Short-Term EMA Crossover Signals with a Long-Term Trend Filter

Summary

This short-term strategy uses 9-period and 15-period exponential moving averages (EMAs) to generate crossover signals, with a 50-period EMA as a directional filter. A bullish crossover prompts a long entry only when price is above the longer EMA; a bearish crossover prompts a short entry only when price is below it. The stated trading horizon is one to five minutes, and the accompanying source also specifies BTC/USDT futures backtest settings over a short date range.

The document describes the signal logic and possible refinements, but provides no backtest performance results. It warns that fast averages can produce false signals, the longer average may not eliminate choppy conditions, and historical parameter choices may not generalize. It also notes that fixed stop placement can be poorly matched to changing conditions. Suggested additions include stochastic filtering, volatility-adjusted stops, parameter search, and machine learning; these are proposals, not demonstrated improvements.

Key ideas

• A 9-period EMA crossing above or below a 15-period EMA supplies the entry direction.
• The 50-period EMA filters entries according to whether price is above or below it.
• The described strategy targets short-term trading on one- to five-minute intervals.
• Fast EMA crossovers can generate false signals, and a longer trend filter cannot remove all whipsaws.
• The document suggests adaptive stops and added indicators but provides no performance evidence for them.
