Seasonality (backtest)
A backtest's average return by calendar month and by weekday, with how often each was positive.
How to read it
A hit rate above 50% with a positive average is a consistent tendency; a high average from one huge month is not.
How to use it
Spot calendar effects in a strategy before trusting them.
Limitations
Each month has one observation per year of test — ten years is ten numbers, easily noise.
