First, find the lowest point of the pullback to determine the “stop out” point. If the stock declines lower than this point, you should exit the trade in order to limit losses. Then find highest point of the recent uptrend. This becomes the profit target. If the stock hits your target price or higher, you should consider exiting at least a portion of your position, to lock in some gains.
This part is all up to you. There is no "line crossing," "arrow appearing" or "a small voice telling you to buy now!"

Using our example, the Volume indicator shot up drastically meaning that traders are getting in on the action and thus driving the price upwards!
When it comes time to take profits, the swing trader will want to exit the trade as close as possible to the upper or lower channel line without being overly precise, which may cause the risk of missing the best opportunity. In a strong market when a stock is exhibiting a strong directional trend, traders can wait for the channel line to be reached before taking their profit, but in a weaker market, they may take their profits before the line is hit (in the event that the direction changes and the line does not get hit on that particular swing).

Sincere interviewed professional day trader John Kurisko, Sincere states, Kurisko believes that some of the reversals can be blamed on traders using high-speed computers with black-box algorithms scalping for pennies. “That’s one of the reasons many traders get frustrated with the market. The timing is not like it used to be, and many of the old rules don’t work like before.” 
Once you have a specific set of entry rules, scan through more charts to see if those conditions are generated each day (assuming you want to day trade every day) and more often than not produce a price move in the anticipated direction.
