Appreciate your posts. Yes, you are right, the market conditions are extremely varied and not every best strategy can cope with it.
Well, it's quite an interesting question, which can be really confusing. I am of the opinion that sometimes even the most successful strategy can let down one day and then it needs to be changed urgently.
I agree with you. If something goes wrong, it's time to out of the box Personally I think that there is no eternal strategies that work equally good ll the time
