SMA vs. EMA

Which is better: Simple or Exponential?
First, let’s start with an exponential moving average. When you want a moving average that will respond to the price action rather quickly, then a short period EMA is the best way to go. These can help you catch trends very early, which will result in higher profit. In fact, the earlier you catch a trend, the longer you can ride it and rake in those profits!
The downside to the choppy moving average is that you might get faked out. Because the moving average responds so quickly to the price, you might think a trend is forming when in actuality; it could just be a price spike.

With a simple moving average, the opposite is true. When you want a moving average that is smoother and slower to respond to price action, then a longer period SMA is the best way to go.

Although it is slow to respond to the price action, it will save you from many fake outs. The downside is that it might delay you too long, and you might miss out on a good trade.

SMA :

Pros:
Displays a smooth chart, which eliminates most fakeouts.
Cons:
Slow moving, which may cause a lag in buying and selling signals.

EMA :

Pros:
Quick moving, and is good at showing recent price swings.
Cons:
More prone to cause fakeouts and give errant signals.

So which one is better? It’s really up to you to decide. Many traders plot several different moving averages to give them both sides of the story. They might use a longer period simple moving average to find out what the overall trend is, and then use a shorter period exponential moving average to find a good time to enter a trade.

In fact, many trading systems are built around what is called “Moving Average Crossovers”. Later in this course, we will give you an example of how you can use moving averages as part of your trading system.
