Three-EMA Trend Entries with an EMA Crossover Exit

Summary

This long-only strategy uses 8-, 18-, and 50-period exponential moving averages to combine a short-term entry trigger with a broader trend filter. It buys when the closing price crosses above the 8-period EMA while price is above the 50-period EMA. It closes the position when the 8-period EMA crosses below the 18-period EMA.

The document explains that faster averages react sooner but can lag turning points and produce repeated signals in volatile markets. It suggests stop losses, additional filters such as volume or RSI, parameter testing, and checks across different instruments. Published settings show a BTC/USDT futures backtest over roughly one year, but no performance statistics or supporting results are reported. The written description sometimes refers to the 8-period EMA itself crossing the 18-period EMA for exit, while the implementation does use that condition; its entry description is less precise than the implementation, which specifically tests a price crossover above the fast EMA. These distinctions matter when reproducing or evaluating the rules.

Key ideas

• A price crossover above the 8-period EMA initiates a long only when price is also above the 50-period EMA.
• The position closes when the 8-period EMA crosses below the 18-period EMA.
• The 18-period average provides an intermediate trend reference, while the 50-period average filters entries by broader direction.
• Moving-average signals can lag reversals and whipsaw in volatile conditions, increasing trading costs.
• The published BTC/USDT backtest settings include no reported performance evidence, so robustness remains unestablished.
