TSI SuperTrend Decision Strategy

Combines a correlation-based Trend Strength Index with SuperTrend direction. Long trades are taken when the SuperTrend is bullish and TSI is above -threshold. Short trades are taken when the SuperTrend is bearish and TSI is below +threshold. Optional take profit and stop loss can be enabled.

  • Indicators: Correlation, SuperTrend
