扩大风险 (Scaling Risk)

Hello,

I'm considering running with a scaling risk strategy. Upto 5% http://www.trade2win.com/boards/imag..._surprised.gif I know that this is 4% more than I should risk on any trade but given my small starting capital It would take me an age to grow using 1% rules.

Winning trade = increase risk by 1% / losing trade = decrease risk by 1%

My risk profile will look something like the following over 20 trades: 10wins & 10Losers
1 2 3 4 5 5 5 4 3 2 3 4 3 4 5 4 3 2 1 1 (% Risk)

The basis of my plan is to be big when I'm winning and small when (not if) my system is taking a battering. I'd like your thoughts please and wonder if anyone else has/is doing the same. My plan is only to only pick A+ trades and not to get complacent when I'm on a roll i.e 5% and pick average setups.

Thanks for any input, good or bad to my first post.
Regards
Dan
