Ultimately, the best trading strategy is the one that best suits your individual needs and goals.
Exactly mate and invariably you're trying to say that having a trading strategy doesn't really matter as long as what you follow truly works for you and I do agree with this too but I think at some points after following so much signals, I think one might be learning this things gradually and people pick more interest in things that bring money and by so doing, they might develop their own strategy and whatever the case might be, it is always good and better to have your own personal strategy so as to take full possessions of your trade and full responsibility for your trades as well.
You are right mate,trading strategy is your own personal way of approaching trade,and bringing out good result on your own.different person's have their own different approaches to trading,and those approaches can either be achaic,( old ) or new.When one uses a method he has been using before and has been working for him to trade,and it doesn't seem to give him a desired result,it is good to change method so you won't be on the losing side.The approach I was using before is different from the one I'm using now because trading strategy has to be dynamic for it to work effectively,anything that makes it just one,then there is every tendency that the individual will not be making progress in his trading business.
