There is no need to follow this 2% rule strictly because if a trader is sure about a certain trade, then he/she would miss the opportunity to win big if he/she trades using the 2% rule. One can go up and down this number according to his/her knowledge and experience.
I also follow this rule, but once in a blue moon, I risk a lot more than 2%, especially when I find a trade where I can make huge profits. I know it’s risky, but it doesn’t feel right to risk only 2% when you know you can make a lot more by risking more.
to keep manage 2% risk for all time is really difficult , because market is too much volatile and no one can predict the real faction of this market with certainly.
