Advantage of DQ order:
- Only the amount specified as disc. qty will get displayed in the market depth window of all trading terminals. If people see you have placed a large order, they will correct their orders to a price value before yours' so that they need not wait in queue. So it will take huge time, or your order may not get executed and market could go down.
Points to ponder on DQ orders:
- Its not allowed in PreOpen or PostClose session
- You need to specify atleast 10% of the order quantity, not less than that.
- Yes, as Nithin said, you need to type an additional number while placing the order :)
