Lines retained on charts

[Linda1507]

Hi, I am trying to build a strategy using the builder. It places lines on the chart to correspond with signals from an indicator. As the strategy updates, previous lines are removed from the chart and new lines are drawn.

Is it possible to get the strategy to leave previous lines on the chart when the strategy updates? As I am not a programmer I need to use the builder.

Thanks

Build all the strategy in builder, on the end you have to use ninjascript editor. I recommend to use IsFirstTickOfBar. For Example
if(IsFirstTickOfBar)
{
RemoveDrawObjects();
}

The syntax will remove ALL drawn objects.

Sorry for bad english, but i just want to help

Watch out because if you use the strategy in editor, you couldn't back to builder

Hello Linda1507,

Thanks for your post.

By default when you select a draw object to draw within the strategy builder, the code is created such that only the "latest" draw object will remain on the chart. Draw objects are identified by using a "tag name". If you use the same tag name the previously drawn object is removed and replaced by the newest draw object with the same tag name. To show all of the draw objects each must have a "unique" tag name.

I've previously created a short video that covers offsetting markers and how to create unique tag names within the strategy builder, please see: https://paul-ninjatrader.tinytake.co...A4M184NTkwOTg3
