Trying to draw text for all historical occurrences

[mntemel]

Hi, I used EasyLanguage in the past and decided to switch to Ninjascript, I'm quite new to it.

I think i'm still not clear on how variables work. To keep it simple I'll ask this question, which might help me with the more complex question I have.

So I want to draw text, an "H" when ZigZag indicator makes a high

this code gives me how many bars ago a High occurred in ZigZag indi

int first_high_barsAgo = ZigZag(DeviationType.Points, 0.0002, true).HighBar(0, 1, 999);

So now I know the position of the High. Here below I'm drawing a text at the High.

if  (first_high_barsAgo > -1) 
{
Draw.Text(this, @"v3 Text_1", @"H", first_high_barsAgo, High[first_high_barsAgo]);				
}

This is all good and works, but when I add this strategy on a chart, the Text "H" keeps moving when a new high occurs. How do I see all historical drawings, and when a new high occurs the text stays in place and an additional new text is written on the new occurrence? I tried turning first_high_barsAgo into a variable and also created a new variable for the High's as well but didn't work. If you could help please...

Thanks

Hello mntemel,

Thanks for your post and welcome to the NinjaTrader forums!

Draw objects on the chart must have unique tag names. If you use the same tag name then when a new one is drawn, the previous one is removed.

To create a unique tag name a common approach is to add the current bar number. For example:

Draw.Text(this, @"v3 Text_1"+CurrentBar, @"H", first_high_barsAgo, High[first_high_barsAgo]);
