The 3rd SELL Signal Failed with 50 - 60 points up move, due to the sudden pumping of the money in the banking stocks.
With proper expiry planning any trader would have been profitable today. In my previous its mentioned to be cautious.
Buy Signal Analysis:
1st SD Today Expiry Options - 26700 PE is at 36 Rs During 1st Buy signal - If you have written the option, Now it is a 3.8 RS
Sell Signal Analysis:
1st SD Today Expiry Options - 27000 is at 20 during the Sell Signal - If you have written the option, Now it is a 12 RS .
So In total you would have earned a 40 Rs profit in a Range bound Market like today,
Even if you not traded any Option strategy - The Time Decay on the expiry day helps you to win.
I am not telling something new here, you have to understand how the Underlying is distributed among the UP TICK and DOWN TICK
