Going for big money trades generates too many losses. small accounts cannot withstand them and die a slow death suffering loss, after loss waiting for the big one to recover them all and make something.
Try adding up all your wins and losses, and divide by the number of trades you did over all in a month. You may find your average win is only like $65.00 anyway. What difference does it make if you have a big win, when the other 60% chew it up into a little over all gain?
I may have lots of little gains, but when you add them up, I bet they are as much as you one. I trade entire trends, one slice at a time. If you made on a big move, You can bet I did too...only without all your losses.
