  1. Ok, let's see the evidence and results of your testing.

  4. Anecdotal and has nothing to do with testing, statistics or probabilities.

    So test it, if it means that much to you. You have all the information you need. If you had done so a couple of months ago, you would have avoided calling a top 600pts too early.

  6. Thanks for the link. Edward Thorp is a pretty good definition of "edge". I heard him give a talk at a local APS physics conference when I was a physics grad student at U. Cal., Irvine. He taught there. My recollection is that at the time (perhaps 1985) he had made something less than $100 million but not by much. His book was "Beat the Dealer", about black jack. He made his money in the options market, with a new method of pricing them.

  7. Beat the dealer was about black jack. He also has Mathematics of Gambling and beat the market. The latter two I managed to obtain originals of from Amazon.

    "You have all the information you need" you are a two of a kind in your responses. if you can't present the answer you put the onus on the other person to disprove your remarks.

    Yes, it's up to whomever to determine whether or not the approach meets his needs. My results are irrelevant unless I'm going to commit myself to providing him with RT calls every day all day for the foreseeable future. And even if I did provide him with the calls, he'd be a fool to take them unless he had gone through an extensive verification process. In which case he wouldn't need me. Though I suspect that most traders don't even know how to conduct such a test but are embarrassed to admit it.

    Each trader has to decide for himself whether he wants to be independent or a Gimmee. A lot of people are satisfied with being Gimmees, spending their lives in trading rooms or scrounging for tips on message boards. And if they're happy with that, why not? Life's short.
