Rectangles only appear once

[arbuthnot]

Hi guys

I'm trying to get rectangles to appear on each occurrence of a condition.

However, try as I might, I've only been able to make them appear only on the latest occurrence of the condition. Although this is OK for live trading, I'd like to see these produced historically - each time the condition is met.

As an example, I've got a strategy with this code:

if (CrossAbove(EMA(14), Close, 1))
                
{DrawRectangle("My rectangle",false,10,MIN(Close,10)[0],0,MAX(Close,10)[0],Color.Green,Color.Green,3);}}

As you'll see from the below image, a rectangle is drawn only once.

Taken from NT's Help for 'DrawRectangle':

endBarsAgo
The end bar (x axis co-ordinate) where the draw object will terminate

For this parameter, I've just placed a '0', but is there a way of getting the rectangle to occur at every occurrence?

Any help with this will be much appreciated.

Hello,

You will need to use a unique tag name if you wish to have the previous drawing kept.

Try:

DrawRectangle([COLOR=#0000ff][COLOR=#0000ff]"Rectangle "+ [/COLOR]CurrentBar.ToString()[/COLOR],false,10,MIN(Close,10)[0],0,MAX(Close,10)[0],Color.Green,Color.Green,3);

For this parameter, I've just placed a '0', but is there a way of getting the rectangle to occur at every occurrence?

The above should help with resolving this as well

Please let me know if I can be of further assistance.

It works a treat!

Without your help, I would never have worked this one out.

Thanks very much, Lance!

Hi Lance - I do have another question about 'DrawRectangle'.

After you draw a rectangle using the chart drawing tools, you can then click on 'Properties' and change the width. But I can't figure out a way of doing this thru coding using DrawRectangle.

Is there a way of coding this so I can get thicker edges?

Thanks very much again.

Hello,

You would need to store it as an IRectangle and then call the Pen property on that.

//Draws a rectangle
IRectangle rectangle = DrawRectangle("tag1", true, 10, Low[10] - TickSize, 5, High[5] + TickSize, Color.PaleGreen, Color.PaleGreen, 2);
//changes the pen width to 4
rectangle.Pen.Width = 4;

Thanks very much again, Lance. As last time, it works a treat.

It's a shame that 'edge thickness' doesn't appear with the normal parameters, as it's so helpful, if not essential. Maybe this will be incorporated into NT8... We'll have to wait and see!

Cheers.
