Investors generally three kinds of tools: toolbox, black box, and gray box when it comes to computer asistance.
Or as Alexander Elder puts it... "Toolboxes are for serious traders, black boxes are for people who believe in Santa Claus, and gray boxes are in between."
So, which group do you really belong to?
Toolbox has a whole set of tools for you to apply as you wish. A good charting program, for example, with a full complement of drawing tools, markers, flags, trends, as well as full set of technical indicators, RSI, Stochastics, Moving Averages, envelopes and bands, or even write your own, is a toolbox. You choose which tools to apply, and apply the tools your way. The tools do NOT force their views on you. They just process data, spits out some numbers / charts. You decide if they are good signals.
