TimDog,
We have been following GROW for awhile, since Sept or Oct 2006 for me and maybe longer for everyone else.
After following it for so long you begin to know its habits. Take a look at the 30 min chart, and compare that to the other stocks on today's watchlist. Look at the 5 min as well. GROW as well as many of the other Hershey stocks in DU, on a buy watchlist for the day, and about to pop up, all seem to exhibit a certain 5 min pattern. The pattern will vary depending on the indicators you are using as well as their settings. I have the ability to adapt my indicators via a neural network, as well as via an open source data mining tool I use (WEKA), but the standard settings on any of the indicators mentioned here (hint: read the journal) seem to work as well.
By the way, you don't need any special tools with the Hershey method. You can visually inspect any chart and see what Spydertrader is talking about in a matter of seconds. Software tools just help with number crunching and finding patterns in a great deal of stocks.
