I like to keep it simple. Look for historical highs and lows, set your levels, buy high, sell low! For all the newbies to trading, keep it simple, buy high, sell low! don't think too much about it 
keep it simple? it is sounds like you are gamble to do trading here ,you need a lot of sources to decide place your buying / selling position ,
otherwise it is just another way to gamble that is what i've learned ,
trading are not as simple as people said like buy low sell high!
As Albert Einstein once said, everything should be as simple as it can be, but not simpler. In other fields and among other ranks, it is known as the KISS strategy ("keep it simple stupid"), which basically claims that most systems (including trading) are better off on the whole if they are kept simple rather than sophisticated. Superfluous complexity of trading methods might certainly make you believe that it would somehow help you trade more profitably while in fact it could actually work in the opposite direction...
And eventually bring you heavy losses
