Hi all, I'm increasingly running into issues using backtrader where data appears to be missing in the matrix. The attached screenshot shows one example of this (fairly recent) but my experience is that this is a much bigger issue as you go further back in time. Can this be fixed, and if so, how? I imagine that in some instances (especially as you go further back) the missing data may be for an option that simply wasn't listed at that time. However, I think that more often than not, there is just some hiccup in pulling the data from the server/database into the Matrix. It is these instances that I'm hoping there is a quick solution. I've found that shutting down and restarting usually doesn't resolve the issue. Neither does refreshing the matrix. Thanks for the help and input.
