Line on current price

[JoshDance]

Sorry for such an elementary question, but I am trying to plot a line that shows the last traded price, that goes from the last bar and rightward towards the price display itself, as show in the attached picture. What method would I use to accomplish this? Thanks for any help you can provide.

Obviously, this line should update with each price change.

Hello JoshDance,
Thanks for writing in and I am happy to assist you.

You can simply draw a ray to accomplish this.

if (CurrentBar > 1) DrawRay("ray", 1, Close[0], 0, Close[0], Color.Blue);

Joydeep, thank you for your help. As you can see, this draws the ray through the last two bars.. is there a way to make the ray only draw from the very last bar to the right?

Hello JoshDance,
Please use this modified code

DrawRay("ray", 0, Close[0], -1, Close[0], Color.Blue);

Hello JoshDance,
Thanks for your note.

Actually Joydeep, after using this for a few minutes, I notice an issue. With the second piece of code, when I zoom all the way out (I suppose what I really mean is that I reduce the bar spacing as far down as possible), I get the first picture here, where the ray appears vertical. At any other higher bar spacing, it works fine.

How can I check the bar spacing? If I determine it's zero (or whatever the minimum is), then I can use the first piece of code. Else, I'll use the second piece.

Also, given that I have no plots here, how can I allow user input of a color so I can let the user change the color of the ray? I'd prefer not to have three ints for RGB values if possible, I'd like an actual color.

Hello JoshDance,
Unfortunately there are no supported method for finding the bar space. However you may look into the unsupported ChartControl class regarding this.

Please let me know if I can assist you any further.

[JoshDance]

I used ChartControl, thank you. How about accepting the input color as I asked in the prior post?

[NinjaTrader_Joydeep]

Hello JoshDance.
Yes, you can use Color inputs as a select-able parameter. Please refer to this post which demonstrates it.
