NSE Index Strategy with Entry Exit Markers

This strategy goes long when price is above a trend SMA and the RSI crosses above an oversold level. An ATR-based stop loss and take profit manage the position.

Details

  • Entry Criteria:
    • Long: price is above the SMA and RSI crosses upward above the oversold level.
  • Long/Short: Long only.
  • Exit Criteria:
    • close the long position when price hits ATR-based stop or take profit.
  • Stops: ATR-based stop loss and take profit.
  • Default Values:
    • SmaPeriod = 200.
    • RsiPeriod = 14.
    • RsiOversold = 40.
    • AtrPeriod = 14.
    • AtrMultiplier = 1.5.
    • CandleType = TimeSpan.FromMinutes(5).TimeFrame().
  • Filters:
    • Category: Trend
    • Direction: Long
    • Indicators: SMA, RSI, ATR
    • Stops: ATR-based
    • Complexity: Basic
    • Timeframe: Daily
    • Seasonality: No
    • Neural networks: No
    • Divergence: No
    • Risk level: Medium
