@xmatthias thank you very much for your detailed answer, I want to make this exchange work and I'll try writing missing parts, since so far I was able to use...

Thank you very much! I have found an interesting bug in CCXT that prevented proper candle downloading. Fixed that, keep experimenting. Looks feasible, but might take some time.
