Hi, thank you for your question!
Swing trade is a trading strategy that aims to capture short to medium-term gains in a short period of time (which usually spans from a couple of days to a few weeks). Swing trading relies mostly on technical analysis in order to register trading opportunities that match this strategy.
The goal of swing trading is to capture as much of a price rise in a given time period and capitalize on it. In order to do this, they seek primarily volatile stocks that have a wide range of movement, still, some traders may pick out more stable stocks with a shorter range of movement.
The key strategy is to identify when the price will move in the desired direction and predict how long it will move that way and sell it when it reaches its peak. Of course, this is really hard, but with experience and required knowledge, it gets easier and easier.
