    Registry and Microsoft Safety Scanner

    My advice would be to go to one of the good free help sites like the bullguard forum, and have them take a look at some of your files under the diagnostics they require. Or just pose the same question there. It usually helps to have a lot of experience in evaluating which keys are critical.

    SEC may Reinstate Uptick Rule

    Notice the 80A collar rule was put in place as a protection mechanism as a direct result of the 87 crash. Guess what other rule was simultaneously removed right before this debacle? Couldn't have picked a better combination to exasperate a crash if you wanted to. I'm sure it was just a...

    I can prove “Random walk theory” wrong.

    About the only thing you've proven, is that you do not understand what a proof is. If you would like to substantiate some of your claims (which are completely false), start by providing the exact data/instruments/stocks for replication, as well as the specific criteria for what qualifies as...

    SEC may Reinstate Uptick Rule

    ------------------------------------------------ Those "pompous asses" in academia have seen it all and made their voices heard over and over. You'd think that the regulatory agencies, with a myriad of the best financial and informational tools at their disposal, would also see it. It's...

    SEC may Reinstate Uptick Rule

    It's not so much that I advocate uptick rule, as I tend to agree with some of the points about market efficiency and distortions imposed by up-tick rule. The issue I have is with the methodology they used to argue that removal of the rule would have no impact on market volatility. If you go...

    SEC may Reinstate Uptick Rule

    Gee let's see... Our detailed and thorough research has without a shadow of a doubt demonstrated that the uptick rule removal and simultaneous removal of collar 80A (put in place after 87 debacle) would have absolutely no impact on market volatility. Now go back and look at a 1 yr VIX chart...

    economics cycles become shorter??

    In fact, my argument may be a bit clearer looking at it from this perspective. cheers.

    economics cycles become shorter??

    Not at all. In fact, the overall cycle length has been expanding, primarily due to the fact that expansion lengths are growing exponentially (see my other post: 'singularity is near'). The good news to think about if you are biased long, is that the contractions have been getting comparably...

    What could be a catalyst for a 20-30% rally?

    I don't know the exact answer. But, I recall during the 03 bottom, what started the market roaring was a series of earnings reports that were considered better than expected; starting with yahoo. I know I was rudely awakened on a few shorts, waiting for capitulation as all the (clueless)...

    Normalizing Neural Network Inputs.

    Thanks, although I'm pretty familiar with the basics. I am more interested in experienced based specifics that work for you, such as architecture, OOS hit rate, input factors, etc.. (as explicitly mentioned in 1st post). Or, almost as useful, would be what didn't work for you. Sounds like...

    Normalizing Neural Network Inputs.

    Interesting that the thread is a year old. However, considering the renewed interest in two threads, perhaps some of our experienced users can chime in on some of the following areas. 1) What training size and validation size sample sets have you found to be useful? 1a) What resolution are...
