Long-short energy ratio /多空能量比值

This indicator calculates the relative strength of bulls and bears by measuring the average candle body movement within a user-defined window (default: 50 bars).

Bull Energy = average percentage change of all bullish candles in the lookback period

Bear Energy = average percentage change of all bearish candles in the lookback period

Energy Ratio = Bull Energy ÷ Bear Energy

The ratio is plotted as a curve around the baseline of 1:

Ratio > 1 → Bull side shows stronger momentum

Ratio < 1 → Bear side shows stronger momentum

Ratio ≈ 1 → Balanced market conditions

This tool helps visualize short-term shifts in buying and selling pressure, offering a simple mean-reversion perspective or a confirmation of trend strength depending on the context.
