Consult ur own brokerage : Trying to contra to the maximum time limit possible but here's a guide

Answer to Questions below :

If you wish to contra,
but cannot do it by T+3,
it is possible to stretch another 2 days,
ie, max D+2 or same as T+5.

Note a contra is about the same stock.
Buy, sell are separate contracts,
so the two cannot be amalgamated.
But if by D+2 you still have not contra'd,
you must pay for the shares by eps on D+2.
If brokerage fails to receive the funds on time,
shares will be force-sold.

Hence, if you have not paid for the shares by D+2,
you cannot sell it yourself the next day
(from D+3 as it will become a short sell)
since the company would do the force sell for you.

Try to avoid going into D+2
as any problems will result in force selling.

Question :

Is contra still applicable longer than T+2 days,
ie after that, or more than T+3 days?
or even just before action by brokerage,
ie due date stretched to max.
