Indicator Settings
An Indicator is a visual technical analysis tool, used to analyze market conditions and identify and forecast trends and market patterns. An indicator is a visualization of a mathematical formula, and consists of one or more Plots – lines, histograms, series of points or crosses, highs and lows, left and right ticks, or a combination of the above. Indicators are computed using the price, volume, and (occasionally) open interest data.
Using Indicators
Each indicator, applied to a chart, is set individually and has its own Format Indicator window. Indicator Title is displayed in the title bar of the Format Indicator window. Multiple instances of the same indicator can be applied to the same chart; each instance will have its own Format Indicator window, allowing different settings to be used for each of the instances.
Basic adjustments to the indicator's logic can be made by changing the Input Values. Indicator Style, Maximum Bars Back value, and Base Data Series can be set, and the recalculation frequency selected.
Setting Input Values
An Input is a constant used in the indicator calculations. Indicators can have one or more inputs, or none at all.
Each input is assigned a name. There are three types of inputs: Numeric, True/False, and String.
Indicators can be modified by changing the input Values.
One of the main advantages of using the inputs is that basic adjustments to the study's logic can be made by simply changing the input values, without the need to edit the studies' actual code.
Most, but not all, indicators use input values; to learn more see Default Studies Inputs. The inputs can be modified before as well as after the indicator has been inserted.
Indicator Inputs can be set from the Format Indicator window:
- Open the Format Indicator window.To open the Format Indicator window, position the mouse pointer over the indicator; double-click once the Pointer
changes into a Hand
.
The Format Indicator window can also be opened by one of the following methods:
- Position the mouse pointer over an indicator; once the Pointerchanges into a Hand
, right-click and then click Format Indicator Name
- Open the Format Objects window; in the Indicators tab, select an indicator and click the Format button. See Opening Format Objects Window.
Note: The Format Indicator window for the indicator being inserted will open automatically if the Format check box in the Insert Study window is checked. - Select the Inputs tab.
- In the Value column, click on the value of the input that you want to change and enter the desired value.
Setting Style
The Type, Color, Style, and Weight of the indicator's plot can be customized; if an indicator consists of multiple plots, each plot can be set individually.
Changes to indicator style settings will be applied to the Chart Window in real time.
Indicator style can be set from the Format Indicator window:
- Open the Format Indicator window.To open the Format Indicator window, position the mouse pointer over the indicator; double-click once the Pointer
changes into a Hand
.
The Format Indicator window can also be opened by one of the following methods:

- In the Style column select the plot style from the drop-down list box.
- In the Weight column select the plot weight from the drop-down list box; the weight can only be selected for the solid line style.
Setting Maximum Bars Back
All indicators based on past data use a certain number of bars for their calculations. The number of bars is called Maximum number of bars a study will reference, or Maximum Bars Back. You can select to set this value manually, or to have it set automatically (Auto-Detect). The Maximum Bars Back value cannot be smaller than 1 and cannot be greater than actual number of bars on the chart. This value shows how many bars a study requires to be calculated before it can plot first results on the chart. It means that there can be no plot or any other visual output on the X number of bars at the beginning of the chart, where X = MaxBarsBack or Maximum number of bars a study will reference.
Auto-Detect Maximum Bars Back
Automatic detection of the Maximum Bars Back value can be chosen from the Format Indicator window:
- Open the Format Indicator window.To open the Format Indicator window, position the mouse pointer over the indicator; double-click once the Pointer
changes into a Hand
.

Setting Last Price Marker
Last Price Marker is a special label displayed on the price scale that indicates the latest value of indicators' plots.
If an indicator (study) has multiple plots then the markers can be displayed for each plot.
The color of each marker is the same as of the corresponding plot.
To turn on/off Last Price Marker for an indicator (study):
- Open the Format Indicator window.To open the Format Indicator window, position the mouse pointer over the indicator; double-click once the Pointer
changes into a Hand
.
The Format Indicator window can also be opened by one of the following methods:
- Position the mouse pointer over an indicator; once the Pointerchanges into a Hand
, right-click and then click Format Indicator Name
- Open the Format Objects window; in the Indicators tab, select an indicator and click the Format button. See Opening Format Objects Window.
Note: The Format Indicator window for the indicator being inserted will open automatically if the Format check box in the Insert Study window is checked. - Select the Style tab.
- In the Marker column, select or deselect the checkboxes for the corresponding plots.
The Last Price Marker can also be used to control how a study is displayed in the Scanner.
For example, the RSI study contains three plots, each with its own marker checkbox.
To display the data for only one of the three plots in the Scanner:
- Uncheck the other two markers.
- Check Use as default.
- Click OK.
The next time this study is added to the Scanner, only the plot that was checked will be displayed in the Scanner.
