Short Support Breakouts with Volume and ATR-Based Stops

Summary

This short-only method looks for price to break below the lowest low over a recent lookback period, with a buffer applied to the support level. It requires trading volume to meet or exceed its moving average and suppresses signals when the recent price range is small relative to ATR. The described configuration uses a 20-period support lookback and volume average, a 14-period ATR, and a sideways threshold of 1.5 ATR. The script specifies an initial ATR-based stop and a trailing stop intended to adapt to changing volatility.

The document explains the rationale for combining support breaks, volume confirmation, and range filtering, and identifies reversal, gap, and single-timeframe risks. It suggests higher-timeframe trend checks and trade limits as possible safeguards. A sample SOL-USDT futures backtest window is given, but no returns, drawdowns, or trade statistics are reported. The written description refers to a breakout buffer condition, while the code expresses the comparison as price at or below support multiplied by the buffer; that implementation detail should be reviewed when reproducing the rules.

Key ideas

• A short signal requires a close below a recent support level adjusted by a breakout buffer.
• Volume must meet or exceed its moving average for the signal to qualify.
• Signals are filtered out when the recent range is small relative to ATR.
• Initial and trailing stops use ATR to scale risk controls with volatility.
• The sample SOL-USDT futures configuration has no reported performance metrics.
