Buying After a Large Single-Period Price Drop

Summary

This strategy seeks short-term rebounds by buying after a sharp decline. It measures the percentage change from the previous candle’s close and triggers a long entry when the decline exceeds 5%, sizing the purchase using the account balance and current close. It records the entry price and exits when the price rises above the position’s average entry price. The example backtest configuration uses BTC/USDT futures with daily bars over a period from June 2023 to June 2024.

No backtest performance statistics are provided. The source code also makes repeated entries possible whenever the decline condition recurs, and it has no explicit stop loss, so continued declines may deepen losses. The document flags trading costs, low volatility, and drawdowns as concerns, and suggests stop-loss rules, signal filters, and more dynamic sizing as possible extensions. Those proposals are not tested in the material.

Key ideas

• A decline exceeding 5% from the prior close triggers a buy signal.
• The strategy exits when the current close exceeds the position’s average entry price.
• The example is configured for BTC/USDT futures on daily bars from June 2023 to June 2024.
• The source does not specify a stop loss and may enter again when the decline condition recurs.
• The document identifies transaction costs, further price falls, and weak volatility as risks.
