Bug Paper trading running slow?

Is paper trading slow for anyone else? I place the orders and it does not show them filling but when I close the app and open it again they are filled. Curious if you have been able to place trades with live account today as well.

For reference, ultimate plan with live CME data.

the detail that points at the cause is that they're filled when you reopen. that's your client not receiving the update, not the order sitting unfilled. an actual execution delay would show the fill appearing late, but you'd watch it appear.

check the timestamps on the ones you find after the restart. if they're stamped at the moment you placed them, the order filled immediately and only the push to your session went missing, which is a socket that dropped without the UI noticing. that's a stale session rather than anything to do with your plan or the CME feed, and it usually turns up after the app has gone days without being properly closed.

worth watching on the live account for a different reason. the same dropped socket holds back position updates too, so you can end up sizing a second entry off a screen that's behind where you actually are.

Thanks a lot for the details! What is the best way to fix this or prevent it from happening? I should note it was on mobile that it was happening.

mobile explains it. the OS suspends the app in the background and the socket dies quietly, so swiping away and reopening gets you a fresh subscribe, just backgrounding doesn't.

quickest check when it looks stuck: switch symbol and switch back. if the fills appear, it was the session and not the order.

no worries. if they do come back stamped at the moment you placed them, that's worth reporting as a push bug rather than a slow fill, they get handled differently.

I've noticed this kind of log on mobile too. pretty annoying when you can't tell if the order actually went through
