Indicator with DrawTextFixed Output

[laocoon]

Hello

I've developed an indicator that draws text on the price chart when certain criteria are met. Here's the code:

DrawTextFixed("tag1", "Long", TextPosition.TopRight, Color.Green, Font.Arial, Color.Black, Color.Black,2);

I'm getting the following error message when compiling:
System.Drawing.Font does not contain a definition for ''Arial''.

I'd very much appreciate if someone could help me out here.

Thanks

Hello laocoon,

The line below should work for you:

 
DrawTextFixed("tag1", "Long", TextPosition.TopRight, Color.Green, new Font("Arial", 12), Color.Black, Color.Black,2);

perfect, thanks a lot Ryan!

Hello RyanM,

I'm using the DrawTextFixed command as you suggested and it works great, I have a problem however to remove the text at a later stage (ie if the entry signal is no longer valid).

Here's what I did:

DrawTextFixed("tag1", "X", TextPosition.Center, Color.Black, new Font("Arial", 30), Color.Black, Color.White,2);

if (High[0] > High[1] || High[0] < High[1])
{
RemoveDrawObject("tag1" + (CurrentBar -1));
}

This doesn't work as planned, the text stays on the chart.
I'm guessing that it has something to do with the fact that DrawTextFixed is not compatible with RemoveDrawObject, but I'm not sure how to code it differently.

Thanks

The issue is likely the tag you attempt to using for the remove call, it would not align with the one you assign upon creating the drawing object.

[laocoon]

Thanks for your reply Bertrand.
What do you mean by "the tag would not align"? I don't understand this as both tags are identical.

Thanks

[NinjaTrader_Bertrand]

No, they would not be, for the later one you add the CurrentBar string, while for the former not.

[laocoon]

Ah OK, I thought the tag was only the text that's between "..." quotation marks.
The CurrentBar string is necessary, because otherwise the text is not drawn on the chart, or is there a better way to do it?

Thanks

DrawTextFixed("tag1", "X", TextPosition.Center, Color.Black, new Font("Arial", 30), Color.Black, Color.White,2);

if (High[0] > High[1] || High[0] < High[1])
{
RemoveDrawObject("tag1" + (CurrentBar -1));

You're using 2 different names, hence you attempt to remove an object with a tag that's never been used. You would remove the object with the tag1 name.

[laocoon]

I understand what you're saying, but if I modify the code like this (to create identical tags):

RemoveDrawObject("tag1");

the object is not even drawn on the chart in the first place.

Probably because it's removed everytime when you're trying to draw it?

Please see the condition you use to remove it, that would be true for a high percentile of bars you would see.

I understand what you're saying Bertrand. I was just trying to remove the tag once the current bar is closed (which in my setup invalidates the signal and thus makes the tag useless).
I'm sure there is a better way of achieving this but I didn't find it yet.

This is your original code.

if (High[0] > High[1] || High[0] < High[1])
            {
                RemoveDrawObject("tag1" + (CurrentBar -1));
            }

The only time your filter condition is not true (and hence the object removal code does not run) is if, and only if, High[0] is equal to High[1], a pretty low occurrence at pretty much anytime. IOW, your removal code is almost certain to be run on every bar.

[laocoon]

Thanks for your comment Koganam, you're absolutely correct.
This was actually intended, as the " High[0] is equal to High[1]" condition is the only condition in my strategy where the tag can REMAIN on the chart (after the bar has closed and the new one opens).

I'm still looking for an easier way to code this though, as the thing I'm really trying to achieve is the following:

If strategy conditions are met (on 10 min chart): draw tag on chart
Once current 10 min bar has closed (and thus signal is no longer valid): remove tag
If conditions are met again on another 10 min bar: draw tag
etc.

It sounds embarassingly easy but I wasn't able to code it so far.

Thanks

Hi laocoon,

For this implementation you may not need to add + CurrentBar to provide a unique tag, as you're only drawing one thing at a time. I would suspect you could create this with something like:

if(Close[0] > Open[0])
DrawTextFixed("myTag", "myText", TextPosition.BottomLeft);
		
else RemoveDrawObject("myTag");
