a) I never made a claim about frequency distributions (not even sure what you are referring to here) b) One can cluster future possible outcomes and attach probabilities to them of occurring. One can indeed also attach probabilities to ANY future possible outcome via a probability distribution in a continuous realm (as opposed to discretized steps) c) your assertion why sometimes normal distributions are used is incorrect. They are used because they sometimes reasonably well approximate the true distribution of future events, but most importantly it is used because they greatly ease the mathematics behind them, especially in options pricing theory. d) Without probability concepts one would never be able to accurately price and trade options, for example. In fact everything in options theory is based on measure theory that is intricately linked to probability theory. e) It is not true that it "has been proven that a normal distribution does not apply to market behavior", as pointed out above, it does approximate market behavior in some cases and in fact much more sophisticated distributional models are used than normal distributions in other cases. f) your cynical comment re "convenient probability distribution choice" is somewhat mislead; in fact convenience does not preclude accuracy. Risk-free pricing is an incredible convenience and it at the same time leads to laser sharp and accurate options pricing, where closed-form solutions are available. g) Your comment of William Eckhardt re trading size has nothing whatsoever to do with probabilities. Frederick, I have huge respect for your laser sharp line of reasoning and political stance in P&R but judging from your comments to which I reply right now, this topic is maybe something you don't want to get onto too thin ice. I get the very strong impression that this is not an area you earn your daily bread with, but others do (wink)
I never talked about "past" price movement. So care to enlighten us what "valid" TA is? I honestly like to know. I believe the biggest problem in this whole discussion is the improper definition of TA and that not everyone agrees on the basic definition.
so, again you refuse to share with us even a single example of what you resort then to "valid" or "modern" TA? So far it is impossible to learn from you even though I make every effort...
Exactly right, but I doubt 'Inspector Javert' will ever give it a rest. He seems to derive some sort of satisfaction from it -- hard to understand... but I'm not a shrink!
Well, truth be told, brokers profit from transactions--TA is a good way to get the clients churning their money. When I say institutions, I am talking about those funds and groups who need to profit to survive not "induce clients" to trade. There is a huge difference. AND THIS DIFFERENTIATION IS THE FIRST STEP TO UNDERSTANDING HOW MARKETS REALLY WORK. peace, Hampton
a) I think a lot of people who think they are using "probabilities" confuse the two. b) Say what? c) Yes, they are approximations, at some times better than at others. That is why they require a wider berth. Because in additional to their only being probabilities, they are also not accurate representations of those probabilities. d) You got me there. I don't trade options, and couldn't if my life depended on it. I understand that the theory relies on a normal distribution curve, which is an approximation of actual market behavior, and that some people are better at gaming it than others. But I am utterly out of my depth here. e) "Approximation." Wider berth. Balance of probability. Less precision than the numbers would suggest or imply. f) Options again? I know nothing. But I'm guessing that your "laser sharp and accurate" reference is fanciful. g) I said "in part." I understood his point. But as it relates to this discussion, you cannot overlook that sizing is based in part on "probabilities" of outcome, which rely on rough approximations, and that if you play it too close to the line, you're playing chicken with the gods. Again, safer to go with "balance of probability" rather than illusions of precision, allowing more room for error than the "probabilities" would suggest. As I said, I know nothing about options. I'm not a math guy; I barely got through calculus at school. And though I studied up to intermediate level stats, I finished school in the mid '80s. As for trading, I've managed to make lunch money and occasional bus fare in the markets, but I play to my strengths. So TA as I define it: using past market data to arrive at trade timing. Oh, and all kinds of arithmetic.
