message is used to reset the message sequence number when the FIX client and TT FIX message sequence numbers do not match. If the message omits Tag 123 (GapFillFlag), the value of Tag 36 (NewSeqNo) indicates the new starting sequence number.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If a FIX client or TT FIX needs to skip messages that would be included in a resend request, it sets Tag 123 (GapFillFlag) to <strong>Y<\/strong>, and the value of Tag 36 (NewSeqNo) represents the sequence number of the next message to be transmitted.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note<\/strong>: Non-gap fill resets should be used only to when the sequence number differences cannot be resolved.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For more information about sequence resets and gap fills, refer to the <a href=\"http:\/\/www.fixtradingcommunity.org\/FIXimate\/FIXimate3.0\/\">FIX specification<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related Information<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n\t\t<a href=\".\/Msg_Logon_A.html\">Logon (A)<\/a>\n\t\t<br>\n\t\t<a href=\"Msg_ResendRequest_2.html\">Resend Request (2)<\/a>\n\t\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Purpose Used to reset the message sequence number or gap fill Message Direction From TT FIX to FIX client and  [&hellip;]<\/p>\n","protected":false},"author":2,"template":"","meta":{"_acf_changed":false,"footnotes":""},"docs-category":[457],"class_list":["post-7097","doc","type-doc","status-publish","hentry","docs-category-session-messages"],"acf":[],"_links":{"self":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/doc\/7097","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\/7097\/revisions"}],"wp:attachment":[{"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/media?parent=7097"}],"wp:term":[{"taxonomy":"docs-category","embeddable":true,"href":"https:\/\/library-staging.tradingtechnologies.com\/ja\/wp-json\/wp\/v2\/docs-category?post=7097"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
