Thx for your feedback on ccxt! Nice project you have here! )
Take a look at this table, it might be of interest to you:
Basically, we support all public and private methods out of the box already. All of them work with no exception. But not all of private methods have been completely wrapped into a common unified subset yet. We're trying to build an all-in-one unified API on top of their custom public and private APIs. And most of this work has been done already, but not all of it. All underlying public and private endpoints should work right away, though (they are all available in current version of ccxt).
So, you can fetch data, create orders, fetch balances, all you need for basic trading, all public and private API methods are there... Some methods of the unified API may still be missing, though, and we will be happy if you submit a PR ;) Here's our CONTRIBUTING doc. Also, feel free to open an issue if you encounter a difficulty or question regarding the library!
