Chart Indicator Parameters

The following parameters are common to all indicators applied on a chart:

 

Indicators2

 

Input Series

Please see the "Indicator Input Series" section on this page for further information.

Calculate

Sets the frequency at which the indicator performs its calculations. See the note below for information on each possible setting for this property

Label

The label displayed on the chart. Leaving the field blank will remove the label from being displayed on the chart. Enclosing a label in quotations ("MyEMA" for example) will display the text within the quotations and exclude the system added trailing series information.

Maximum Bars Look Back

Determines the maximum number of bars the indicator can look back to perform calculations on historical data. This is set to 256 by default (the most memory-friendly setting), but it can be changed to "infinite" to allow for a greater look back period.

Auto Scale

When enabled, the indicator will be included in the chart panel's vertical automatic scaling

Displacement

Sets the number of bars by which to displace the indicator plots

Display in Data Box

Enables or disables the inclusion of the indicator's plot values in the Data Box

Panel

Sets the panel in which the indicator is plotted. If you select "Same as input series," the indicator will be linked to the Input Series and automatically move if the Input Series is modified to a different panel.

Price marker(s)

When enabled, the indicator value is plotted in the axis selected under the "Scale Justification" property.

Scale justification

Sets the scale axis on which the indicator will be plotted within its selected panel. See the Navigating a chart page for additional information.

Visible

Enables or disables visibility of the indicator on the chart

Plots

Sets a variety of parameters, such as color, for the plots drawn by the indicator

 

Note: The "Calculate" property offers three possible settings to control how often an indicator performs its calculations:

On Bar Close - Run calculations once on the close of each bar of the Input Series
On Each Tick - Run calculations on each incoming tick of price data (CPU intensive)
On Price Change - Run calculations at the close of a bar if that bar's Close price differs from its Open price

 

Saving an Indicator's Parameters as Default

You can optionally save your customized indicator's parameters as default. Doing so will recall your customized settings the next time you add that specific indicator to a chart.

 

Please see the Saving Chart Defaults and Templates page for more information.

 

Indicator Input Series

The indicator Input Series dialogue allows you to select the Input Series for your indicator's calculations. To access this window, left mouse click within the "Input Series" field. You can then select the Close, High, Low, Median, Open, Typical, or Weighted price of any Data Series applied to the chart. Alternatively, you can choose another indicator as the input series. When you select another indicator as the input series, The "Properties" section of the Input Series dialogue will display properties related to the indicator being used as the Input Series, allowing you to configure it to your desired settings. This allows you to nest multiple indicators. Once you have selected the Input Series of your choice, left mouse click the OK button to exit the Input Series window.

 

Indicators4

 

In the image above, we can select one of the Data Series applied to the chart, or another indicator, for use as an indicator's Input Series.

 

Note: To take advantage of this feature NinjaScript indicators will need to implement the Input ISeries as their main data input.

tog_minus        How to remove an indicator

Removing an Indicator From a Chart

There are three ways to remove an indicator from a NinjaTrader chart:

 

Open the Indicators window (see the "Understanding the Indicators window" section above). Next, select an indicator from the "Configured" section, then select the Remove option, and finally press the OK button to exit the Indicators window.
Left mouse click to select the indicator on your chart, then press the Delete key on your keyboard.
Left mouse click to select the indicator on your chart, then right mouse click the indicator and select the Remove menu item.

tog_minus        Custom indicator development

In addition to the indicators that come pre-built with the NinjaTrader application, you also have the ability to create custom indicators of your own. For example, you could create your own custom multi-series indicators using price and volume data to apply to your charts or share with fellow traders.
