BTST query

hello guys,

sorry, wrong thread but i need to know something urgently about BTST trades. Suppose i have 1 lakh and buy 2 lakh worth of a scrip to square off on the next day, can i square off the 1 lakh i bought with broker margin and take delivery of the rest for which i have the funds or is there an obligation to square off all the shares on the next day?

i am with sharekhan.

thanks in advance
