position sizing and volatility.

What methods do others use with regarding position sizing and volatility?

I have some systems that that look pretty good on paper, but if the profits/loses from the more volatile periods were brought more in line with the profits/loses in the less volatile period, it would look much better.

1-3 day holding periods. I don't use stops so I can't control it that way. I don't really like the idea of using the vix due to its directionality.

Any other ideas/theories that people could suggest would be greatly appreciated.

Thanks
