Turtle-Style ATR Position Sizing and Breakout Exits

Summary

This Turtle-inspired system enters when price breaks above a recent high or below a recent low, then exits at a channel level on the opposite side of the position. ATR measures volatility and is used with account equity to calculate trade quantity, while the document describes ATR as a guide for risk and sizing. The listed defaults include an ATR period of 20, an ATR factor of 2, and entry and exit breakout settings of 20 and 10.

The source complicates the accompanying overview: both entry and exit levels use the exit-period input, and the entry-period setting is not applied. It also sets the long-only and short-only flags in a way that appears to disable those respective sides when selected. Although BTC/USDT futures backtest settings are provided, no performance results are reported. The document notes reversal, whipsaw, transaction-cost, and parameter risks; no evidence is presented that the proposed filters or optimizations improve results.

Key ideas

• The strategy enters on recent price-channel breakouts and exits at opposite channel boundaries.
• ATR and account equity determine the quantity assigned to a trade.
• The source uses the exit-period parameter for both entry and exit levels, leaving the entry-period input unused.
• The backtest configuration is reported without performance results, and choppy conditions may cause repeated trades.
