Pretty okay for trading but there has been connection issues non stop for like a month now and it is incredibly frustrating. Website works fine and my internet is stable. It's literally just the app, don't know why. Edit 2/5/22: Connection issues appear to be much better. Still a little slower than I'd like but it is usable now. 2/15/22: Connection issues have returned. Not quite as bad as they were before but still makes the app literally unusable. Incredibly disappointing.
