On some symbols it goes to download all the history that's available. As you can see on the example, it should have downloaded only a recent week, but went as far back as 2023. The strategy is empty.

If you have a data cached, a history request will add to that cache from where it ended. If it didn't do that, there would be gaps in the cache that would be a headache to deal with.
Makes sense. Removing the 5m quotes from IB folder solved the problem.
Why do you consider adding to the cache a "problem"?
The chart request would still return only the 1 week of data that you requested.

It was only in this particular case that I didn't want to wait. Usually I backtest on other fast quotes, and use IB only for trading, so longer period of quotes was excessive.
In general, I often noticed this behavior, it was not clear to me why on some symbols it goes so far to download.

I know it can be painful waiting for the IB downloads, but the download is required only once. Then you don't have to wait ever again for that data.
