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.
