BNPoint Class
The BNPoint class is used to define a drawing object point based on a bar number and a price value. Drawing objects positioned with a BNPoint will move along with the bars they are anchored to when the chart is scrolled.
A BNPoint refers to the absolute bar index (zero-based) of the collection of bars in a chart. Note that this is not the same as the CurrentBar reserved word which counts the number of bars available for analysis after MaxBarsBack. This means that if you want to plot a drawing object (such as a VerticalLine) on the 4th plotted bar in a chart, you would specify a BNPoint index of 3.
For example, if MaxBarsBack is 10 and your analysis technique is calculating at current bar 20, the following code snippet will plot a VerticalLine drawing object on the bar with a BNPoint index of 20 from the start of the chart, which is the same as the CurrentBar.
If CurrentBar=20 then Begin
myBNVertLine = VerticalLine.Create(BNPoint.Create(CurrentBar+MaxBarsBack-1,0));
DrawingObjects.Add(myBNVertLine);
End;
