Boxes

[cptrader]

I have been trying to find a way of placing a highligh box around a bar for a certain condition. At the moment all I can do is create a boxwhose edges are on the main body of the bar. I have attached a screen shot of what I mean. I have also placed an insert from another program that does what I wish

if (CrossBelow(SMA(Close, 8), SMA(Open, 8), 1))
DrawRectangle("My rectangle"+ CurrentBar , 1, Low[1] - 2 * TickSize, 0, High[0] + 2 * TickSize, Color.Orange,BackColor,2);
}

The code above is what I have used. Can you suggest a way to alter code to achieve what I am looking for.

Hi cptrader, basically you look for a way to center the rectangles. Easiest would be to color your conditions by changing the BarColor and then uppen the thickness of the bar...

[cptrader]

Thanks for your reply
Not entirely sure what you mean.
I have added code to change colour but not sure how to change the thickness.Are you saying that if condition bar is thicker then the boxes will be off centre?

if (CrossBelow(SMA(Close, 8), SMA(Open, 8), 1))
{BarColor = Color.Blue
DrawRectangle("My rectangle"+ CurrentBar , 1, Low[1] - 2 * TickSize, 0, High[0] + 2 * TickSize, Color.Orange,BackColor,2);
}

You cannot create a box that has anchor points not on the center line of a bar. What you can try is outlining the bar via a box that encompasses the prior bar and the next bar.

If this is unacceptable your only option is to override the Plot method and this is unfortunately advanced C# programming that we cannot offer support for.

[cptrader]

Were you suggesting using CandleOutlineColor = Color.Purple; and thickening it

Can you please explain how to increase thickness of an individual bar or the candle outline

[NinjaTrader_Josh]

No that was not what I was suggesting. I was suggesting you to use your DrawRectangle. CandleOutlineColor does not change width. It changes color.

I can offer you another way to achieve what you want avoiding overrinding plot method.

You can draw a line on the bar you want to highligh, just set line width more than bar width and set color opacity to the level you want.

This way has a downside - "box" width won't change if you change x scale until you refresh indicator (f5). If this does not suit you - the only way remaining is to override the plot method.

Attached is simple example.
Hope it helps

Great suggestion roonius! Thanks.

[cptrader]

This was exactly the solution I was looking for. Thanks roonius

Just a few clarifications with code

Firstly

Color myColor = Color.FromArgb(50,0,0,255);

Can someone clarify what the inter imputs stand for?

DrawLine("line"+CurrentBar.ToString(),0,Low[0]-TickSize,0,High[0]+TickSize,myColor,DashStyle.Solid,
ChartControl.ChartStyle.GetBarPaintWidth(ChartCont rol.BarWidth)+2);

GetBarPaintWidth(ChartControl.BarWidth)+2);

Can some please explain this function? I have altered the integer value (2) but there appears no change to chart.appearance.

Argb = alpha red green blue

Unfortunately we cannot offer support for ChartControl.

[cptrader]

Ok. How can you use argb to set color opacity to the level you want.
Is there other ways to select opace colours?


Thanks

That is a very elegant solution and so simple!
Brilliant.
