Get Draw Line Style, Width & Color From User Inputs

[MercuryScripter]

Hello,

My strategy is designed to add horizontal lines to the chart. I would like to assign the Style, Color and Width properties based on user specified values.

Would appreciate syntax required to access those properties. Thank you!

To specify, I am wondering if there is a easy, consolidated way to acquire these values or do I have to capture them individually by type?

Hello,

The Width property would be the simplest one to do this way, since it requires an int. You could simply expose a public int property that the user could enter.

The Color and Style properties will be a bit different, because these items are enumerated constants (enums). The way I've seen others accomplish this is to peg the enums to integers, then add a sort of key to which number represents which selection in the description of the property. This way, when a user clicks within this property's field when setting up the indicator or strategy, they will see a description that says "1 - Blue, 2 - Red, 3 - Green," etc.

Then, you can use a switch statement on the exposed property before drawing the line. This would not be the most elegant code design, but it would get the job done. Something like the following:

switch userColor
{
case 1: DrawHorizontalLine(x,x,x,Color.Blue,x,x);
break;
case 2: DrawHorizontalLine(x,x,x,Color.Red,x,x);
break;
}

You could do this for both the Color and Style. The links below will show you all of the possible values for these enums:

And just in case, here is the link for the proper syntax for DrawHorizontalLine().

Please let me know if I can assist further.

Hello Dave, thank you again for your response. I have a follow up question. Most indicators have a "Plots" section that enables the user to assign the plot properties. How can I use that property to enable the user to set the properties of the horizontal lines I wish to add to my charts through my strategy? Thank you!

Hello,

I've worked up a sample script that will show how the setup I proposed would work (see attached). In this sample, there are exposed integer properties for the line width, color, and dash style, then "switch" and "if" statements are used to draw the line based upon the user's input.

Also, the information that Michael mentioned in the post below will apply, as well:
