2Mars OKX Strategy

This strategy combines a moving-average crossover with a SuperTrend filter. Bollinger Bands provide profit targets while an ATR-based stop loss limits risk.

Rules

  • Long: Signal EMA crosses above basis EMA and price is above SuperTrend.
  • Short: Signal EMA crosses below basis EMA and price is below SuperTrend.
  • Exit: Take profit at Bollinger upper or lower band, or stop loss at ATR multiplied by a factor.

Indicators

  • EMA
  • SuperTrend
  • Bollinger Bands
  • Average True Range
