Remarks

Call this method to display a financial marker (a FinancialMarker object is appended at the end of the financial markers collection). Note that the Insert method can also be used (the order in which these objects are stored only determines the order in which they are drawn).

A financial marker graphically compares two prices, which are represented by two data points in a series.

The marker that is displayed is determined by the markerType parameter.
