Volatility-Scaled Breakout Thresholds with Moving Average Confirmation

Summary

This breakout approach estimates volatility from the standard deviation of log returns, annualizes it for the chart timeframe, and scales it back to a one bar expected move. It places upper and lower thresholds around the prior close; a confirmed close beyond either threshold can trigger a trade, optionally filtered by a moving average. Exits can use fixed percentage stops and targets or a trailing stop tied to the expected move.

The document supplies example settings and code, but its claimed win rate and profit ratio are not accompanied by a stated test period, instrument, or validation procedure. Despite its name, the described calculation uses historical return volatility rather than implied volatility from option prices, and the annualization conventions may need scrutiny across chart resolutions. The text flags false breakouts, overfitting, costs, liquidity, and extreme market gaps, and suggests out of sample checks, position sizing, and additional filters.

Key ideas

• The strategy scales breakout thresholds using a volatility estimate derived from log returns.
• Thresholds are centered on the previous close and signals are checked after bar confirmation.
• A moving average can filter entries, while exits use fixed targets and stops or volatility linked trailing stops.
• The document reports performance claims without enough testing detail to assess their reliability.
• The volatility calculation is historical rather than an estimate of option implied volatility.
