Simple moving averages (SMAs) provide support and resistance levels, as well as bullish and bearish patterns. Support and resistance levels are often useful information when determining a course of action. Bullish and bearish crossover patterns signal price points where you should enter and exit stocks.
The exponential moving average (EMA) is a variation of the SMA that places more emphasis on the latest data points. The EMA gives traders clear trend signals and entry and exit points faster than a simple moving average. The EMA crossover can be used in swing trading to time entry and exit points.
A basic EMA crossover system can be used by focusing on the nine-, 13- and 50-period EMAs. A bullish crossover occurs when the price crosses above these moving averages after being below. This signifies that a reversal may be in the cards and that an uptrend may be beginning. When the nine-period EMA crosses above the 13-period EMA, it signals a long entry. However, the 13-period EMA has to be above the 50-period EMA or cross above it.
On the other hand, a bearish crossover occurs when the price of a security falls below these EMAs. This signals a potential reversal of a trend, and it can be used to time an exit of a long position. When the nine-period EMA crosses below the 13-period EMA, it signals a short entry or an exit of a long position. However, the 13-period EMA has to be below the 50-period EMA or cross below it.
