QL Engine Weather — When Is the Engine Right?

QuantLogix's QL Foresight engine publishes daily probabilistic forecasts and resolves every one into a public Brier-score record. Engine Weather splits that record by the market regime on each forecast day — trend (up, down, or flat) and volatility (calm or stormy) — so you can see the conditions where the engine is genuinely well-calibrated versus where it struggles. The regime is read only from data available on the forecast day, and every resolved call is included. A coin flip scores 0.250; lower Brier is better.

When is the engine right?

QL Foresight keeps one blended calibration number. This splits it by the market weather on each forecast day — trend and volatility — so you know the conditions where the engine is genuinely sharp, and where it isn't. Brier score is lower-is-better; a coin flip is 0.250.
