Overview

This strategy combines multi-timeframe donchians to scalp short-term breakouts during a user-defined session. It belongs to short-term scalping strategies.

Strategy Logic

  1. Calculate day and short-term mid-points to form breakout zones across timeframes.

  2. Only trade during a customizable trading session. Enter on session start, exit on session end.

  3. Use real-time EMA of price as entry price. Breakout when price exceeds mid-point.

  4. Set stops outside breakout zones. Stop out when breakout fails.

  5. Close positions when price falls back near mid-point, confirming failed breakout.

Advantages

  1. Multi-timeframe combines to effectively filter false breakouts.

  2. Defined sessions avoid risks around major news events.

  3. EMA tracking allows timely entries in line with momentum.

  4. Stops help control risks.

  5. Forced session exit avoids overnight risks.

Risks

  1. Short-term breakouts may face whipsaws and stop outs.

  2. Some breakouts may not fully profit before session ends.

  3. Poor session definition could miss opportunities.

  4. No guarantee each breakout reaches expected profit.

  5. Optimization risks overfitting parameters.

Enhancement

  1. Test breakout parameters to find optimal combinations.

  2. Evaluate additional indicators to improve entry accuracy.

  3. Optimize trading session for profit vs risk balance.

  4. Research integrating take profit strategies to lock in gains.

  5. Test parameter differences across various symbols.

  6. Employ machine learning for dynamic parameter optimization.

Conclusion

This strategy attempts short-term scalping on limited session breakouts. With optimizations around false breakouts and risk controls, it can be refined into a pragmatic and efficient short-term system.
