Equity-Linked Position Sizing with Leverage and a Maximum Cap

Summary

This position-sizing example links trade quantity to account equity. It divides equity by a leverage parameter to derive a benchmark, rounds that benchmark down to a whole number with a minimum of one, then adjusts the quantity in unit steps toward that benchmark. A maximum-position setting and a platform risk limit cap the size. The example’s entries are generated separately by a moving average crossover: an upward cross opens long exposure and a downward cross opens short exposure. The stated parameters and published test settings use BTC/USDT futures, but no backtest results are provided.

The intended effect is to let position size rise as equity grows and shrink as it falls, compounding exposure while imposing limits. However, larger positions also magnify losses, and frequent equity-driven adjustments or excessive leverage can increase risk. The document offers possible refinements such as minimum adjustment steps, conditional sizing, or temporarily fixed size. The sizing rule alone does not define a risk budget per trade or ensure drawdown control; outcomes depend on leverage interpretation, platform sizing behavior, fees, and the entry strategy.

Key ideas

• Trade quantity is tied to account equity through a leverage-based benchmark.
• The example adjusts size in unit increments and applies a maximum-position constraint.
• Moving average crossovers determine long and short entries independently of the sizing calculation.
• Equity-linked growth can compound exposure, while magnifying losses as positions increase.
• The document lists BTC/USDT futures test settings but reports no performance results.
