Post From: custom DTC trading service — new order not correlating with local order record

This is definitely a problem with the Order IDs. They must be matching. That is with certainty. It is completely dependent on the order IDs. For order IDs only use these two fields:
ServerOrderID
ClientOrderID

Reference:
Trading Related Messages: ORDER_UPDATE [s_OrderUpdate structure] Server >> Client

Do not change them. They must be constant throughout the life of the order. Sierra Chart is going to set the client order identifier as the client.

We have not done testing but looking at the Sierra Chart parsing of JSON fields, whether there is quote marks or not, around the order identifier, does not matter. But it is important that it is plain ASCII text.
