FVG Zones – shrink on fill (bull/bear)

Detects classic 3-candle FVGs (ICT definition).
Draws zones as boxes that extend to the right.
On each bar close:
Checks overlap with the current candle.
Shrinks the zone when price wicks into it (bullish: top moves down; bearish: bottom moves up).
Deletes the zone once it’s completely filled/closed.
Inputs: bullish/bearish zone color, border color, and max number of visible FVGs.
Possible extensions:
Multi-timeframe FVGs (e.g. H1 FVGs shown on M5).
Separate limits for bullish and bearish zones.
Alerts for new FVG, partial fill, or closed FVG.
Option “Body only” (ignore wicks when detecting overlap).
Minimum FVG size filter (ticks/ATR).
