Tom.....
I believe the answer is fairly simple and straight forward.

#1--Any single trade at any point is a 50/50 chance of winning - No Less -- No More
#2--If you have developed a system that over 10 years produces 55% returns, then
you have already determined it's rate of success.

To determine exposure for any trade:
#1--$50,000 ÷ $2,500 = 20 x 55% = 11 contracts or $27,500 at risk on any single trade
#2--As the system produces gains your number of contracts will increase.
If the next time you traded your holdings were now $125,000....
$125,000 ÷ $2,500 = 50 x 55% = 27.5 contracts.
#3--Money management plays a part in retaining gains and a % of those
returns need to be taken out of the account.

If your system produced 70% returns:
$50,000 ÷ $2,500 = 20 x 70% = 14 contracts

Now...if your system can determine between good-bad-superb trades....then one could
develope a method of fading the number of contracts for good-gad-superb signals.

I don't believe it's much more difficult then this....

#1--If you wanted to be more careful use 45%
$50,000 ÷ $2,500 = 20 x 45% = 9 contracts
#2--Even more conservative....one would only trade the 5% that was
over the 50% success rate in this case 20 x 5% = 1
But this would be hardly worth it.

I'll look at this in a few days and see if I still agree >smile<
