Annotating The OBV And $NYAD Cumulative Charts

 | 

I recently received an email asking why some of the annotations didn't track properly.

Here is a chart of a cumulative chart type with annotations.

I want to point out a few things. Because the chart is calculated as "cumulative" the annotations do not track. You will notice the 2 red lines are not in line with the price action they are overlaying. This is normal on a cumulative chart. The other thing to notice is when you use the angle line tool, the lines will only remain at the length you originally drew them. They will not continue to extend to the right as the chart updates. A horizontal line which is the 3rd box from the left on the annotation tool will continually update and get extended as new days come on the chart.$NYAD 20140211

Because it is a cumulative chart, all the annotations are moved including your text boxes. So as the left edge changes on the chart, my annotations circled in red have pushed down. The line marked B is a horizontal line made with the angle line tool so it does not extend to the right. The line marked A does.

To get the extra white space on the right of the chart, use the 'extra bars' in the Chart Attribute area.

You will have the same appearance with an OBV chart.

If you have other questions on annotating, feel free to ask me or use the help box on the top right of the annotate box. It is actaully a help box that helps.

Good trading,
