZzState
Updated:
ZzState
Fields:
dir (series int)
highSinceLow (series float)
lowSinceHigh (series float)
lastHighLevel (series float)
lastLowLevel (series float)
lastHighIndex (series int)
lastLowIndex (series int)
highSinceLowIndex (series int)
lowSinceHighIndex (series int)
isNewHigh (series bool)
isNewLow (series bool)
highBroken (series bool)
lowBroken (series bool)
-Stale bars: a direction switch will happen if a high/low has been standing and stale for N bars
-High/low break: a direction switch will be forced if a high/low is broken, despite the volatility threshold not being met
Both these changes are designed to improve stability in the face of rising and falling volatility measurements, while maintaining the direction switching rule (high must follow low, must follow high, etc.)
Updated:
zz_update(state, thr, staleBars)
Parameters:
state (ZzState)
thr (float)
staleBars (int)
Bugfix for stale bars logic to ensure correct pivot bar detection.
Refactor for handling stale bars and break logic together.
Updated:
zz_update(state, thr, staleBars, switchOnPriorLevelBreak)
Parameters:
