The problem is that we dont really know when it is the right time to do some trading.. it is just a nature thing, when you see a cheap price you are tempted to buy.. it is not because your instincts are telling you to do so.
'Doing the right thing at the right moment is the key'? I mean... no shit? Isn't the problem that it's impossible to know what the right thing to do is with any real certainty?
