How would my limits be blocked for market orders for Pre-open enabled scripts? And can I modify my disclosed quantity while placing an order during the Pre-open session?

Hi Pawan,
Every system will have its own mechanism to compute the amount of margin to be blocked for market orders.
I could only clarify how the NEST trading platform offered by Omnesys technologies blocks funds.
Margins blocked on NEST trading platform for market orders = LTP*Quantity for which order is placed
In case of non availability of LTP, the previous day’s LTP is considered.

I have a slightly different view on this. The margin for market orders should be calculated on the closing price of the previous day = Closing price * quantity
LTP for same day will not be possible because order are collected between 9:00 & 9:08 and no trading takes place here. Hence margin has to be calculated here based on the previous days closing price. And you cannot place orders after 9:08 hence LTP is now doesn’t matter.
And LTP of the previous day can be different from the closing price - hence I would guess that the closing price of previous day will be considered for margin calculations.
Coming to the 2nd point on modifying disclosed quantity - I far as I am aware, disclosed quantity orders are not allowed in pre-market session.

If you think he is correct, why don’t u upvote him 
Its little confusing!!
Is it the closing price or the LTP?
