New Order Single (35=D)

The New Order Single message facilitates the submission of an order to the Central Limit Order Book (CLOB). Upon receiving this message, the FIX Gateway processes the request and provides a response in the form of an Execution Report or Business Message Reject, depending on the outcome of the order submission process.

This message serves as the primary method for initiating new trading orders within the system, enabling users to specify key order parameters such as instrument symbol, quantity, side (buy/sell), and price.
