you do not need a holy grail to be profitable.According to your incredible stupid idea, there are no profitable traders at brokerages.
a holy grail is 100% win or so i have i have assumed.
most profitable traders have win ratio of not more than 60%,if public literature on the subject is to be believed.
if you believe that traders who are consistently profitable have the holy grail then the holy grail does exist.
it is possible to be consistently profitable by reading the market correctly because no price action takes place without warning;
