Post From: Replay divergence for multiple charts

Hello, I wanted to replay multiple charts in sync, but when doing it using Chartbook or Link Number replay I can only replay them with 1 second set and that is too slow. My solution to that is a custom study I wrote with ACSIL which uses sc.StartChartReplay() to trigger all charts separately with a for loop and this gives me exactly what I want - I can have multiple charts replaying with 120x speed and everything is working as expected. I was concerned that charts might diverge so I wrote another ACSIL study to track the divergence between 2 charts using sc.LatestDateTimeForLastBar from the current chart the study is applied on and a persistent SCDateTime& read from another chart which has the corresponding value for sc.LatestDateTimeForLastBar. This seems to do the trick more or less, but I am constantly seeing divergence of about 300ms even though when I look at the charts this doesn't seem to be true. I think my approach is a bit overengineered at this point so I wanted to reach out to you and ask if you can share a better way to track if 2 charts' replays are in sync ? Or even better - a better of doing fast replays of multiple charts. All the best, Date Time Of Last Edit: 2024-11-22 15:44:54
