I took a look at the "King of the Mini's" trading log. (It's linked in a post below).
First of all, this guy(or gal) pissed away his/her account during the first two weeks of the month. You'll see the account equity was a mere $48.83 on March 14th.
He then re-deposited $1,200 (it took a week to do that-so he lost a week).
He then regularly WAY over leveraged his trades - some were 500k trades on an account with less than $1500. (not a good idea).
So, this guy actually posted profits of over 500% in just one week!
Yes, short-term results like this are possible, but I wouldn't recommend over leveraging like that. No offence to the owner of the account - I can only dream of those results - but he probably won't be around much longer if he keeps that up - the name of the game is RISK MANAGEMENT.
