I guess i have some explaining to do. A picture speaks a thousand words

.
Take a rising triangle, for example. I am not sure if this example is valid(i dont think so, but it's the main idea) Take a look at XLE(below)

Another example might be the chart of nasdaq. This one, i suppose is a rising wedge?

*I am in a rush for time, and the examples i raised may not be valid. But the main idea is that the upper line shows resistance, while the lower line shows support. So, when the price hits the line of resistance, it is likely to go down, unless it "breakout"(which i'll explain another time). And when the price touches the support, it will bounce back up, unless of course, it breaks down or something.
Usually, when the price breaks out above the resistance(on high volume), it is a good sign of a bull. And when the price goes below the support line, it is a sign of a bear.
