The reason I say that is I think if you take any chart and compare the red candles to the green candles it will tell you the trend. On a bear chart, the red candles should outnumber the green candles and vice-versa on a bull chart (at least that is my theory, I have not written an MT4 indicator to compare the two YET but I intend to as a tribute to my past blown out accounts lol).
So if that assumption is correct, if one were to play the probability percentage to your favor just like counting cards while playing blackjack at the casino then long term you (theoretically) should come out a winner.
