Market Synopsis
The Moving Average Convergence Divergence indicator calculates 2 exponential moving averages of the lengths specified by the inputs FastLength and SlowLength. The difference between these 2 averages is then plotted as the MACD. This value is also averaged for the number of bars specified by the input MACDLength and then plotted as the MACDAvg. Finally, the difference between the MACD and the MACD average is calculated and plotted as the MACDDiff. As a trend-following indicator, the MACD may be interpreted similarly to other moving averages. When the MACD crosses above the MACD Average, it may be the beginning of an uptrend. Conversely, when the MACD crosses below the MACD Average, it may be the beginning of a downtrend. As an oscillator, the MACD can indicate overbought and oversold conditions.
Plot Information
| Number | Name | Default Color | Description |
| Plot1 | MACD | Yellow | Plots the MACD value. |
| Plot2 | MACDAvg | Cyan | Plots the MACD exponential average. |
| Plot3 | MACDDiff | Red | Plots the difference between the MACD and MACDAvg as a histogram. |
| Plot4 | ZeroLine | Dark Green | Plots a reference line at zero. |
| Plot5 | CrossBarsAgo | Default | In a grid, plots the number of bars ago that the last cross of MACDDiff over or under 0 occurred. |
When applied to a chart, this indicator displays four plots in a separate subgraph from the price data. In a grid, displays five plots.
