I've been using the one @

to test out diffrent trading set ups. It's pretty cool for testing out theories rather than risking real money.
Right now I'm testing out the $3k and %3 gains to a million in 200 trades idea. I think it can be done but but you have to take your time with it. Pick out the trades and only do about 40 per year. This way you can limit the risk and take your time with thje trades.
