ATR-Scaled Momentum Breakouts from Daily Price Changes

Summary

This strategy treats a large one-day price change as a possible continuation signal. It computes the absolute change in closing price and compares the signed move with the prior bar’s average true range multiplied by a configurable factor. A rise beyond that threshold triggers a long entry; a sufficiently large fall triggers a short entry. The stated defaults use a 14-period ATR and a multiplier of 2, with position size set as a percentage of equity. Because the threshold scales with recent volatility, it rises when measured volatility is higher and falls when volatility is lower.

The document presents this as a momentum breakout concept and discusses delayed reactions, frequent trading, parameter overfitting, and uneven performance between long and short sides. Published settings specify BTC/USDT futures and daily strategy bars with hourly base data, but no performance figures are provided. Although the explanatory text refers to ATR-based stop management, the included source uses ATR as an entry threshold and contains no explicit stop-loss exit. The actual execution and risk behavior therefore differ from that description. Transaction costs, the choice of direction, and out-of-sample testing would matter in evaluating the approach.

Key ideas

• Entries are triggered when the signed closing-price change exceeds a multiple of ATR from the prior bar.
• The volatility-scaled threshold changes with recent market movement.
• The documented defaults are a 14-period average length and a multiplier of 2.
• The source does not implement the ATR stop loss described in the explanation.
• The document supplies no performance results and identifies overfitting and trading costs as concerns.
