Allan,

> In my "Encyclopedia of Chart Patterns" by Bulkowski, he says that the H&S pattern reaches the price computation only 63%....<

Also, note that he says "reaches the price computation". Does that mean that there are instances where the trade wins but the measured move is not completed?


You make a very good point here. I'd be interested to know the statistics if anyone has them. If, for example, the probability of reaching 75% of the "measured move" were in the range of 80% or more, that would make a compelling case for acting on the breakdown, but setting your sights on a somewhat smaller move before taking profits.

I'd love to see a histogram of frequency of hitting price levels from the neckline down as a % of the predicted move. I suspect there might be a relatively high # of reversals just below the neckline (i.e., failed breakdowns), followed by a declining frequency before rising to give that 63% at or below the target.

Allan,

I guess everything is relative, but 63% is only slightly better than a flip of a coin (50:50) when speaking of pure probablity.

I have discussed the issue of probability on several occassions and I feel that if the time element is reduced which in turn reduces the number of variables, then probability can increase, keeping the same parameters of the predictions.
