Selling CNC Holdings

In how many days can one liquidate a CNC holding.
I created a position on July 2nd.
I sold the same number of stocks on July 3rd, but the same amount is still reflecting in holdings.

You can sell your holdings even on the same day(even if it is CNC).

@Puneet : what you did is called BTST which is allowed in all the shares with an inherent risk that if your purchase of 2nd july is not delivered as per schedule by selling broker your sale of 3 july will go for auction /square off as the case may be.
some broker do not permit BTST in T/S group of shares.
