Difference in gains between getquin and trading view?

$MSTR (-6,56 %) I am using trading view for quick overviews and planning while getquin for portfolio tracking. Crrently getquin shows -0.15% gains while trading view +1.15%. Why? In my investment that makes quiet a big difference. I have premium / payed memberships in both apps. So why the difference? Which is right?
