When Titan was at 3820 on the spot market, DEC futures were in 3890 range. It increased so fast, and when I could see, it was already at 4000. I was shocked, I couldn't believe it. I decided to hold it, because I could hold till the end of December expiry, and I thought it will crash. But it kept going higher. I squared of at 4200. There was no stoploss. My spreadsheet shows a loss of
-43780 in 1 single day.
I'm sorry, very disappointed with myself, that I could not follow the stoploss given by you.
