Hello Ghome I apreciate your help. It's not Big Trade. It's EdgeProLine. I never added this study. It's a new trial so. it's seems it was added by default along Cloud levels and OHLC. I maybe wrong though. Maybe a former trial kept some data on my PC. I may not remeber having use them. Sometimes you start a trial and then work, family, etc prevent you from trying the platform fully. This time I should be able to use it everyday. Anyway, after restarting Motivewave, I removed EdgeProLine and the bubbles were gone. But, adding the study back, to figure what I was missing, I found the settings which remove the bubbles. without removing the line. You must choose "none" from Displayed info and voilà.
