Source Code

Overview

USI Flip Strategy enters long or short positions when fast lines cross slow lines, filtered by volume ratio thresholds, trend alignment, and stack order rules. Exits occur via fast EMA crosses, opposing USI flips, or ATR impulse threshold breaches. Users can select timeframe presets, adjust line lengths, and configure exit conditions. The strategy plots trade labels and background state fills, but features no default stop loss.

Multi-length USI RSI line crossover logic
Volume ratio and trend stack filters
Multiple exit conditions including EMA and ATR impulse
Presets for multiple trading timeframes

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
