BlockVolume

[Sinks]

I'm having a little trouble with my first attempt changing the BlockVolume indicator a little. The indicator will plot a bar in the sub-panel and I want to plot a Ray on the the chart. I want to use a ray so that in the future I can attach info to the line and show the start. The trouble I have now is I have changed the IsOverlay to true and I changed the PlotStyle to Line. Now I have a error CS0101 saying the "global namespace allready contains a definition for CountType" on line 116. I have not made any changes to the OnBarUpdate yet.......I know I need to do something there. I feel once I get past this hump I can start moving forward with it.

Any help would be awesome........thank you

Hello Sinks,

Thank you for your post.

The enum 'CountType' already exists in the original file. You will need to rename the enum and it's calls in order to avoid the error.

To draw on the price panel yet still plot on the indicator panel you actually need to have DrawOnPricePanel set to True and IsOverlay set to False.

Please visit the following links for more information:

• DrawOnPricePanel: https://ninjatrader.com/support/help...pricepanel.htm
• IsOverlay: https://ninjatrader.com/support/help.../isoverlay.htm

Please let me know if you have any questions.
