Universal XBody Strategy: Daily Signals from Changes in Candle Bodies

Summary

The XBody strategy is a daily, rule-based system presented for stocks, indices, and forex, with parameters optimized by its author on the CAC index. It calculates candle body size as close minus open, then takes the change in that value over time and sums it across a configurable period. Two thresholds separate positive and negative readings. Four selectable modes compare the readings with their prior values to generate directional signals, while an inversion parameter can reverse those signals. The rules enter long or short positions at market and disallow cumulative orders.

The suggested workflow is to optimize the period, mode, and signal direction first, then tune the two filters; an average-true-range-based stop is mentioned as an optional addition but is not included in the shown rules. The document provides a specific CAC configuration and says it was optimized over a historical span, but reports no performance statistics or out-of-sample validation. Optimization on one instrument may not transfer to other markets, and repeated parameter selection can overfit historical data.

Key ideas

• The strategy sums changes in candle body size over a configurable lookback period.
• Thresholds and four comparison modes determine long or short signals.
• A signal inversion parameter can reverse the direction of the trades.
• The author recommends optimizing core parameters before tuning filters.
• The CAC-focused optimization is not accompanied by performance metrics or out-of-sample validation.
