IsValidDataPointAt()

Previous page Return to chapter overview Next page

Definition

Indicates if the specified input is set at a specified bar index value.  Please also see the Reset() method for more information.

 

Notes:

If called directly from the instance of the NinjaScript object, the value returned corresponds to the Inputs Series (e.g., Close, High, Low, SMA, etc.)
When checking a Bar or PriceSeries, IsValidDataPoint() returns true as long as the barIndex value falls between 0 and the total count for that series.  These are special series which always contain a value set at every slot index for multi-series scripting purposes (e.g., comparing two price series with various session templates, or one series has more ticks than the other)
For a Value series or custom Series<T>, IsValidPlot() returns true or false depending on if you have set a value at that index location

 

 

Method Return Value

A bool value, when true indicates that specified data point is set; otherwise false.

 

Warning:  Calling IsValidDataPointAt() will only work a MaximumBarsLookBackInfinite series.  Attempting to check IsValidDataPointAt() MaximumBarsLookBack256 series throw an error.  Please check the Log tab of the Control Center
