TypeError when fetching ticker in Python 3.6

See original GitHub issue

Version 1.4.79, getting a type error when trying to fetch ticker info. Just posting this here in case other people have ran into it, will try and figure out a fix tomorrow when I have some time… First half of the stack trace is my stuff, but it shows the calling method and the exchange/symbol so that might help.

I was on a super old version (ccxt==0.1.63) which for some reason was accepting USDT-BTC but this symbol/id stuff you explained is way better anyway - I was doing the mapping between exchanges myself so I’m glad to upgrade and have you guys do it. Thanks for taking a look!

why not BTC/XXX or YYY/BTC? It should be a pair of currencies with a slash (a symbol) ))

I know but that’s how to reproduce the traceback 😉
