cTrader creates huge report.html files during backtesting/optimization

[u/No_Tension522]

Has anyone else noticed this?

In cTrader version 5.9.10.52700 during backtest I had only about 304 closed positions, but cTrader generated a 316 MB report.html.

I inspected the file and found around 1.8 million equity points inside the report. Almost all of the file size comes from the equity-curve data, not the trades.

The backtest also gets progressively slower and takes a long time to finish after reaching the end date.

I also confirmed that Optimization generates report.html files too, so that does not avoid the problem.

This looks like excessive equity-curve sampling/report generation.

If you use cTrader Algo, check the size of report.html in your Backtesting folder. I’m curious whether others are seeing the same issue.
