Long-Short Trading with Fast and Slow SMA Crossovers

Summary

This strategy uses two simple moving averages of closing prices to switch between long and short positions. The described defaults are a 20-period fast average and a 50-period slow average. A cross of the fast average above the slow one opens a long position and closes the short; a cross below opens short and closes the long. The approach is intended to capture medium- to longer-term changes in direction while limiting activity to crossover events.

The document explains the basic trend-following rationale and notes that moving-average signals lag, so entries or exits can arrive after a move has begun. Price gaps and short-lived reversals can also produce losing signals. It suggests testing different periods, adding confirmation indicators, and using a stop loss. Published backtest settings identify BTC/USDT futures and a one-week sample, but no returns, trade statistics, or comparison are given. The stated periods and brief sample therefore do not establish that the strategy is profitable or robust across markets.

Key ideas

• A fast SMA crossing above a slow SMA triggers a long position, while a downward cross triggers a short.
• The described default periods are 20 and 50 bars.
• Opposite crossover signals close the prior directional position and initiate the other side.
• Moving-average crossovers can lag and may produce false signals during gaps or short reversals.
• The cited backtest setup provides no performance results, so it cannot establish robustness.
