The Logon message (tag 35=A) is used by market participants to establish a Financial Information eXchange (FIX) session with the National Digital Asset Exchange (NDAX). The Logon message must be the first message sent by the client when requesting to initiate a FIX session. It must be received by NDAX within 5 seconds of establishing the connection, or the connection will be closed. The Logon message is used to initiate communication between the client and NDAX and to establish the parameters of the FIX session, such as the version of the FIX protocol being used and the maximum message size. By sending a Logon message, the client can request to establish a FIX session with NDAX and begin trading digital assets on the platform.
