    Hi,

    it's been a while that I used the Performance (Forecasting Performance) operator, but if I remember correctly, the prediction trend accuracy just measures the proportion of examples where the prediction trend has been correctly predicted. In this case, the trend is either "up" or "down".

    Best,
