MACD Histogram

The signals from the MACD indicator tend to lag price movements. The MACD Histogram attempts to address this problem by plotting the distance between MACD and its signal line. Because of this, the histogram signals trend changes well in advance of the normal MACD signal, but is less reliable and should be confirmed by other indicators.

Only trade with Histogram signals when the market is trending.

The MACD Histogram can also be used to track longer cycles, using weekly or monthly data.

Trading Signals

Use Stop Losses with all trades.

Ranging Markets

Signals are stronger if

There is a bullish divergence on the Histogram; or
The signal occurs far from the zero line.

Disregard signals close to the zero line unless confirmed by a divergence.

Go long when the MACD Histogram turns up below zero.

Close the position when there is a signal to go short.

Go short when MACD Histogram turns down above zero.

Close the position when there is a signal to go long.

Trending Markets

Only trade in the direction of the trend. Signals close to the zero line are accepted provided the trend is intact.

Go long when the MACD Histogram turns up below zero.
Go short when MACD Histogram turns down above zero.

Use a trend indicator, such as a moving average, to exit from trends.

Example

Intel Corporation is shown with MACD histogram and 21-day exponential moving average. Trendlines show divergences.

Price is ranging - indicated by the flat MA. Go long [L] when the histogram turns up (far from the zero line). Place a stop below the recent Low.
Go short [S] as the histogram turns down (far from the zero line). Place a stop above the recent High.
Go long [L] - the histogram turns up and is reinforced by a bullish divergence. Place a stop below the recent Low.
Go short [S] as the histogram turns down - reinforced by a bullish divergence. Place a stop above the recent High.
Ignore the signal as it is too close to the zero line.
Go long [L] as the histogram turns up when well below zero. Place a stop below the recent Low.
A further signal to go short [S]. Place a stop above the recent High.
Go long [L] - the histogram has turned up and is reinforced by a bullish divergence. Price has broken clear of the trading range and the MA is rising - exit [X] when price closes below the MA.

Setup

The default settings are:

Slow moving average - 26 days
Fast moving average - 12 days
Signal line - 9 day moving average of the difference between fast and slow.
All moving averages are exponential.

To alter the default settings - see Edit Indicator Settings. See Indicator Panel for directions on how to set up an indicator.

Captions and trendlines: Do not use MACD if you want to draw trendlines or place captions on the histogram. These are left "hanging in the air" if you zoom or change time periods.
