And to piggyback on what Hlm said, if you do use indicator(s), make sure to find ones that are dis-similar in what they are representing to you. In other words, you do not want or need to almost identical oscillators.
Bollinger on Bollinger Bands talks about that in his book actually.
I realize, like hlm, that most consider indicators to be voo-doo or lagging, or whatever you want to call it, but they can be an aid to a trader looking for that one little vote of confidence.
The biggest concern you have to have when using any indicator is what does it look like when it fails (usually trend day or range day) and how will you shut it down when this happens.
