Swing trading is one of the most popular forms of active trading, where traders look for intermediate-term opportunities using various forms of technical analysis. If you're interested in swing trading, you should be intimately familiar with technical analysis. Investopedia's Technical Analysis Course provides a comprehensive overview of the subject with over five hours of on-demand video, exercises, and interactive content cover both basic and advanced techniques.

Based on particular setups, any trading system can be used for the purposes of scalping. In this regard, scalping can be seen as a kind of risk management method. Basically, any trade can be turned into a scalp by taking a profit near the 1:1 risk/reward ratio. This means that the size of the profit taken equals the size of a stop dictated by the setup. If, for instance, a trader enters his or her position for a scalp trade at $20 with an initial stop at $19.90, the risk is 10 cents. This means a 1:1 risk/reward ratio will be reached at $20.10.
The basic strategy of news playing is to buy a stock which has just announced good news, or short sell on bad news. Such events provide enormous volatility in a stock and therefore the greatest chance for quick profits (or losses). Determining whether news is "good" or "bad" must be determined by the price action of the stock, because the market reaction may not match the tone of the news itself. This is because rumors or estimates of the event (like those issued by market and industry analysts) will already have been circulated before the official release, causing prices to move in anticipation. The price movement caused by the official news will therefore be determined by how good the news is relative to the market's expectations, not how good it is in absolute terms.

Many swing traders assess trades on a risk/reward basis. By analyzing the chart of an asset they determine where they will enter, where they will place a stop loss, and then anticipate where they can get out with a profit. If they are risking $1 per share on a setup that could reasonably produce a $3 gain, that is a favorable risk/reward. On the other hand, risking $1 to make $1 or only make $0.75 isn't as favorable.
This combination of factors has made day trading in stocks and stock derivatives (such as ETFs) possible. The low commission rates allow an individual or small firm to make a large number of trades during a single day. The liquidity and small spreads provided by ECNs allow an individual to make near-instantaneous trades and to get favorable pricing.
Another trading method is known as fading the gap at the open. When the opening price shows a gap from the previous day’s close, taking a position in the opposite direction of the gap is known as fading the gap. For days when there is no news or there are no gaps, early in the morning, day traders will take a view on the general direction of the market. If they expect the market to move up, they would buy securities that exhibit strength when their prices dip.

Once you have a specific set of entry rules, scan through more charts to see if those conditions are generated each day (assuming you want to day trade every day) and more often than not produce a price move in the anticipated direction. If so, you have a potential entry point for a strategy. You'll then need to assess how to exit, or sell, those trades.
