Multi-EMA Crossover Trading with a Long-Term Trend Filter

Summary

This trend-following strategy uses an 8-period EMA crossing a 21-period EMA to trigger entries and exits. A long entry also requires the 8-, 21-, and 50-period averages to be above the 200-period EMA, while signals are confirmed at candle close. The described rule set is long-only: a downward cross of the short averages closes the position, without requiring the long-term filter.

The document explains the intended benefit of filtering short-term crosses through a longer-term trend measure, and notes that lag and sideways markets can produce drawdowns or repeated false signals. It has no reported performance results. Published settings identify a BTC/USDT futures backtest period and timeframe, but provide no statistics with which to assess outcomes. Stop-loss rules and position sizing are absent; the document suggests these, along with parameter checks and additional filters, as possible improvements.

Key ideas

• An upward 8/21 EMA cross triggers a long entry only when the 8-, 21-, and 50-period EMAs are above the 200-period EMA.
• Signals are confirmed after the candle closes.
• A downward 8/21 cross closes the long position, with no explicit stop-loss or position-sizing rule.
• Moving-average lag and choppy markets can lead to late entries, false signals, and overtrading.
• The published backtest settings do not include performance results, so they do not establish profitability.
