Overview
50 EMA + 200 EMA Short Strategy (Not Good) enters short when the fast EMA is below the slow EMA, the close crosses below the fast EMA within a defined lookback period, and a bearish candle forms below the fast EMA. Exits are handled through configurable percentage-based or ATR-based stop-loss and take-profit orders. Main settings include EMA lengths, ATR multiplier, lookback window, and profit or loss thresholds. Plots both EMAs and active exit levels directly on the price chart.
- Dual exponential moving average filter
- Crossunder trigger with configurable lookback
- Percentage or ATR-based profit target and stop loss
- On-chart target and stop level plots
