Validating the order ID with https://contract.mexc.com/api/v1/private/order/get/ I can see the information for a valid order ID, but even just querying one order with /api/v1/private/order/batch_query always returns {"success":true,"code":0,"data":[]}
In the meantime I will need to query every order individually or get all the orders and create a map to find the positionId from the transactions returned from api/v1/private/order/list/order_deals though it would really be better if these just included the positionId along with the orderId
