I have set up a test computer that only run QR 2007 Beta and TS9.1. I am running it side by side with another computer with QR 2021.08 b1601 and TS9.1. On both computers I set up tick charts and 1min charts. Now being weekend and only crypto are live, I test on BTC and ETH.
I do not use tick charts and 1min charts but am doing this just for the purpose that I have a visual that the feed/charts are alive and updating. So far they been running for about 24 hours and there is no stoppage. I do realize now and then the QR 2007 beta may skip some ticks, about 10 ticks or thereabout in 15 minutes. While sometimes there is no skip. Minimal effect on the 1min charts and defintely no effect on 5min and higher charts.
