Hello Nicolas,

Why does this screener does bring back any result ?

ecartbol = Bollingerup[60](close)-Bollingerdown[60](close)
SCREENER[ecartbol < average[200](ecartbol)]

Thank you for your feedback

Because SCREENERS with IG have a 254-bar data history limit (1024 with PRT direct).

You are using a 200 + 60 = 260 periods. Try using 50 periods for BB.

You can still use 200 periods with SMA. Should you want to use an EMA, then you could barely use 80 periods for the average, since EMAs require many more bars to be calculated.
