Hi. My strategy requires me to buy and hold equity ETFs for a few days. However inorder to save on margin, I like to place MIS Buy orders and if they get executed, convert them to CNC.
#1 What API can I use to do this update from MIS to CNC?
#2 When the order gets executed, I get a postback call. Can I call this update API when I am processing that postback?
#3 Is there a timelimit by which the MIS to CNC conversion should happen? Like by 3PM or so? Typically when the orders are only partially executed , I get a postback by 330PM. Can I update the MIS to CNC status in response to that postback?
