Hello, csvp how to explain the disappearance of my list of indicators, an indicator bought and installed which worked until today?
Login into your MQL5 account with your: hugnka1 username and not your email and try again in the Purchased section of your Market tab.
Als make sure that you've purchased this indicator with your MQL5 account: https://www.mql5.com/en/users/hugnka1/market
Connectez-vous à votre compte MQL5 avec votre nom d'utilisateur: hugnka1 et non votre email et réessayez dans la section Achats de votre onglet Marché.
Assurez-vous que vous avez acheté cet indicateur avec votre compte MQL5: https://www.mql5.com/en/users/hugnka1/market
indeed, this is what I did after the purchase and it worked but suddenly it disappeared this morning
It may be for several reasons, for example:
Contact the Service Desk then.
So, this indicator was not vanished from your purchases, but from your installed indicators.
You need to install it again, as Sergey suggested.
Yes, you lose an activation after major windows upgrades, but MQL5.com usually credits 1 extra activation in such updates.
It happens automatically and universally for all MQL5 members after each major windows update, not on a personal level.
