Draw Horizontal line programmatically

[yameen.forex]

Hi,

I would like to write an indicator which should draw a horizontal line (like ConstantLine indicator comes default with NT). But, we need to provide values to this ConstantLine indicator and has a limitation of accepting only 4 values.

However, I would like to draw the horizontal lines on every Pshycological number (.00, 0.25, 0.50, 0.75). I tried to search the similar kind of indicator or the programming idea in this thread but with no success.

Can someone tell me how to add new Plot dynamically using C# code? Your help would be very much appreciated.

Thanks

yameen.forex, the ConstantLine indicator would work via Plots and those could unfortunately not by dynamically added in - what you can look into is creating your study via regular lines dranw via DrawLine calls - http://www.ninjatrader.com/support/h...7/drawline.htm

Hi Bertrand,

Thanks for your reply. I have seen the DrawLine() method in the documentation, but I need to display the constant lines regardless of these parameters (startBarsgo, StartY, etc..). I have been using this custom indicator on MetaTrader4 Platform, attached screenshot for reference.

Any more ideas would be very much appreciated.

yameen.forex, thanks - if you do not wish to work with the DrawLine signatures to create those on the fly, you could alternatively look into complete custom plotting via an overriden Plot method as well - this would be then done purely via C# and unfortunately not much documented / supported by us. The CustomPlotExample and Pivots indicators installed per default with NT though could be used as starting point.

For this type of study, I would just go with an amended Constant Lines indicator that would contain a higher # of plots. Since most the lines would not be viewed anyways in realtime going forward wih this study.

Use a for loop in OnStartUp() to draw the lines if you want static lines. Use OnBarUpdate() if you want dynamic lines.
