Bollinger Band Shading in Tradestation

[dhelmin 10]

Hi:

Does anyone know if there is a way to shade in the area between upper/lower Bollinger Bands as shown in attached pic?

 

Thanks!

[Tams 20]

not with EasyLanguage.

 

:-(

[zdo 20]

see solidus's posts re shading etc on TS forums... it can be done...

[dhelmin 10]

Thanks ZDO. I think I'm missing something. The only thing I see is where he talks about paintbar colors. Is this what you are talking about?

 

Variables:

barColorText("White");

 

Condition1 = Close > Close[1];

Condition2 = Close < Close[1];

Condition3 = Close = Close[1];

 

If Condition1 then barColorText = "Green"

else if Condition2 then barColorText = "Red"

else if Condition3 then barColorText = "Yellow";

 

Plot1(barColorText, "Bar Color");

[Tams 20]

you can mimic painting the background by layering a thick bar behind the price bars as background color.

 

give this a try:

set the first 2 plots as "bar high" and "bar low".

 

inputs:
BollingerPrice( Close ),
TestPriceUBand( Close ),
TestPriceLBand( Close ),
Length( 20 ),
NumDevsUp( 2 ),
NumDevsDn( -2 ),
Displace( 0 ) ;

variables:
var0( 0 ),
var1( 0 ),
var2( 0 ),
var3( 0 ) ;

var0 = AverageFC( BollingerPrice, Length ) ;
var1 = StandardDev( BollingerPrice, Length, 1 ) ;
var3 = var0 + NumDevsUp * var1 ;
var2 = var0 + NumDevsDn * var1 ;

condition1 = Displace >= 0 or CurrentBar > AbsValue( Displace ) ;
if condition1 then 
begin
Plot1[Displace]( var3, "bar high" ) ;
Plot2[Displace]( var2, "bar low" ) ;
Plot4[Displace]( var3, "UpperBand" ) ;
Plot5[Displace]( var2, "LowerBand" ) ;
Plot6[Displace]( var0, "MidLine" ) ;


if Displace <= 0 then
	begin
	condition1 = TestPriceLBand crosses over var2 ;
	if condition1 then
		Alert( "Price crossing over lower price band" ) 
	else 
	begin 
	condition1 = TestPriceUBand crosses under var3 ;
	if condition1 then
		Alert( "Price crossing under upper price band" ) ;
	end;
	end ;
end ;

Thats exactly what I want to do for tradestation. Thank you!

 

I made an indicator with your code and on inputs typed high on testpriceUband and low on testpriceLband. It wouldn't accept bar high.

 

On the chart it just shows a regular Bollinger Band and doesn't show any shading. Any thoughts? thank you for your help!

[Tams 20]

you have to set these 2 plots as "bar high" and "bar low"

 

Plot1[Displace]( var3, "bar high" ) ; <--- set this as bar high

Plot2[Displace]( var2, "bar low" ) ; <--- set this as bar low

 

 

if you go to Format Study, you will see that I have entered the description of the 2 plots as "bar high" and "bar low".

[dhelmin 10]

I think I'm missing the part where you enter "bar high" "bar low". Under edit Easy Language its already there just as I copied from your code.

(mine is MultiCharts, TradeStation should be the same.)

[dhelmin 10]

Bingo! Now a new issue. How would I send the shading to the background? It is blocking out the high low close bars

[Tams 20]

right click on the chart... select Visual Order

[dhelmin 10]

I don't see anything like that on tradestation. i know what you mean though, there is a similar function in powerpoint

[monowheel 10]

I don't think you can control the drawing order in TradeStation, you'd have to redraw the candlesticks after BB bars.

[daedalus 10]

TS doesn't have visual order like MC. One of the archaic things about the platform that really shows its age.

and …

“You can have as many sets of barhi/barlo as you like, as long as the barhi preceeds its barlo. And plot1 is on top of plot2 which is on top of plot3, etc. And the first indicator applied is on top of the second, which is on top of the third...

 

Personally, I think shading is a really neat thing. It is much more logical for some sorts of things than lines or dots. I keep asking/hoping that TS will give us more tools to make it work better, e.g., fill between lines.”
