Actually most of the trading in stocks is driven/directed by quantitative funds where the decision to buy or sell is based on computer models(i.e. technical analysis). That said I've made myself look silly a couple of times predicting what PTSC would do based on technical indicators. TA hasn't worked for PTSC because Lincoln/Swartz selling distorted supply, always offering up more shares than could be absorbed at the time. I don't think TA is telling us anything yet and even if indicators seem clear, experience teaches that they can't be trusted with PTSC
