One blunder mistake I did, allotting only 1 Lakhs initially for derivatives. Actually till Feb 09, the lot sizes in futures were very less and till mid march 1 lakh was sufficient to trade future scrips.
But due to recent rally, and increased lot size I failed to took positions in Essar oil, suzlon & Unitech. Even if I could have taken, position, even a little move against my position should have lead to square off my positions, due to lack of margin.
Now when I have increased the margin, I shall be able to play multiple favourite scrips in futures, instead of options.
