Mirrored Buy/Sell Volume + Cumulative Delta

User Guide: Mirrored Buy/Sell Volume (Histogram)
🔍 What It Does
Displays green bars above zero for estimated buy volume
Displays red bars below zero for estimated sell volume
Adds a blue line showing Cumulative Delta (buy − sell over time)
Optional threshold lines help spot when net momentum builds up


📊 How Volume is Estimated
Same estimation method as the table version:
Buy Volume is proportion of volume estimated using (close - low) / (high - low)

Sell Volume is remainder of the total volume
Cumulative Delta = running total of (Buy − Sell) volume


This gives you:
A real-time sense of which side is gradually gaining control
More context than looking at candles or volume bars alone


✅ Best For
Visual trade decision support: who’s winning the tug-of-war?
Spotting trend initiation or momentum shifts
Combining with oscillator/trend tools for confirmation


⚠️ Limitations
Still an approximation — not based on actual trade aggressor data
Cannot separate passive vs. aggressive orders
Cumulative Delta does not reset unless specifically coded to do so
May mislead if the bar has long wicks or closes near midpoint
