Are you kidding us?????
How can you average down to 40?
First, you Bought several lots of 8100 CE December at 286/-
i am assuming that your several lots of nifty as 10 = 750 initially
=2.14 lakhs
You averaged down to 186 by purchasing at 86
To average down, you have bought another 10 lots = 750
My assumption of 10 seems true
Holding 1500@186 = 2.79 lakhs
Now you are saying you average down to 40.
Hoping you should have purchased at 34(current price), you should purchase 500 lots that is 37500@34 to average down to 40.
Did you really purchased so many lots?? If so, it is one of the worst trades ever.
