liwenlueHi, how do you get the order update, you haven't received the order information.

fyrDo you need to write it yourself? /upload/asset/21b18cce8439c5312c140.png

Difficult to quantifyThe method in this example seems to be only applicable to a currency-based contract, right? I tried to change the contract address to a u-based contract, and found that I couldn't actively query "balance", "account", "position" and so on via websocket.

Inventors quantify - small dreamsJust tested, this example can change the local address of the Rion to the local address of U, the order information is not required to subscribe, it will be pushed directly. Once tested, the cancellation of the re-order will be pushed an order change message.

liwenlueThe problem is at this point, the binary has a subscription method similar to @balance that includes transaction data, but the u subscription data is not subscribed, so I asked the binary service to let me directly use the wss://fstream.binance.com/ws/XaEAKTsQSRLZAGH9tuIu37plSRsdjmlAVBoNYPUITlTAko1WI22PgmBMpI1rS8Yh (listenKey) to get all the data re-processed, but I used this method that seems not to be available to the inventors, I don't know how to operate it, if there is a problem, try it, thank you, or I can give you an example code for subscribing to the u subscription.

Inventors quantify - small dreamsHello, you need to subscribe to the corresponding channel to have push data, specifically you can see how to subscribe on the documentation of the exchange, in the example only these subscriptions: ``var arr = ["balance", "account", "position"] ```

Inventors quantify - small dreamsIt's safe to say that it's at the bottom of the heartbeat, and you don't need a strategic level ```xxx.write (゚) ` (゚) to write messages.

Inventors quantify - small dreamsAccording to the documentation of the exchange.
