todays situation :-
dollarseptfut was at 66.6250
i had achieved a decent margin at 66.6000 itself .
however, i still was hopeful that it may go a little more up , however i was not ready to risk the 66.6000 position.
so i placed a sell limit order at 66.150 when LTP was 66.2500 .
i thought i would sell only when dollar comes down , but it sold immediately .
why so ?
