Tradingview's stock screener is useless

[cassiopeia]

Has anyone used the Tradingview screener for premarket stocks, particularly smaller ones? I notice that it sometimes fails to list stocks which fit criteria until too late. I can sometimes temporarily fix it by left clicking the mouse every so often. It's as if the 10 second update doesn't work properly. Unfortunately sending a ticket to Tradingview calls up the screener again with the same settings, which effectively left clicks it, so it doesn't pick up the problem. I bookmarked the screener which was called up when a generated a ticket and ran it side by side with the same screener I'd bookmarked some days previously with identical settings. The old one had developed latency and failed to pick up stocks for up to 15 minutes on a 10 second renew.

It's really impractical to keep left clicking, in fact it really needs an audible alarm as well to be practical.

I even downloaded a program which records an automatic screenshot every 10 seconds so it can be compared to charts to prove the screener develops latency. Tradingview simply said they couldn't reproduce the problem.
