Swing trading is a specific style of trading. It is neither day trading nor trend following and falls somewhere in between. What we are aiming for is to capture short duration trades, normally a few days to a week or so, when the markets we monitor show specific set-ups. The edge to successful trading is finding an imbalance between buyers and sellers. As markets are largely random in nature, most of the time no such edge exits, however when an imbalance occurs we can align ourselves in the direction that we believe the market will take. This edge may exist for a short time only and is never a guarantee of success. 
By only taking the best set-ups and quickly dispatching losing trades, it is possible to become profitable over a large number of trades. No one trade should ever take us out of the game and shooting for singles is the aim. Once in a while we will catch a home run, but the object is to take slow and steady profits from the markets.
We find from monitoring trade results that broadly speaking 40% of trades are winners, 30% lose and 30% are break-even. The winning trades are around twice as large as the losing ones, thanks largely to stops being tightened aggressively. As with all successful trading, position sizing and risk management are key components towards a profitable outcome!
