Quote from marketsurfer:
Thanks for the post logicman--- it lays out the fatal flaw inTA brilliantly. TA practitioners always refer to "probabilities" "probable paths" as you say. Probabilities can be quantified by common statistical tools. TA can't be quantified , therefore there is no greater probability of a certain pattern, price, volume creating a predictable move in a given direction than any other Move or series If there was, it could be defined and quantified in studies. Once again--- how many moves or series of move s in one direction increase the odds that the next move will be inthe same direction ( trend) ? Impossible to answer-- therein lays the absurdity of TA and it's sister "trend".
No, it can't be quantified in the sense of coming up with a single number like you seem to want. But, there is an underlying "logic" to it (that's why I chose my name, because this "logic" is the basis of my analysis). A "trend" is really 3 segments, a beginning, a middle and an end. The necessary "logical" features of each of these three segments can each be categorized and rules to identify the first moment when a "beginning" might be occurring and when the "middle" becomes "the end" can be put in place. In my mind, what this "logic" does is enable market action that seems different on the surface to be comparable on as much of an "apples-to-apples" basis as possible. To me, this comparison is the crux of identifying trading opportunities. You almost have to look at the market as much as a philosopher would as you have to look at it like a mathematician would. Fortunately, my academic background includes a lot of both, so I can do this relatively easily.
Once the logical requirements for the beginning of a trend have been met, there are two potential outcomes. The first is that the trend does exist and result in a profitable trade. The second is that the trend exists, but is too weak to result in a profitable trade. This is the uncertainty inherent in my analysis.
There is a third type of trend which begins without meeting the logical requirements. However, these trends can be identified by the fact that they don't meet the logical requirements. They can therefore be avoided and the trader remains out of the market during these types of trend. They don't result in any trade triggers, they just sort of play out with me on the sidelines. All it takes is a little patience to wait for them and then see if they impact the analysis for the next potential trend.
Within those trends, there are trade management rules, some of which come into play even before the trade is entered, as a way of avoiding "false positive" trade triggers.
It's all very tight and logical and, most importantly, profitable.
So, the reason I rewrote the definition was so that it would fit what I do better.
In the end, I have to either believe you or believe my own experience. That's a debate you cannot win.
