Hi Mcteilchen, I want to clarify one thing. There is an API and then there is an account associated with the API. I use zorro on the same API (OANDA) but I had to use two different accounts to prevent conflicting trades. Each zorro instance is running on it's own account. That was the only way I was able to run two different z systems. My zorro set up is account one zsystem 1 and account 2 zsystem2.
