Rahul,
Let me answer this from a psychological aspect. Some parts may sound rude to you & others but I hope you guys know by now that I can never mean that. I have to write this way to get my point through.
If you were to allow me to judge what you have done, then I would say that what you did tells me three things.
a) You don't have faith on your Index EOD system - If you had faith, then you would have closed the intra day trade today itself and booked profits on it. You have not done so to get peace of mind today. Markets don't pay anyone for taking easy decisions. Just remember that.
b) You are not disciplined - You are a system trader and the one thing system traders don't do is they never break their rules. You have taken a intraday system and now turned it into a EOD trade. Stick to rules. Either be discretionary or be a system related trader. Don't mix both.
c) Learn to Embrace Pain - You need to learn to embrace pain. Fall in love with red and it will start ignoring you. Which means, you will start to see more of green in your account. This is the most difficult part in trading and is very very hard to practice.
For E.g. - You questioned me on Tata steel today. Despite of what was going on and despite of excellent results, I did not break my rules. Over the weekend, I did not anticipate, I embraced the "probable" pain and I am still in my position. This is because I don't mind losing 'N' % tomorrow.
How you need to approach the two time frames is something I have explained in the previous post and hence you can refer that.
