Everything working fine, then suddenly this evening it starts chugging and not responding whenever I try to replay or run an automated backtest. I've closed the chart book and opened a new chart, set the days count to 1 and the spreadsheet rows to 150 (used to have it on 10 days and 1000 rows). I haven't added any new studies or custom studies. What could be the problem?

I now see that my .scss file is over 50MBs. All my other .scss files were under 2MBs. I checked and there are still only 200 rows of data being stored. Any suggestions as to how I can reduce the file size or what might have gone wrong?

Check for sheets that are not being used and delete them.

I had four sheets used as backups (since there's no versioning tool). But very little data in them.

The first thing is to check the replay mode:

Try using this replay mode: Calculate Same as Real Time


You just need to delete the data from the unused rows and columns:
Using the Spreadsheet Study: Clearing Old Study and Other Data from Spreadsheets

Also use a lower Replay Speed.
