Dual SMA Crossover Signals and Their Whipsaw Risks

Summary

This document explains a trend-following strategy that compares short- and long-period simple moving averages. A bullish signal occurs when the shorter average crosses above the longer one; a bearish signal occurs when it crosses below. The supplied configuration uses 9- and 21-period averages on BTC/USDT futures, with a one-hour chart and a 15-minute base period. The accompanying script enters long or short positions on those crossovers and plots the signals.

The document describes the approach as easy to understand and parameterize, while warning that crossovers can whipsaw in sideways or volatile markets. It also notes that results depend on the chosen periods and suggests filters, additional indicators, and stop or profit-taking rules as possible refinements. Although backtest settings are provided, no performance statistics or comparative evidence are reported, so the stated advantages are not demonstrated by results in the text.

Key ideas

• A short SMA crossing above a longer SMA triggers a bullish entry signal.
• A downward crossover triggers a bearish entry signal.
• The example uses 9- and 21-period averages on BTC/USDT futures.
• Sideways price action can produce false signals and repeated reversals.
• The document provides backtest settings but reports no performance metrics.
