For the ‘Order Data’ Stream I am wondering where to get the ‘order quantity’ from the response. So from the API documentation: https://binance-docs.github.io/apidocs/futures/en/#event-order-update my understanding is that it’s either ‘q’ or ‘z’ in the payload.
Unless the API documentation for that part is outdated, it doesn’t look like its the ‘original quantity’, since that would be the quantity of the initial order. Can someone confirm its ‘z’ in the response payload?
Example: open 1 order of 1.0 BTC, only 0.1BTC is filled, remaining is 0.9BTC. Where should the information, being filled for 0.1BTC, be found stating that this order has been PARTIALLY_FILLED with 0.1BTC.
