Matt Market Efficiency

This is a custom Pine Script v5 indicator for TradingView that creates a Market Efficiency Heatmap as a background overlay on your chart. It visualizes how "efficient" the market's price movement is over a specified period—essentially measuring how much of the total price volatility (wiggle room) resulted in net directional progress, weighted with volume activity.
High efficiency (stronger, less transparent color) indicates a clean trend with minimal wasted movement (e.g., a strong uptrend or downtrend).
Low efficiency (fainter color) suggests choppy, inefficient price action (e.g., ranging or noisy market).
Color coding: Teal for bullish (net price up), Purple for bearish (net price down).
The heatmap intensity scales from 1% opacity (very low efficiency) to 25% opacity (high efficiency), making it subtle yet informative without overwhelming the chart.
