Track swing structure. Every bar, it confirms a pivot high/low from SwingPeriod bars back (isPivotHigh/isPivotLow). These are the last significant swing points. Break of Structure (BOS) sets intent. A close above the last swing high = bullish BOS; a close below the last swing low = bearish BOS. This fixes the direction. Each swing can only trigger one BOS (shUsed/slUsed flags). Mark the POI = the origin of the impulse that caused the BOS. For a bullish BOS it looks back from the break bar to the swing low and marks two zone types: Order Block (OB): the last opposite-colour (bearish) candle before the up-move — its high/low become the zone. Fair-Value Gap (FVG): a 3-candle imbalance inside the impulse (candle k−1 high < candle k+1 low). The gap becomes the zone. Each zone stores its direction, origin bar, and a targetLevel = the extreme the impulse reached (the liquidity it was heading for). Bearish BOS is the mirror image. Entry on retrace. On later bars it scans active zones. When price trades back into a zone (bullish: c.Low <= z.high; bearish: c.High >= z.low), it fires an entry — CE at a bullish/demand POI, PE at a bearish/supply POI. If two sibling zones (OB + FVG) come from the same BOS, only the first one hit fires that bar (firedOrigin). Risk framing. Stop: just beyond the zone, buffered by SLBufferATR × ATR. Target: the impulse's targetLevel, capped at MaxRR. Qualified only if RR >= MinRR and the target is on the correct side of entry. Invalidation / expiry. A bullish zone dies if price closes below it (c.Close < z.low); bearish if it closes above. Zones also expire ExpiryBars after creation.
