Volume Scanner (Spikes & Drops) [Context]

💡 In many trading strategies, volume is used as a filter — but not all volume matters.
What really counts are moments when volume suddenly spikes or drops — these are the bars where something important might be happening: a large player enters the market, a fakeout occurs, or a trend shift begins.

🎯 What this indicator does:
This script highlights only the most significant volume anomalies, filtering out the noise and focusing on real movement:

🔺 Green background = Volume Spike (sudden increase)

🔻 Red background = Volume Drop (sudden decrease)

📊 Optional contextual filter:

Enable price context to show signals only when volume shifts occur alongside a breakout of recent high/low.

Fully customizable: control the strength of spikes/drops, the lookback period, and the minimum gap between signals.

📦 Great for:

Adding a clean volume filter to price action strategies

Quickly spotting key volume bars in real time

Works on any timeframe and market (crypto, forex, stocks, indices)
