It doesn't always work the first time
Many times you may be right but have incorrect timing or stop out area. As long as a trade is holding strong and not going against you past your planned stop loss it's best to wait and let it play out. To many times trades will scare you out only to run your way after you get out.
The other method is to take small profits when possible, add along the way, stop out quickly but reenter if warranted and keep trying if the stock seems likes it wants to go and is holding support. You never know when the market makers or computer orders will kick-in and the stock will take off, as seen below.
