2022-07-08 00:00:00 : 2022-07-08 00:00:00 Failed 5 timesThe algorithm is only able to download the same file 100 times. After that, self.Download() returns an empty string. Why is that, and is there a way to increase that limit? More importantly, will I encounter the same issue in paper/live trading? I am continuously changing the file so I need to be able to download it an unlimited amount of times. The problem is definitely on QC's end and not Dropbox as I have no issues downloading it endless times from a custom script.

Does anyone know if it applies to live or paper trading?

Hi HaakonÂ
We do not impose a rate limit on file downloads but often external providers do. Dropbox caps download speeds to 10 kb/s after 3-4 download requests. To ensure your algorithms run fast, only use a small number of small custom data files.
