Volume Buy/Sell Split

Visually decompose each bar’s total volume into estimated “buy” and “sell” components, so you can instantly see which side—buyers or sellers—dominated on each candle.
Key Features
Total Volume Base
A solid grey histogram shows the absolute volume on every bar.
Buy vs. Sell Split
Buying Volume is calculated as
```volume × (close – low) / (high – low)```
Selling Volume is calculated as
```volume × (high – close) / (high – low)```
These estimates assume that when price closes near the high, more of that bar’s volume was “aggressive buying,” and vice versa.
Dynamic Stacking
The larger of the two components (buying vs. selling) is plotted directly on top of the grey base, in blue (if buying dominates) or yellow (if selling dominates).
The smaller component is plotted above that, in the complementary color, so the full column still represents total volume.
30‑Bar Average Marker
A thin purple line appears at the 30‑bar simple moving average of volume—but only on bars where volume exceeds that average—helping you spot volume spikes at a glance.
How to Interpret
Tall grey columns = high total volume bars.
Blue‑tinted sections = buying pressure; yellow‑tinted sections = selling pressure.
When the blue (buy) portion is larger, buyers had the upper hand; a larger yellow portion indicates sellers dominated.
Purple markers highlight bars where volume is above its 30‑period average, drawing your eye to unusually active sessions.
Usage Notes
Overlay: false (panel below price)
No external inputs to adjust—plug and play.
Ideal for spotting divergences between price and volume aggression, confirming breakouts, or identifying potential exhaustion moves when one side’s volume spikes.
Add this script to your charts to gain clear, color‑coded insights into buying vs. selling activity on every candle.
