Volume-Based Supply & Demand Zones

Most supply and demand indicators just draw boxes on the chart and call it a day. Volume-Based Supply & Demand Zones goes deeper. Every zone is built from real pivot structure, and inside each zone you see the actual battle between buyers and sellers, calculated using intrabar delta, not a simple green candle/red candle guess.

The volume bars inside each zone show buying pressure versus selling pressure using a delta-weighted formula. Instead of assigning 100% of a candle's volume to one side based on color, the indicator measures where price closed relative to its range. A candle that closed near its high distributes most of its volume to buyers, even if it opened red. This gives you an honest read on who is in control at that price level.

Zones are sized dynamically with ATR so they reflect actual volatility, and a merge algorithm combines overlapping levels into single clean zones instead of cluttering your chart.

Key Features

• Delta-weighted volume analysis. Each zone displays real buying and selling pressure using intrabar price position, not candle color. You see who actually controls the level.

• 3D gradient volume bars. Buyer and seller strength rendered as layered gradient bars inside each zone. Dominant side is immediately visible at a glance.

• Two volume modes. Pivot Bar mode shows volume at the formation candle only. Cumulative mode aggregates every bar that has touched the zone since it formed, giving you a running pressure score.

• ATR-sized zones. Zone width adapts to current volatility automatically. No fixed widths, no manual adjustment needed.

• Smart zone merging. Overlapping zones at similar price levels merge into a single clean zone instead of stacking on top of each other.

• Confirmed breakout signals. One signal per zone, fires only on a confirmed close beyond the buffer boundary. No repeated alerts, no noise.

• Dynamic role flip. When price breaks through a supply zone it becomes demand, and vice versa. The chart always shows current structure.

  
  

How To Use It

Add the indicator and select Balanced or Swing detection mode. Watch the volume bars inside each zone. If the green bar dominates a demand zone, buyers are holding that level with conviction. If the red bar is growing, the zone is weakening and a breakdown is more likely. When a breakout signal fires, the level has flipped and you should treat it as the opposite role. Set alerts on breakout conditions so you catch structural shifts without watching the chart.
