Migration to postgreSQL or mongoDB

[exmoond]

Tried import mode instead market watcher to test ?

yes , import works fine , simulation works fine , when you want to run paper trader , it seems that it do not fetch data from market watcher , problem exist only with mongodb.
Postgreqsl and sqlite are working good.

Like you see on attached screenshot strat runner is not fetching data from market watcher ,  tested graphical and text on : windows10 with bash, ubuntu , centos, windows 10 from cmd ,  ubuntu cloud server , in all situations there is problem only when mongodb i set as database.

market watchers were started with 1 min difference in time , database been purged before every test, and data been re-imported
