When you are considering trading a stock, it is important to identify which direction the stock is trending. When a stock is in an uptrend you can do this by drawing a rising trendline.

This trendline will act as support for the stock, and is a good place to enter a buy order. When the stock breaks below the trendline, you sell your position and move on to the next trade. Check out this article for more specific entry and exit strategies.
