Sluggo, this is my point precisely. I agree that Sharpe is not a measure of risk itself however it is what is provided to us by CTA’s to make a decision about them. What measures of risk does the typical Barclays CTA report actually provide us with? Once again I argue that drawdowns and standard d...

Yes LeapFrog, my point is more directed towards evaluating CTA’s. Indeed I have all sorts of additional measuring tools available to me in my own systems trading than I do if I’m selecting a CTA. And by no means did I ever imply that MTE was the ONLY tool one would use. To me it’s just a “qu...

Where the margin to equity ratio is particularly useful is when evaluating CTA’s. The reason for this is because most CTA’s don’t report their portfolio heat; however they do report their MTE ratios. I know in my own trading my portfolio heat and margin-to-equity ratio come pretty close to bei...

How to SPEED UP simulations by 2 to 50 times (or more)!

Sluggo, That’s not really it. The way I am doing things is quite a bit more involved than that (not that complicated is better!). However, thanks for taking the time to read it and comment. My goal was simply to stimulate thinking on the subject and it seems as though it did that. I know personall...

Leapfrog, These are precisely the kinds of scenarios that MC simulations do a great job with. Assume that on average your daily percentage fluctuations are plus or minus .75%. Lets then assume you were in OJ the wrong way today and this caused you to have a -3% day. What the Monte Carlo will do is r...

I can’t help but being left with a lingering feeling about this whole discussion. Trading futures is not a place to try and figure out how to have certainty. It is where RISK TAKERS exchange UNCERTAINTY and potential losses for the chance of a profit. If you’re not walking into this knowing full...

Bari, No question scenarios like those happen all the time. I have probably run tens of thousands of hours of analysis over that very data and I would assume any serious traders here have done the same thing. In my case what I need are specific tools . At this point in my trading having the obvious ...

Forum Mgmnt, We are not in disagreement. I did not say, "This is the way to determine account size"." What I said was (paraphrasing) "If you're aggressive and you're looking for a strategy to maximize returns by using a tool to attempt to measure a maximum drawdown then here is an idea"." I think yo...

Tushar S. Chande has also created a formula that attempts to predict maximum future drawdowns (1). It is primarily derived from average daily volatility. Personally I think the formula is too conservative, however, I think the real value here is the understanding of how critical daily volatility is ...
