@bluepintail sorry, I pushed a few commits that weren't ready for prime time. Will have a working version up later today

Please let me know if you're still having issues

Thanks. I just did a fresh install but now when I try and run I get:

NOTICE: util: Error reading JSON from cache/earliest_timestamps.json

I've checked in the binance_downloader/cache folder and there's no earliest_timestamps.json file.

I will change the wording to be less confusing, but the downloader should have still run normally. That's just letting you know there wasn't already cached data, and it pulled earliest timestamp for that currency pair from the server instead of using a cached value.

If it failed to download, can you send the rest of the output after the above NOTICE line?

Thanks

Ah OK, here's the full trace:

I was able to get it to work when I copied the earliest_timestamps.json file from the previous installation and I also had to manually create the downloaded folder.

Thanks. I think I have an idea of what the issue might be. Will take a look at the code tonight and have a fix soon.

Fixed and tested with a missing earliest_timestamps.json

Thanks, and let me know if you spot any other issues.
