As I promised earlier that I will try pre-open order in GROWW and let you know if is it working or not ? And how it's working
So I put 2 orders respectively of HFCL shares
1) on BSE at market price on 9:04
2) on NSE at limit price on 9:07 (at rs.90)
First order successful executed at market price on 9:07 at 95.25 which is opening price of stock , second executed at 95.58 at 9:15 but opening price of stock is 95.60.
For your understanding I am adding s.s of orders.
