The next thing you need to do is know how much money you are going to risk on the trade. When you enter the stock trade you need to make sure you have an exit strategy and have set your stop loss. A successful trader will use percentages not money gained or loss to analyze the trade. You can figure this by what percentage you are willing to risk and how much profit you want to make on each trade. Somewhere between 2 and 5 percent is a good starting point.
When you have all your parameters in place it is time to pull the trigger and make the trade. Once you have made the buy write it down in your trading plan to study later after you have excited the trade. Now that the trade is in place you need to look at where you want to hit the sell button. As a profitable trader you do not want to get greedy. Take a look at where you see resistance check your level II to see where the sellers are stacking up. If the trade is moving in a positive direction it is time to set up a trailing stop.
