Those pesky computerized trades vrs. day traders

I had in interesting lunch discussion regarding day traders vrs. computerized trading. Most day traders tend to respond to technical analysis later than computerized trading. For example, take the slow stochastic analysis method. A buy signal occurs when the pk line rises above the pd line. However, what causes this to happen in the first place, and how likely is it to happen? We can use the stochastic efficiency ranking that I mentioned in yesterday's blog as a ranking of likeliness. As for the causes, what if we ignore this question and look for points where this is very likely to occur, for example when the pd value has decreased for 12 consecutive days of more and when the pd's rate of change will be less than 1, as determined the the rate of change of acceleration of the values change. That's a mouthfull... These stocks would have been picked at close of day 8/9/2007:

If one were to purchase $1000 of each stock without going over $1000 including a $14 fee per trade, the total cost of stocks would have been $26,385,73 These stocks made a profit of 3.0% in one day. I'll continue to monitor stocks on this scan and likely trade one or two every now and then.
