@MuStrFc How exchange know to transfer stock from A to C
As A sold shares in morning and C takes position on afternoon, exchange can not link between A & C and direct trade doesnt happened them.
Exchange only takes from the order type which broker provides to exchange.
Also if there is such relation then how delivarable qty is more than free float shares and does it mean to today all QIBs, HNIs, RIIs and SH solds all shares?
Also some brokers like zerodha allow to convert order type to Delivery to Intraday and Intraday to Delivery, then how exchange calcuates them if someone changed from Delivery to Intraday?
All is that exchange only calculates from Order type which is provided by broker to exchange when placing order and order executed on exchange.
