But rate of return and win rate are important. Taking a 50% profit instead of riding to 100 could make you unprofitable

Or you could take that 50% return selling 1/3 of your position. Update stop to break even and let it ride another 1 or 2 R's and take another 1/3 off updating stop as it goes higher to stop out last 1/3. Hell I even add to my position when I see fit I'd I get into a good winner. 
  
 But locking in that first 1/3 profit or any bit of profit is very valuable in being able to control your trade/emotions
