Is it possible to hold MIS buy share for 1-2day without change it in CNC category
MIS is an intraday order type valid only for a particular trading day. All MIS orders will be
automatically squared off at 3:20 PM.
If you want to hold your shares for more than one day, you have to compulsorily change it to CNC category before 3.20pm.
Please read this thread to understand more about the order types. You can also watch the explainer videos for the various order types here on the Zerodha YouTube Channel.
