I'm not a chartist, but I'll weigh in...
I think it comes down to how wide the interest is in stock. When you have lots of trades from across the spectrum, you tend to get a sense of the sentiment around a stock ( as in stats, the more samples you have the better your estimate ). Then I think analizing charts has it uses, but only in conjuction with all other info. A good example would be JPHC which has alot of eyes o n it. After a runup on news, it settled down to a base of 0.001 and by looking at bounces off of that with volume, one can infer that it will continue to stay above that as it consolidates. Use that as a basis for further DD, then pick your entry. In short, one can cautiously use charts with quality pinks, in conjuction with other DD I believe. For the most part though, what goes up will almost certainly come down in short order in pinky land so charts are of little use.
all IMO
