Hi Ben10power,
The servers generating the strategies run 24 hours a day, and any strategies that pass the criteria are added to a collection. On Saturdays, all of the EAs in the huge collections are tested against the historical data from the brokers, and the best are uploaded or kept in the app. But once they’re in the app, they’re tested every 30 minutes against the historical data and arranged in the app according to the metric you have selected.
Cheers,
Ilan
