Big Runner Strategy

The Big Runner strategy trades when the closing price and a fast SMA both cross in the direction of a slower SMA, indicating strong momentum. Position size is derived from a percentage of portfolio value multiplied by leverage. Optional stop-loss and take-profit levels manage risk.

Details

  • Entry Criteria:
    • Buy when close crosses above the fast SMA and the fast SMA crosses above the slow SMA.
    • Sell when close crosses below the fast SMA and the fast SMA crosses below the slow SMA.
  • Long/Short: Long and short.
  • Exit Criteria:
    • Optional stop loss and take profit based on entry price.
    • Opposite signal closes existing position.
  • Stops: Configurable stop loss and take profit percentages.
  • Default Values:
    • FastLength = 5
    • SlowLength = 20
    • TakeProfitLongPercent = 4
    • TakeProfitShortPercent = 7
    • StopLossLongPercent = 2
    • StopLossShortPercent = 2
    • PercentOfPortfolio = 10
    • Leverage = 1
