Thanks for the answer, Sphin.

I read the thread you mentioned and checked the brokers.

But it's not that what I wanted. The brokers have only a very limited set of crypto currencies (Bitcoin, Ethereum and sometimes Litecoin).

I hoped to let Zorro work on the real crypto currencies exchanges like Poloniex which have many different crypto currencies because the smaller coins are very volatile and have enormous growing and shrinking of their value.

But until now I couldn't find any hint how to use them with Zorro.

The only hint I read yesterday was the use of "API keys", what is not supported by Zorro AFAIK. Does anybody have more knewledge about these API keys and how to use them?

Kind regards, Peter
