Can I use DrawRectangle/DrawRegion in the indicator panel?

[kaywai]

If so how do I do that?

The other question I have if I can achieve the first issue is, how do I get the region to "extend" as long as the condition is true?

Yes Kai, provided you set DrawOnPricePanel to false - http://www.ninjatrader.com/support/h...pricepanel.htm

You would run a counter for each bar that the condition is true and then extend your drawn region / rectangle - http://www.ninjatrader.com/support/f...ead.php?t=3419

Hi Bertrand, Thx for showing me how to draw on the indicator panel.

I am unable to "extend" the DrawRectangle. Here is my code:

Would you mind helping?

Looks good to me Kai, though you could problably work in some loops making the code cleaner...

[kaywai]

I don't like the lines inside the rectangle and I would prefer a uniform fill which I am not getting because I'm using "CurrentBar" to draw the rectangle...just looking for ways to improve the aesthetics.

Appreciate it if you could help.

What is your code line for the rectangles?

[koganam]

Here you go Koganam!

I'm trying to achieve something similar to the attached image minus the line inbetween and the way the fill is displayed...is there an alternative to using CurrentBar?

See if this cuts it.

			if (result1 >= 60)
			{
				******erisoverbought = true;
				if (******erisoverbought == true)
				{
					overboughtcounter++;
					if (overboughtcounter == 13)
					{
						OBRect = CurrentBar;
						OBRectTag = "OBPOQ" + CurrentBar.ToString();
					}
					if ((overboughtcounter > 13))
					{
						DrawRectangle(OBRectTag, true, CurrentBar-OBRect, 60, 0, 100, Color.Transparent, Color.Magenta, 1);
					}
					else return;
				}
			...

Notice that because part of your variable name (the Tom DeM... part) is copyrighted, the NT forum has substituted asterisks for that part of the string.

[kaywai]

I understand totally Koganam! Thx much! Will try it out tonight!

NT,

I tried using drawRegion in OnMarketDepth this week and NT just logs an error and the indicator locks up.

Error - endBarsAgo out of valid range 0 through -1 was 0.

OnMarketData and OnBarUpdate are working fine with DrawRegion..

Hi Koganam,

The lines in the rectangle was faint but the color fill is darker on the left part of rectangle.

BTW I had to set up a OBRectTag variable...not sure how to do that! Lol!

Why do I not simply rewrite the file?

There are 3 additions: 1 in the variables section, 2 in the OnBarUpdate() method.
There are 2 changes, both in the OnBarUpdate() method.

The additions are clearly remarked in the file.

The file is attached. Just save your existing file to another name (if you really want to retain it), and copy this one over into the same folder as the original.

Hi Koganam,

U da Man! Thx dude!

Using DrawRegion in Indicator Panel

Just a quick comment on the use of DrawRegion() in the Indicator panel when using the Default Initialize setting DrawOnPricePanel = true. You may "sandwich" in OnBarUpdate() a DrawRegion() function in between DrawOnPricePanel = false and DrawOnPricePanel = true and NT will draw all other objects in the Price panel but will fill the DrawRegion in the indicator panel.
