Thank you very much for your e-mail. In general – bar replay should work fine and we are not really experiencing such problems (nor getting any similar reports from other users), that’s why I wanted to check if picking the bars directly from the chart (with their exact timestamps) works fine on your end.
You may also check if anything changes if you modify the timestamp display in Tools –> Preferences –> Intraday (e.g. to show START TIME OF INTERVAL or END TIME for example).
