Logon (A) message is used by a TT FIX Gateway to begin a new or continue an existing session with a\n\t\t\tthird-party FIX acceptor.<\/p>\n\t\t<p>The following data flow illustrates a typical logon sequence between a TT FIX Gateway and a third-party FIX\n\t\t\tacceptor:<\/p>\n\t\t<ol>\n\t\t\t<li>The TT FIX Gateway opens a socket connection to the third-party FIX acceptor.<\/li>\n\t\t\t<li>The TT FIX Gateway sends a Logon (A) message to the third-party FIX acceptor.<\/li>\n\t\t\t<li>If the third-party FIX acceptor detects any errors, it will respond with a Logout (5) message with the\n\t\t\t\treason for rejection in Tag 58 (Text), and closes the socket connection.<\/li>\n\t\t\t<li>The third-party FIX acceptor examines the value of Tag 141 (ResetSeqNumFlag).\n\t\t\t\t<ul>\n\t\t\t\t\t<li>If Tag 141 (ResetSeqNumFlag) is set to N, the third-party FIX acceptor compares the value of Tag\n\t\t\t\t\t\t34 (MsgSeqNum) in the Logon (A) message against its current sequence number.\n\t\t\t\t\t\t<ul>\n\t\t\t\t\t\t\t<li>If MsgSeqNum is less than the expected sequence number, the third-party FIX acceptor\n\t\t\t\t\t\t\t\tstops processing the logon attempt, sends a Logout (5) message as its response, and\n\t\t\t\t\t\t\t\tcloses the socket connection.<\/li>\n\t\t\t\t\t\t\t<li>If MsgSeqNum is greater than sequence number the third-party FIX acceptor expected, the\n\t\t\t\t\t\t\t\tlogon process continues normally. However, after the logon process completes, the\n\t\t\t\t\t\t\t\tthird-party FIX acceptor sends a Resend Request (2) message.<\/li>\n\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t<\/li>\n\t\t\t\t\t<li>If Tag 141 (ResetSeqNumFlag) is set to Y, the third-party FIX acceptor expects the value of Tag\n\t\t\t\t\t\t34 (MsgSeqNum) in the Logon (A) message to be 1.\n\t\t\t\t\t\t<ul>\n\t\t\t\t\t\t\t<li>If Tag 34 is not 1, the third-party FIX acceptor stops processing the logon attempt,\n\t\t\t\t\t\t\t\tsends a Logout (5) message, and closes the connection.<\/li>\n\t\t\t\t\t\t\t<li>Otherwise, the logon process continues normally.<\/li>\n\t\t\t\t\t\t<\/ul>\n\t\t\t\t\t<\/li>\n\t\t\t\t<\/ul>\n\t\t\t<\/li>\n\t\t\t<li>The third-party FIX acceptor sends a Logon (A) message to the TT FIX Gateway.<\/li>\n\t\t<\/ol>\n\t\t<div>\n\t\t\t<h4>TT FIX Price Gateway<\/h4>\n\t\t\t<p>The TT FIX Price Gateway will only support non-persistent FIX sessions. In other words, it will always\n\t\t\t\tsend a Logon (A) message with Tag 34 (MsgSeqNum)=1 and Tag 141 (ResetSeqNumFlag)=Y when initiating a\n\t\t\t\tconnection. As a result, the FIX session will terminate when the connection does.<\/p>\n\t\t<\/div>\n\t\t<div>\n\t\t\t<h4>TT FIX Order Gateway<\/h4>\n\t\t\t<p>When the TT FIX Order Gateway is started for the first time, it will send a Logon (A) message with Tag 34\n\t\t\t\t(MsgSeqNum)=1. When there are unscheduled restarts, the standard FIX message sequence number negotiation\n\t\t\t\twill take place. After scheduled message sequence number resets, the TT FIX Order Gateway will send a\n\t\t\t\tLogon (A) message with Tag 34 (MsgSeqNum)=1.<\/p>\n\t\t<\/div>\n\n\n\n<div class=\"related-information-wrapper wp-block-twentytwentyfive-child-tt-related-information\">\n    <h2 class=\"related-information-title\">Related Information<\/h2>\n    <ul>\n                    <li>\n                <a href=\"https:\/\/library-staging.tradingtechnologies.com\/tt-fix\/tt-fix-gateway\/session-messages-tt-fix-gateway\/logout-5\/\">Logout (5)<\/a>\n            <\/li>\n                    <li>\n                <a href=\"https:\/\/library-staging.tradingtechnologies.com\/tt-fix\/tt-fix-gateway\/session-messages-tt-fix-gateway\/resend-request-2\/\">Resend Request (2)<\/a>\n            <\/li>\n                    <li>\n                <a href=\"https:\/\/library-staging.tradingtechnologies.com\/tt-fix\/tt-fix-gateway\/session-messages-tt-fix-gateway\/sequence-reset-4\/\">Sequence Reset (4)<\/a>\n            <\/li>\n            <\/ul>\n<\/div>\n\n","protected":false},"excerpt":{"rendered":"<p>Purpose Used to establish a connection between a TT FIX Gateway and a third-party FIX acceptor Message Directi [&hellip;]<\/p>\n","protected":false},"author":2,"template":"","meta":{"_acf_changed":false,"footnotes":""},"docs-category":[466],"class_list":["post-7108","doc","type-doc","status-publish","hentry","docs-category-session-messages-tt-fix-gateway"],"acf":[],"_links":{"self":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/doc\/7108","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/doc"}],"about":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/types\/doc"}],"author":[{"embeddable":true,"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"version-history":[{"count":0,"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/doc\/7108\/revisions"}],"wp:attachment":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/media?parent=7108"}],"wp:term":[{"taxonomy":"docs-category","embeddable":true,"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/docs-category?post=7108"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
