Hi and Welcome Im pretty much new to this forum but I have over ten years experience in trading Forex and U.S Stocks the best place to start is with youtube as everything is pretty much found there as for free resources but soon you will also realise that you need to work on your psychology because at the end of the day we in the business of decision making not trading. So get good at making decisions ahead of time and trading will be easy. Check out a guy called Mark Douglas he passed away but his material is GOLD!!
The best strategy is to try and make mistakes in a demo account, it is also important to know all the basic concepts of forex such as pip, spread, lot, etc, etc.
try Bollinger Band
google it to find more
there is no indicator that is the best
or strategy that is always profitable
so look also money management !!
