It seems odd to me that all winners are less than 1R for a system with no profit target. Are you using a pre-supplied system or a custom trading system? Another thing that jumps out is the Expectation is 0.0 and Average Risk Percent is N/A. There could be a bug in your code, data, or both. With an ...

As a staunch libertarian of the Rothbardian coterie,I can relate to your issue,which for me carries not only a monetary,but an ethical value as well. While taxation is a question of morality and ethics, its greatest impact is mathmatical. Simply compute the difference between $1 compounded (once) a...

Thank you Sluggo, much appreciated. Yes i found the mini Eurodollar contract. Unfortunately i couldn't find anything on the 10Y note or even international Bonds and rates. There is a mini Eurodollar that trades on CME/IMM, but if you take a look at it you will notice that it has severe problems wit...

There seems to be an underlying assumption that past performance (from which Sharpe is computed) is indicative, or highly correlated to future performance. My testing has shown me that this isn’t the case. Jack Schwager drew similar, (but not identical) conclusions years earlier in a similar stud...

Well, Ray is trading stocks with some kind of fundamental filter. This sound very different from what we usually discuss here. Then he said: "How can you work 3000 trades every year? I try to keep down numbers of trades at a max of 500 per year." So, he his using Stop and Limist orders. T...

STIRs are somewhat special cases since the notional value of the contracts are generally very large in comparison to its volatility (or margin). It's "easy" to ramp up a very large notional values where "normal" volatility-based risk measures would indicate a "small" r...

Re: What happens when your porfolio correlates to 1?

One concern is the robustness of this rule. If we want to reduce position size if vol > x% and this rule only is triggered 10 or so times over the life of a test, is it something we should hang our hats on? Although perhaps we are erring on the side of caution if we do... I believe you've hit an im...
