The MACD Explained in Forex Trading
The MACD (Moving Average Convergence Divergence) is also a popular technical
trading indicator that is used by traders the world over. It was invented by a trader called George Appel in
the late 1970’s, and can be used as either as a trend or momentum indicator.
The MACD calculates the differences between the closing prices of an instruments 12 and 26 period exponential
moving averages. The 12 period ema is the faster; and the 26 period ema the slower.
A 9 period exponential moving average of the MACD itself is also plotted and represented as a histogram in the
indicator window and also serves as our trigger to enter or exit the market.
The MACD signals a buy signal when it crosses above it own 9 period exponential moving average; and a sell
signal when it crosses below its 9 period EMA. The histogram is positive when it crosses above its nine period ema
and negative when it crosses below it 9 period ema.
When price is rising the histogram bars grow longer as price momentum increases accelerates and they contract
when momentum slows. The same principal works in reverse as price drops.
The MACD is also a useful tool for identifying divergence which occurs when price is going in one direction but
the indicator is going in the opposite direction.
Trading with the MACD
We enter a trade long when the histogram bar crosses above its 9 period moving average: short when the histogram
bar crosses below its 9 period moving average as can be seen on the following chart.
On this chart we can identify a number of trades where the green shaded areas represent the buy opportunities
and the gold shaded area the sell opportunities. When the histogram bars open above the zero line this is a good
indication that the market is confirming or entering a new uptrend. When the histogram opens below the zero line
this is often a good indication that the market is entering a new bearish trend.
As we can see from the MACD Chart Tutorial 1 but one, of the trades were good with two very profitable trades. We
can also see that two of the short trades were preceded by bearish divergence where we could have used the
divergence to enter the market sooner than waiting for the cross. The one bullish divergence failed and resulted
in a loss, but in fairness occurred during a very quiet period in the market when we probably would not have
made a trading decision.
The 12, 26, 9 MACD settings used on this chart are the standard settings for the MACD; but like most indicators
the sensitivity of the indicator can be changed to suit different time frames and instruments.
If we look at the second MACD Chart Tutorial 2 all but one of you can see I have changed the settings to 10, 22,
and 5. Most of the trades had better entry points than with the standard settings. The more sensitive settings
can lead to more false signals though. So it is always a toss up between earlier entries and fake outs.
As there are very few “one size fits all” indicators we need to test various settings on the different time
frames until we find one that offers a good balance between entry and false signals for our preferred time frame
and currency.
