DrawText

[dirtybrown]

I want to print wingding characters on my chart. I have completed the following steps as described here: http://www.ninjatrader-support2.com/...t=custom+arrow and as an example wish to print the characters as a test from OnBarUpdate using a re-created version of the Bollinger indicator


1) Added this to #region variables:
private System.Drawing.Font textFont;

2) Added to OnBarUpDate():
textFont = new Font("Wingdings",12);
DrawText("tag1","‡",period,High[period]+TickSize,Color.Black, textFont, StringAlignment.Center, Color.Transparent, Color.Transparent, 0);

But this prevents the bollinger bands from printing at all the chart is blank. Here is the entire OnBarUpDate) method:

protected override void OnBarUpdate()
{ //Set font type


Upper.Set(SMA(Period)[0] + NumStdDev * StdDev(Period)[0]);
Middle.Set(SMA(Period)[0]);
Lower.Set(SMA(Period)[0] - NumStdDev * StdDev(Period)[0]);
//DrawText("tag1", "Text to draw", 10, 1000, Color.Black);
//DrawTextFixed("tag1", "Text to draw", TextPosition.TopRight);
//DrawText("tag1", "‡", 10, 1000, Color.Black);
//IndicatorCheck();
textFont = new Font("Wingdings",12);
DrawText("tag1","‡",period,High[period]+TickSize,Color.Black, textFont, StringAlignment.Center, Color.Transparent, Color.Transparent, 0);
}

I'm doing something wrong, thanks for any advice.

If you are saying it only is broken when using wingdings, then...

I only briefly looked, but in wingdings regular chars (a-z, 0-9) represent special symbols.

So instead of sending ‡ to be drawn, instead try sending "a" or whatever corresponds to ‡.

For me when I needed this, I used Word, changed to Wingdings, and just typed out a-z, 0-9 and mapped them. I'm sure there is an easier way.

Thanks for the suggestion. I followed your suggestion and entered a , which looks to be wingding code for a down arrow. Unfortunately, it still doesn't print and also prevents the bollingers from printing on the chart.
I tried for example "9" and "," for the text with no luck.

Someone else trying to help me suggested adding this:

vFonts = new Font[4]; vFonts[0] = new Font("Arial", 10);
vFonts[1] = new Font("Arial", 15);
vFonts[2] = new Font("Arial", 22);
vFonts[3] = new Font("Arial", 32);



but I'm not sure how it relates I am new to Ninjascript

If its preventing you from printing the Bollingers I suggest you check the Control Center logs for errors.

Here is the error:

5/22/2009 11:28:11 AM Default Error on calling the 'OnBarUpdate' method for indicator 'MyCustomIndicator' on bar 0: Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index

Also note that I copied the code from the Bollinger indicator, pasted it into a new one and did a find and replace. replacing Bollinger with 'MyCustomIndicator'. Wasn't sure how else to do this or if it broke some initialization code..

Hi, you would need to debug your second DrawText statement and input the correct parameters in the overload as per this link - http://www.ninjatrader-support.com/H.../DrawText.html

This code can't work because you refer to High[period] in DrawText() and period is set to 14. To get it running you need to skip OnBarUpdate() as long as CurrentBar < period.

I am trying it with this format but not seeing the signal, I am at least getting the bollingers to show up though.

Using this statement:

DrawText("tag1", "v", 0, 5, Color.Black);

Complete code attached

dirtybrown,

As Ralph mentioned, you need to check that you have enough bars before you can do such an operation. Please see this tip: http://www.ninjatrader-support2.com/...ead.php?t=3170
