SMA20/50 Short-Only Crossover Strategy

Summary

This document describes a short-only trend-following system built around the crossover of 20-period and 50-period simple moving averages. A downward cross opens a short position, while an upward cross closes it. The source implementation uses the crossover events to generate orders and chart markers, with the stated sizing set to 100% of available equity. The published backtest settings specify BTC/USDT futures, daily bars, and a January-to-March 2025 test window, but the document gives no performance results.

The discussion identifies familiar limits of moving-average systems: lagging entries and exits, whipsaw signals in sideways markets, and exposure to rallies because the rules only trade short. It also notes that full-capital sizing and the lack of a separate stop-loss can leave substantial drawdown risk. Suggested extensions include trend or volatility filters, higher-timeframe confirmation, volatility-based sizing, explicit stops and targets, trading-session filters, and realistic fees and slippage. These are recommendations rather than tested improvements; the document provides no evidence that the strategy is profitable or that its suggested 15-minute use was validated.

Key ideas

• A short entry is triggered when the 20-period SMA crosses below the 50-period SMA.
• The short position closes when the 20-period SMA crosses back above the 50-period SMA.
• The described implementation uses all available equity and has no separate stop-loss order.
• Sideways markets can produce repeated false crossovers, while rallies are outside the strategy’s short-only scope.
• Position sizing, transaction costs, filters, and exit rules are proposed areas for further evaluation.
