Buy/Sell Volume Spike Radar

This indicator highlights unusual volume spikes and classifies them as buying pressure or selling pressure using price action context. It’s designed to spot when the crowd is stepping in aggressively — either on the bid (sell spikes) or on the ask (buy spikes).

How it works:

Compares current volume against a moving average of volume (default 50 bars).

A spike is flagged when volume is above the threshold (default = 2× vol MA).

Candle body position in its range determines direction:

Close near the top of the bar = Buy Spike.

Close near the bottom = Sell Spike.

Doji-like candles are filtered out using a minimum body % rule.

Visuals:

Background tint: teal for buy spikes, red for sell spikes.

Labels: optional tags on the chart showing “High BUY vol” or “High SELL vol”.

Histogram (lower pane): plots signed volume (positive = buy pressure, negative = sell pressure) with spikes emphasized.

Status table: shows live volume, moving average, and current spike status.

Use cases:

Spot institutional activity or panic selling.

Confirm breakouts or breakdowns with real buying/selling pressure.

Filter false moves by requiring both price + volume confirmation.
