I had mentioned the DMI in a Stochastics thread and got like 10 people mailing me about it, so I figured the best way to discuss it would be a new thread. Anyway, I use the DMI/ADX almost exclusively (DMI is the Directional Movement Index & ADX is the Average Directional Movement Index ). The only additional indicator I use is Nasdaq futures. I have used this theory for day trading for several years and I consistently make money. I am profitable almost everyday, although I have had a few ( very selodom) net negative days when you count commissions. DMI/ADX works great for any trading from day trading to swing or position trading. I combine the ADX/DMI onto one study. I make the ADX line white in color, the PDI line red, and the MDI line green. I use the PRO software offered by Realfasttrader. That software makes it real easy because it already combines ADX/DMI into one indicator. Although, I'm pretty sure most softwares out there also have DMI/ADX (it's very common), I think it's easiest to use when they are combined. This is how I do it: When white (ADX) crosses the other lines and is at the top and green (MDI) is at the bottom (red in the middle), it's a buy. White on top red (PDI) on the bottom (green in the middle), it's a sell. Often the simplest things work best and this seems simple and it is, but it works very good. I consistently make between .02 -.05 cents on 2000 - 5000 share trades. I usually go for more around the open (maybe .05-.10 or more). I ONLY trade widely traded Nasdaq stocks, like CSCO and INTC.
