RSI Trader V1 Strategy

This strategy uses the Relative Strength Index (RSI) to identify reversals after short-term extremes. A buy signal occurs when RSI crosses above the oversold threshold after staying below it for two consecutive candles. A sell signal occurs when RSI crosses below the overbought threshold after staying above it for two candles. The strategy optionally closes an existing opposite position and trades only within a configurable time window.

Details

  • Entry Criteria:
    • Long: RSI > BuyPoint and RSI for the previous two candles < BuyPoint.
    • Short: RSI < SellPoint and RSI for the previous two candles > SellPoint.
  • Exit Criteria: Opposite signal or protective stop/take-profit.
  • Time Filter: Trades only when the candle's opening hour is between StartHour and EndHour.
  • Stops: Fixed take profit and stop loss expressed in price units.
  • Parameters:
    • RsiPeriod – RSI calculation period.
    • BuyPoint – oversold level for long entries.
    • SellPoint – overbought level for short entries.
    • CloseOnOpposite – close current position when opposite signal appears.
    • StartHour / EndHour – trading hours.
    • TakeProfit / StopLoss – protective levels in price.

This example demonstrates a minimalistic RSI crossover system built with the high-level StockSharp API. It can be used as a template for further experimentation.
