I have made it many times on expiry day what is double i dont know
But I know only atleast 10 times but strictly only during expiry and in option trades
Eg.
Suppose Buy put of 0.45 rs x 5000 qty of just below in the money taking to consideration having a brokerage of rs 50 buy and rs 50 sale per Lot (50) qty so net margin involved is only 13500 Max inc of his selling brokerage and other charges now if nifty falls 140 pts from that buying range put will trun atleast 15-25-40rs max so my aggregate buying price inc of all charges was 2.70 and my selling will be 27 rs so my net investment will be 13.5k and now my gain will be 1.35Lakh minus my 2.25x5000 charges = 11250 and total earning is above 123750/- which is x 9.16 % of your margin thats y i told i dont know what is .5 times i know 10 times minimum
i have even seen put of 1.5 rs truning 15 and holding it at that level and then busting at whooping 180 rs and giving a day high of that range so nothing is impossible esp on expiry and haa i also say that on normal days if we know the trend we can also 2x our margin but only if mkt have a good movement mkt should go somewhere and no sideways
Happy Trading
