Indicator Builder

Indicator builder window enables you to define your own custom indicators. Indicators are definable using formulas written in AmiBroker's own formula language. You can find the description of this language in AmiBroker Formula Language Reference Guide.

You can define up to 2000 custom indicators which are listed on the left side of the window.

In upper right part of the window you can see the text field where you should enter the formula of an indicator.

In the bottom right part of the window you can define scaling options for the chart and the way the grid is drawn.

• Add button adds a new (empty) indicator to the list
• Delete button deletes currently selected indicator
• Rename button allows you to rename currently selected indicator
• Apply button causes AmiBroker to reinterpret the indicator formula and display updated chart.
• Load/Save formula buttons allow to load/store the formula of current indicator to the external AFL file
• Close button closes the indicator builder window.

By default up to 3 different graphs can be plotted within one indicator window. The formulas defining these graphs should be assigned to reserved variables named: graph0, graph1, graph2. You can change however maximum number of graphs by assigning different number to a maxgraph variable.

For example:

graph0 = macd();
graph1 = signal();
graph2 = macd() - signal();

First two graphs (graph0 and graph1) are plotted using line chart. The last one (graph2) is plotted using histogram chart.
