Modeling Spread Costs for One-Bar-Ahead Forecast Strategies

Summary

This indicator is designed to help assess how spread affects the potential profitability of strategies that forecast the market one bar ahead. Its output can be treated as a unit-volume position in a custom tester, allowing a researcher to consider accuracy requirements when setting strategy targets or optimizing a model.

A single precision parameter represents the assumed probability of a correct forecast. The indicator determines the next bar’s direction from the change between consecutive closing prices, so its classification may differ from the displayed bar color when a price gap occurs. It omits the final histogram bar because the following close is not yet available. The document explains the intended use and calculation caveats but supplies no evidence that a given forecasting strategy is profitable or that its accuracy estimate will persist in live trading.

Key ideas

• The indicator helps examine how spread may affect one-bar-ahead forecasting strategies.
• Its precision setting represents the assumed chance that a forecast is correct.
• It classifies direction using the change between successive closing prices, which can differ from visual bar color around gaps.
• The final bar is unavailable because its next closing price has not formed.
• The indicator is a modeling aid and does not establish live strategy profitability.
