Diagnosing Boolean Conditions in StockRanker Training

Summary

A user reports that a price-ratio buy condition never triggers during a year-long backtest, although the sell condition does. The response attributes the training error to StockRanker receiving only two factors, with a Boolean factor causing the model to fail. It suggests adding another factor or bypassing StockRanker and implementing the entry logic directly as rules.

The discussion is a brief troubleshooting note, not a validation of the price calculations. It provides no investigation of the close-price fields, threshold interpretation, or backtest data, so it does not establish why the buy condition produced no signals. Its practical lesson is limited to a reported StockRanker constraint and two possible workarounds; users should separately check their data and condition logic.

Key ideas

• The reported StockRanker training failure is associated with using only two factors when one is Boolean.
• Adding another factor is offered as one workaround.
• Implementing the entry condition directly as a rule is offered as another workaround.
• The note does not verify whether the price-ratio calculation or its inputs are correct.
