# High % Risk and Compunding

Anyone tried using or uses high % risk?

I will be taking 20% of account to use for high risk with the aim of compunding (I may as well put my signature to use).

My account has 100:1 leverage and if I have worked it out correctly then to get a margin call at the point my SL is hit is given by:

SL/(100 + SL) SL = stop loss in pips.

So with a 25pip SL the most I can risk is 20%, with SL = 100pips it would be 50%, but using SL = 25pips, 100pip gain is 80% account and 50% acount growth with 100 pip SL.

Kelly's number gives the % to risk for optimal growth if you know the probabilities of win, loss, or breakeven:

Fraction to bet F = (R*W-L)/R(W+L)

average growth per trade y = [(1+FR)^W]*[(1-f)^L]

Account growth after N trades = y^N

R = Reward (as in 1:3 etc)
W = probability of win
L = probability of loss

Alternatively if you are going to risk a certain fraction, its easy to calculate the minimum W needed.

So if your W = 55%, L=45% then for R = 1, F = 10% and average trade makes 1.005 gain.

Why are people so reluctant to actually learn how to trade?

...all these magic formulas...

Good luck...I think at these levels of risk...ruin is immanent.....

But 20% of the part of the account you've apportioned for it. So what's your point?

Obviously the whole account grows as the 20% part grows, but the % risk on the whole account will also grow. I suppose its like starting off with a little risk then increasing the risk as you get more of the casinos money. Say the high risk part doubles, then 25% of that equals 8.3% of the whole account.

4% per trade is still rather meaty IMO

The best of British luck to you. I hope that it trades well for you. We are all cheering you on. Go team.

Keep us up to date on your progress with this trading style.

(I give it less than a week before it is a busted account).

This sounds like when my wife goes shopping and tries to explain how she's actually investing because the pile of overpriced tat she bought saves her buying greater quantities of cheaper tat in the future.

Hopefully your account fares better than when my wife's been let loose on ours.

20% is a bit much. You just don't have much room for error. With some luck and good timing you could probably get away with 10% for a while if you catch a nice run, but eventually you're going to get bit. Good luck, though. It would sure be exciting if you actually do it!

Fraction to bet F = (R*W-L)/R(W+L)
Where did you get that formula? I'm just wondering who couldn't figure out that (W+L) = 1

Don't you think you should scale down your size a bit? 25 pips is a fart in a storm.
