horizontal line indicator

[nightriderx]

Hi,
I am developing an indicator that needs to have a number (about 10) of horizontal lines redrawn every time a calculation is done, however only the last line I draw seems to show up. Can you point me to an example that would do something like this (i think I saw a Fibinochi indicator once that worked like this but cant seem to find it)
thx!

Hello nightriderx,

You need to have an unique tag for each line.

Example with three horizontal lines:
DrawHorizontalLine("tag1", 1001, Color.Black);
DrawHorizontalLine("tag2", 1002, Color.Black);
DrawHorizontalLine("tag3", 1003, Color.Black);

so if these lines are generated in a loop - how could I do that? (other than breaking up the name "tag1" to "tag" + converting the loop counter to text, etc...? -would really try to stay away from doing this)

[nightriderx]

also, I would like to get the values of the lines to display in the data box. I have the "display in databox = true in the initialize field but the data box still does not display the values... do I actually need to turn the values into a data set or is there a way just to display the plotted lines?

thx!

You may consider appending the loop counter variable to the tag. I'm not aware of a different way to make them unique within a loop. Maybe our members with C# experience know of another way.

for (int x = 0; x < 9; x++)
{
DrawHorizontalLine("tag1" + x, 1000, Color.Black);
}

The data box displays plot values only, so to view these lines in a data box would need to convert to plots.

o wow, that +1 actually worked. thats fine. I assumed that I had to break up the text and convert it. but this is good.

as for getting the values in the data box - im plotting the lines using a "DrawLine" command in the on bar update section with a "add(new plot..." in the initialized section.... everything plotting but not showing up in the databox

thx again!

Great that it works for you.

DrawLine() won't produce values you can see in a data box. Data box is plots only, like:

Plot0.Set(myLineValue);

[nightriderx]

ok so the "draw" command works in a loop but does not display values in the data box...
The plot command displays in the data box but how would you suggest getting the new plot name (ie. Plot0.Set, Plot1.Set) in a loop?

[NinjaTrader_RyanM1]

Unfortunately not aware of a way to set plots in a loop. There may be a creative programming solution available here, but it's beyond our scope of support. Would be neat to see if our community members can come up with something.

Copy-pasting the .Set commands and making small changes to each line is likely the easiest way to go.

If you just need a visualization of the line values you can use the same loop and add the text in the right margin with DrawText().

ok, the other thing that I am trying to do is pass an array from an indicator to a strategy...is this supported in nt? if so can you please point me in the right direction? The array seems to work fine in the indicator but cant seem to access it in the strategy, all im getting is 0's
thx

nevermind, found a way to do it
