It's normal to use the FMZ public test server. If you use your own server, you get an error, GetOrder ((4216312375): invalid order id I don't know where the problem is, I didn't last year, I re-installed the server this year, I suggested this this year, the policy code hasn't moved.
Inventors quantify - small dreamsHello, as the API interface has added new features, the order ID format has been modified, which should be fine if you are using an ID obtained from another FMZ interface. For example, the ID returned by the exchange.Buy function is passed to the GetOrder function, which complies with the format requirements and does not return an error. Did you directly use the ID recorded in the Info field as the parameter for GetOrder?
