How much should you risk?

The amount to risk should be tied to the frequency and degree of system-related drawdowns. No one is right 100% of the time, and too high of a risk would wipe you out with variance, even if your system exhibits long term profitability. Low risk enables you to survive moments of bad variance.
 
You told that you risk 15%, why? I don't think that you are a long-term trader. Don't you take such a risk too emotionally? I'd worried a lot if I risked such an amount of money. If we talk about sums, it's $1.500 from $10.000. You can lose them at once... I can't cope with this thought :)
Surely, when I have long-term trades, I never risk so much. But some risky and short-term ones have brought good money to me, why not? I understand clearly that if I lose it'll be only my problem. That's why I don't do such tricks very often.

Oh, I see. I thought you are just another newbie who's going to blow his account in the nearest future :D
Sorry, man!
Probably, you are just more risky than me, cause I can't allow myself to face such big risks in my everyday work :)
