Mate, a word of advice.....when you want to know if some method is applicable, better by far than asking people is to do your own research and make up your own mind.
Asking questions sounds good in theory, but the problem is that it can lead to you getting so many different opinions that in the end you don't know who to believe and who not to.
Nothing beats your own research when it comes to finding out what works and what doesn't. Chart time is the key. Look at thousands of charts going back dozens of years. Become so familiar with a setup that it almost jumps off the chart and bites you, so that you recognise it instantly when you see it.
Find yourself a pattern or a setup you like, one that's simple and suits your personality. Become an expert in trading that pattern. Practice and practice and practice until you feel you 'own' that pattern and you can just about trade it in your sleep.
