    Interesting results in new markets

    Completely disagree on that statement. If anything you are penalizing over fitting by forcing the strategy to work across several markets. That is one form of regularization designed to combat over-fit optimization. The more you adapt it to a specific market nature, the more you likely you...

    what's the name of that stock (ETF?) that's like one of every stock in the market?

    Vanguard has a few broad market tracking products. VTI is a broad market (total stock market) ETF. http://seekingalpha.com/article/30316-a-guide-to-u-s-total-market-and-broad-etfs

    new power supply unit

    Agree with troubleshooting methods of prior posters (ex scat). It should have little to do with a supply change. Every power supply has regulated (i.e. close to perfectly constant) voltage sources. If for some reason, however, it was power starved (suppose you had 30w and your power wanted...

    Netflix/redbox killer

    I wouldn't go so far as to call it a killer. I've used it as an alternate streaming source for a long time (its integrated into most sony streaming media boxes) with few issues. The movie selection is a very small set of older movies (from the 80s to 90s) that is rarely repopulated and paid...

    Which strategies work, and which don't

    It likely refers to simple moving average based strategies (i.e. if ma1 cross ma2 then buy, etc...). Incidentally, in my experience, SR increases at higher frequencies ... unfortunately, so do commissions and slippage.

    Constructing an econometric model

    Before even choosing any model, I would start by looking at a simple scatter-plot and or correlogram to discern any relationship beyond noise. Once you've determined there is (or isn't) an existing relationship, you can move to the appropriate model. Here's a decent book on modelling...

    prob function combining continuous and discrete

    Binning will filter original histogram somewhat, but if you want to actually smooth it, you can look into kernel density estimation or knn smoothing for non-parametric distributions. Several free implementations are listed at the bottom of this wiki entry...

    prob function combining continuous and discrete

    I wouldn't really approach it by expressing it as a continuous function (or combination comprised of such). Using the guassian (or any known cont. function) PDF will not likely match your curve (particularly in tails and various moments). Finding a continuous function for these types of...

    How to Increase Firefox' default page zoom?

    I've had to deal with the settings issue due to aging and eye strain. Unfortunately, it is an add-on (firefox) -- however, I'm very pleased with it: Nosquint.

    Regression trees for predicting trade success

    @Hugin. Always good to hear your comments. BTW, I always meant to ask; did you get your handle from the bayesian software tool? @jcl. Seeing as you are a forex guy and looking at the types of inputs you used, here's a series of some slightly older, well-written articles you might find of...

    Regression trees for predicting trade success

    http://intelligenttradingtech.blogspot.com/2010/02/prior-introduction-using-simple-model.html Would love to hear your results. As noted by others, but put forth another way, sometimes it's not so much the appliance, but finding and preparing the ingredients that is the hard part. Dealing...

    Why do 5% of Traders Win?

    Good insights (all of the prior posts you made here), IMO.:) The only issue I have as a retail trader, is that while I agree there are many good edges present in much lower time scales (superior to higher, such as autocorrelation, for example), the practical issues, like getting filled, size...

    CPU usage haywired when laptop power unplugged

    Although I never observed that exact problem, I did have a similar one, whereby the backlight would constantly dim whenever I unplugged the laptop. I found there was a way to correct for this somewhere in the control panel (power mode?). So you might want to snoop around that area, at least to...
