Rahul,
Seeing your posts for the last few weeks it appears that you are bent upon to destroy the thread of Sudoku. I am coming to this thread for the last three years and never traded these levels. Still after coming to the TJ I will come to this thread first. The question is not whether he is giving up or down or he is changing it during the market hours or after market hours. If you watch NSE option data there will be huge change during after hours and market hours data. Whether they are changing it after seeing your post. I am visiting this site since long and I do remember many veterans like Saint, Ashish, CV, Sunil, RJ, ST and Sudoku. Do not remember any significant contribution from you.
Everyone is having his own set of rules for trading. Sudoku is giving his own. My feeling is that very few may be trading just these levels. I mean alongwith these levels they may be having some more criteria to enter the trade. Instead of criticizing some ones method it will be better if you contribute some thing good. Whether he is good or bad in analysis or he is changing levels 10 times during market hours why should you bother? or why should any one bother.
I am having an impression that you are jealous of this thread and not the levels of Sudoku or it may be some thing personnel. My advice If you do not like it leave it dear. Matter ends.
