Public ReadOnly Property Point1 As FinancialIndicatorPoint

Property Value

Type	Description
FinancialIndicatorPoint	A FinancialIndicatorPoint object, which represents the financial indicator’s first point.

Remarks

To create a FinancialIndicator class descendant (FibonacciIndicator or TrendLine), it is necessary to specify its Point1 and FinancialIndicator.Point2 properties.

And, each point requires its FinancialIndicatorPoint.Argument and FinancialIndicatorPoint.ValueLevel properties to be specified, which are used to obtain a point’s argument and value from the series data, for which the current financial indicator is drawn.

For more information, see Indicators.

Example

This example demonstrates how a Trend Line can be added to a series’ collection of indicators at runtime.
