I have passed on a lot of trading ideas to my friends.
From those examples i have come to know that for the same trading idea,
the money made will differ from person to person. Even if the stops and targets are clearly mentioned.
Some might even end up in losses in a winning trade.
Systems, almost all the systems are fool proof, provide people choose to abide by them.
I can bet wih my trading style you can earn almost daily, or even Pride's Intraday strategy(search for it here, its great!!).
Will you be able to or not is upto you. How conditioned trader you are.
How disclipined you are..
