Can not get DrawText to work (NT6)

[RedDuke]

I created an indicator using wizard without changing anything.

The only line of code that I have in OnBarUpdate()is

DrawText("TEST", "TEST1", 5, Close[1], Color.Black);

However, nothing is being displayed on the chart. I am obviously doing something wrong.

Thanks,

Please inspect your logs. NT reports issues to the logs. It's always a good idea to check there first. There likely will be an error message

Error on calling the 'OnBarUpdate' method for indicator 'MyCustomIndicator' on bar 1: Bar index needs to be greater/equal 0

You need to code:

   if (CurrentBar >= 5)
    DrawText("TEST", "TEST1", 5, Close[1], Color.Black);

Reason: You are trying to access a bar 5 bars ago which is not yet there as the indicator processes e.g. bar 1.

We will look into making this more tolerant...

Hi Dierk,

Is there anyway to increase the size of the font?

Thanks

Not programmatically. You can change the properties of an existing text object and save them as default.

Dierk,

The logic that I have constanly removes and then draws the values. I need to remove them because otherwise the charts will be too clogged. So, even if I change the text object settings and increase the font, it obviously dissapears once it removed and drawn again. Any other way of increasing it?

Thanks,

Apart from setting and saving the default font size? Sorry no.

We just were able to figure this one out.

This line creates font object:

Font fnt = new Font (FontFamily.GenericSansSerif, 14.0F,
FontStyle.Bold);

Now, it can be used in drawing (string cnt needs to be filled with value):

DrawText("counter", cnt, 1, High[1]+2, Color.Blue, fnt,
StringAlignment.Center, Color.DarkSeaGreen, Color.DarkSeaGreen, 10);
