Please use the BITMEX process. The log shows the 429 problem ratelimit exceed. But if I want to read this error in the program, after using the exchange.IO package, the error is only false, there is no code for these error details.
ShepherdingGetLastError can be used to read this error message when reading to the IO function returning a value of false. Specific uses can be found in the fmz api documentation.
The Earthvar openId = exchange.IO (("api", "POST", "/api/v1/order", "symbol=XBTUSD" + "&side=Sell" + "&execInst=ParticipateDoNotInitiate&price=" + price+ "&orderQty=" + quantity); You can get it through Log ((openId)).
