I know a few algorithmic position traders.... and it's got sweet nothing to do with high-frequency, or even day-trades usually. They have their algorithms, software they've developed to handle analysis, and get them in and out according to plan - I believe they research their target sector a bit, fire up their algorithm machines, and then manually execute (or at least approve their software to execute) the plan they had in place - and it's all position based. They know when they're getting out of any position, up or down - whether that happens the same day or in days or weeks, or months.
Lots of neat software, but not day-trading and not HFT.
