Degrees of Freedom

Discussion in 'Strategy Building' started by mahras2, May 14, 2006.

  1. Do you have a specific market you use your scalping method in? Do you own or lease a seat at an exchange?

    I scalp the ER2 contract, and I am often curious how many traders on the Elite boards own or lease seats. I bought a GEM seat because it was so cheap, and saved me a considerable amount on commissions.

  2. My next step is UBS and a Bloomy...I just got to get the right offer. I will move anywhere and do anything..I am married (one time) without kids, a homeowner and 47 years old without a degree...so what do you think of my open mind? Anything is possible and I want to be there. Trading is my life's work and any trader is a friend of mine, even though it is dog-eat-dog :)

    not to brag...but I have turned down three offers. hey... I trade my own money and can wait for the right one (I believe either way I will be a millionaire, just that opm might make it faster getting there)

    I call it scalping, but I am arbing...

    P.S. Not only can systems be the "invigoration of freedom" through their definition of discipline, so can lifestyle and outlook...

  3. Ya mean of course for them ego-tripping wise guys. :D
    I kind of wondered how come ya hadn't yet thrown string theory on your heap. There it is.
    :D

    super string and trading are as related as apples and iJustBoughtMyFiveYearOldDaughterATelescope.

    Yes, but very few have the training to do it. It is not that people aren't smart, it is that they simply don't have the training.

  6. This is a tough discussion to deal with.

    Bounding the discussion under the five issues you wish to be handled is a remarkable and adroit consideration.

    1. Optimum # of degrees of freedom (DF's)
    2. Play with the range of DF's,
    3. Balancing Df's and/with curve fitting,
    4. Optimizing extracting profits, and
    5. Dealing with change (markets) over time.

    I extracted 28 comments of respondents over the last 8 pages (See Word Attachment) which scope and bound the discussion heretofore. They bound the opportunity to four levels of performance as depicted by 8 persons, five of which are actual practitioners of your scope of inquiry.

    The solution you need lies outside of the constraints imposed by your respondent's general approach. Their Sharpe ratios scope and bound the solution they assimilate. What they offer is an automated speculation box whose guts is based on the maths of the usual stat and prob theorems. Too bad.

    I spent the time to deal with what is required to replace the limitations in the collective response you received. The literature that parallels this commentary is not replete mostly because it deals with money and that makes it kind of religious, worshipful and mystic.

    So there are two classes (kinds) of black boxes to deal with this tough situation. They are incompatible.

    My results are.

    1. The optimum DF's as inputs are 6 containing four correlated pairs deploying 5 of the 6. Four output DF's emerge.

    2. When you play with the opportunity a serious choice must be made early on. probability and statistics type math has to be dumped because of limitations of performance. The alternative is more complex and elegant. Five throughput stages are imposed between the input and output stages and interim DF's are created. The stages steer and focus the DF's to deal in a timely manner with the everchanging complex opportunity. Bottom line is a nominal 70 DF's (not concurrent) having 61 displayed signals.

    3. It is required to take this off the table. This is accomplished by changing mathematical basis of handling everything using a different functionality. The goal does not turn out to be balancing but, instead, to achieve efficiency and effectiveness of extraction in harmony with EMH. This is probably the basis for most disguntledness of the B people here.

    4. The range of Sharpe ratios of the four levels represented here by respondents is well below what is possible and so far you just have the conventional standards represented vaguely. To shift to Sharpe ratios that meet the potential offered, the alternative maths required make use of "drawdown" as an opportunity instead of an econometric "substitution" effect. By eliminating this probability and statistical "trap", the ratios go to the "too good to be true" range.

    5. Taking 3 off the table contributes greatly to not being "locked in" to the contemporary scene. One of the keys to this is to consider the DF's data flow in the context of the system of numeration used. It appears that by deploying a "phantom" base for explanation purposes is most helpful. By defining an order of magnitude with 5 symbols you have the equivalent of a base five system in operation. This nut will be very hard to crack by most. By changing bases numerically the blow up potential of a large number of DF's is avoided.

    All of the above is about 15 years old meaning it has been in use since prior to the invention of the eminis.

    I have written this stuff up in an extensive paper by culling my experience and the associated information into the five categories you suggest. I don't expect my comments to generate any discussion; if any facets are of interest, then I will continue.

    As has been seen in financial history, things change not by osmosis but by change of concept. The automated box the respondent group is in has limitations that are not going to be resolved by iterative refinement. It is more a "sea change" type of fix that has to be put in place. The current purveyors are going to be very persistent and maybe frustrated but that is how it always has been. The vacuum tube was replaced by the transistor and the transistor was replaced by the chip and the chip will be replaced by nano tech, etc... That is how it is.

    You can use the attachment to collect the situation. I just plugged the citations into the paper I have here as a way of pointing up the contrast between the paradigm here and the successor paradigm. The successor paradigm is based upon risk minimization instead of what you see here.

  7. Yeah, I was just using it as an example of something complicated that the general public kind of 'knows about', but which is very complex so they cant really understand it.

    Are you sure? How would you know?

    I probably know 50x more math than you do and it is not close to being clear to me.

  9. Nitro, I'm not being facetious here. But I'd be curious to know what types of math you studied, and whether you got a degree in mathematics, or taught yourself?

  10. Here's the thing. I won't pretend to compete with you on issues of math and physics. I was a poor physics student although I did manage to get by in math with most of my dignity intact. Against my questionable background in these sciences, I pose the following questions. How do you propose to use mathematics to predict human behavior? Market movement is the collection of human behavior, which is more akin to a social science than a pure science. How does advanced math or physics successfully effect a crossover from a pure science to a social science without losing much of its efficacy in the translation? Economists are known to use highly advanced mathematics in their models. How good are they, as a group, at predicting market behavior? Perhaps it is due to my admitted ignorance of the nuances of these sciences at an advanced (or even intermediate) level that I cannot imagine how either can be used in such a way as to enter the market at a point of relatively low risk and potentially high reward. Frankly, I am not even convinced that there is a valid theoretical basis for it. Please advise.
