WebMy idea was: if regressor predicts a positive return and classifier confirms it with a buy class and a relevant predict_proba (maybe a threshold is needed, let's say >70%) go long setting take profit = predicted return. Otherwise go short with the same and opposite rules. In statistics, an augmented Dickey–Fuller test (ADF) tests the null hypothesis that a unit root is present in a time series sample. The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity.
