This strategy is a dual-direction trading system that combines Exponential Moving Averages (EMA) with time intervals. The system determines the main trading direction based on EMA relationships within user-defined fixed time intervals, while monitoring another set of EMA indicators for crossover signals or approaching the next trading cycle to execute reverse hedge trades, thereby capturing bi-directional trading opportunities.
The strategy operates on two core mechanisms: main trades at fixed intervals and flexible reverse trades. The main trades judge trend direction based on the relative position of 5⁄40-minute EMAs, executing trades at each interval (default 30 minutes). Reverse trades are triggered either by monitoring 5⁄10-minute EMA crossover signals or one minute before the next main trade, whichever occurs first. All trading occurs within a user-defined time window to ensure trading effectiveness.
This is a comprehensive strategy that combines trend following with reverse trading, achieving bi-directional opportunity capture through the coordination of time intervals and EMA indicators. The strategy offers strong customization capabilities and good potential for risk control, but requires parameter optimization and risk management refinement based on actual market conditions. For live trading implementation, it is recommended to conduct thorough backtesting and parameter optimization, along with specific adjustments based on market characteristics.
