Warp, let me add to the explanation given by pvz, regarding the ADX indicator.
You have three lines. The black line represents the trend. The +D1 line, usually a green line, represents the buyers. The -D1 line, usually a red line represents the sellers.
The line that is on top has control of the trend. So, if the red line is above the green line, the trend line may be turning up, but it's indicating the sellers have control of the equity or index.
You want to see the green line crossing up and over the red line. This would put the buyers back in control.
In using RFMD as an example, you'll notice the red line, the sellers, had control of the trend until the trend line reached the 50 mark. This was an indication that RFMD was due to reverse. As the red line dropped lower and lower, the black trend line also dropped with it.
