The stock market doesn’t simply switch on at 9:15 AM and off at 3:30 PM. There are two additional sessions, one before the regular market opens and one after it closes. Here’s how each one works.<\/p>\n\n\n\n

Pre-market session: 9:00 AM \u2013 9:15 AM<\/strong><\/p>\n\n\n\n

The pre-market session runs for 15 minutes before regular trading begins and has three windows:<\/p>\n\n\n\n

  1. 9:00 AM \u2013 9:05 AM, Order entry (Phase 1):<\/strong> Place, modify, or cancel both limit and market orders.<\/li>
  2. 9:05 AM \u2013 9:10 AM, Order entry (Phase 2):<\/strong> Only limit orders can be placed, modified, or cancelled, and market orders are rejected. The exchange closes order entry at a random moment between 9:08 and 9:10. <\/strong><\/li>
  3. 9:10 AM \u2013 9:12 AM, Order matching:<\/strong> The exchange determines the opening price through a call auction and confirms trades. No new orders can be placed. Matching starts right after order entry closes, so it can begin before 9:10. <\/li>
  4. 9:12 AM \u2013 9:15 AM, Buffer period: <\/strong>Transition window before regular trading begins at 9:15 AM. No order activity permitted.<\/li><\/ol>\n\n\n\n

    This session helps reduce sharp price gaps at market open by collecting orders in advance and discovering the opening price through an auction.<\/p>\n\n\n\n

    Pre-open session for futures contracts<\/strong><\/p>\n\n\n\n

    Futures contracts follow the same 9:00 AM \u2013 9:15 AM pre-open window, with two restrictions:<\/p>\n\n\n\n

    • Only current month contracts can be traded<\/li>
    • In the 5 trading days before a contract’s expiry, only the next month’s contract can be traded in pre-open. <\/li><\/ul>\n\n\n\n

      Post-market session: 3:50 PM \u2013 4:00 PM<\/strong><\/p>\n\n\n\n

      After the regular market closes at 3:30 PM, the post-market session runs from 3:50 PM to 4:00 PM. <\/p>\n","protected":false},"author":65,"comment_status":"open","ping_status":"closed","template":"","format":"standard","meta":[],"ht_kb_category":[2847],"ht_kb_tag":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26157"}],"collection":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb"}],"about":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/types\/ht_kb"}],"author":[{"embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/users\/65"}],"replies":[{"embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/comments?post=26157"}],"version-history":[{"count":2,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26157\/revisions"}],"predecessor-version":[{"id":29867,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb\/26157\/revisions\/29867"}],"wp:attachment":[{"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/media?parent=26157"}],"wp:term":[{"taxonomy":"ht_kb_category","embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb_category?post=26157"},{"taxonomy":"ht_kb_tag","embeddable":true,"href":"https:\/\/www.samco.in\/help-support\/wp-json\/wp\/v2\/ht_kb_tag?post=26157"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
