The code above works fine on Go Markets, as that's who I am using. (must be used on demo accounts only, as it is not really profitable)

1) Make sure you're using latest version of Zorro (at least version 1.50)

2) If not Go Markets, then make sure the broker allows EA trading for binary options (BO).

3) If Go Markets, then broker needs to enable binary options trading on your account. You will need to contact their support for this.

4) Check your time frame, most brokers (maybe all of them?) don't allow BO EA trading on time frames below 5 minutes.
