Lessons learned about CCXT Python package for 3 largest crypto exchanges Bitmex Binance OKex
Please be advised
Using CCXT with a recent script I sourced to download generically from various exchanges is powerful. I have thought come across some severe limitations in the process.
- Binance appears to be the most reliable since you have the widest selection of timeframes you can use. Also, you can download up to 1000 rows into a comma separated value file as well.
- Both Bitmex and OKEx offer some form downloading limit of 500 which really messes up my analytical Python script. When downloading, you can only seem to have a limit of 400 to just under 500. This seems to work only work for lower time frames like 1 or 5 minutes. As the timeframe selection is very limited compared to Binance.
I am unsure of other crypto currency exchanges what limitations offer but I will stick with Binance for now as the only exchange of interest. It seems that the others offer much lower daily volume which means slower fills due to lower liquidity. Â Also the other exchanges have weird download exceptions which also means the charting will not work as well.
Further note about Bitfinix
I just execute 5 request no different than Binance, Bitfinex starts thinking it is being attacked where it responds:
ccxt.base.errors.DDoSProtection: bitfinex {“error”:”ERR_RATE_LIMIT”}
Pretty pathetic architecture if you ask me.
In summary, it just seems that Binance works out of box for both downloading and charting.
Update: Which Bitcoin crypto currency bot project? Gekko vs ccxt vs Tribeca vs Blackbird
