@fughe Demo accounts are not always worthless - it depends if a trading strategy is used or one is always betting the farm. If the first, then you should get almost identical trading results (assuming of course you're taking the same risks).
I agree that going for huge returns definitely adds unnecessary stress to your trading.
But, you have to remember, this is a test to have massive account growth and, in forex trading, a HUGE part of the trading is psychology. I have seen systems work great in backtesting, but almost no one is capable of trading them because they cannot handle them psychologically when applied to real money.
In a demo account, the psychological aspect is removed entirely. So, I still say demo accounts are useless when attempting to prove cases such as this.
Now, for nothing more than seeing how a system could theoretically perform....yeah, a demo account could be of use. But not to test real world validity. I suppose I wasn't very clear on that point. :)
Anyway, now you understand what i was implying.
Make losses, but always come out a winner at the end.
