Multicharts Code - Outside Bollinger Bands

November 27th, 2015, 06:47 AM

Hello,

I am having a problem with my Multicharts Code, maybe somebody can give me advice please.

The "Squeeze" is working, but I would like to print a "!" over the bar, when the price closes 2 times over/under
the upper/lower Bollinger Band.

I created the Input "OutOfBands ( 2 )" and some variables, but I don�t see the "!" on the chart.

Here is my Code:

Code

{
November 2015
BBSqueeze Indicator
}

inputs:
BollingerPrice	( close),
Length			( 10 ),
NumDevsUp		( 1 ),
NumDevsDn		( -1 ),
NumBars		( 90 ),
OutOfBands		( 2 ),
SqueezeColor		( Yellow ),
TextSize		( 16 );

Variables:
Av			( 0 ),
SDev			( 0 ),
LowerBand		( 0 ),
UpperBand		( 0 ),
FixBollPrice		( 0 ),
Diff			( 0 ),
OutUpBand		( 0 ),
OutDnBand		( 0 ),
SignalUpBand		( 0 ),
SignalDnBand		( 0 ),
VertTxtP1 		( 2 ), // 0 - below the specified price value 
				// 1 - above the specified price value
				// 2 - centered on the specified price value
HorizTxtP1 		( 2 ), // 0 - to the right of the specified bar
				 // 1 - to the left of the specified bar
				 // 2 - centered on the specified bar
HiTxt 			(-1),
LoTxt 			(-1);
		
Av =  AverageFC ( Bollingerprice, Length );
SDev = StandardDev ( BollingerPrice, Length, 1 );
UpperBand = Av + NumDevsUp * SDev;
LowerBand = Av + NumDevsDn * SDev;
Diff = UpperBand - LowerBand;

if Close > UpperBand then
	OutUpBand = OutUpBand +1
	else
	OutUpBand = 0;
if close < LowerBand then
	OutDnBand = OutDnBand +1
	else
	OutDnBand = 0;
	
if OutUpBand = OutOfBands then
	HiTxt = text_new(date,time,high +1 ,"!");
	text_setcolor(HiTxt,white);
	text_setsize(HiTxt,TextSize);
	text_setstyle(HiTxt, HorizTxtP1,VertTxtP1); 

if OutDnBand = OutOfBands then
	LoTxt = text_new(date,time,high +1 ,"!");
	text_setcolor(LoTxt,white);
	text_setsize(LoTxt,TextSize);
	text_setstyle(LoTxt, HorizTxtP1,VertTxtP1); 

Plot1 ( UpperBand, "Upperband");
Plot2 ( LowerBand, "Lowerband");
Plot3 ( Av, "Av");

If Diff <= Lowest ( Diff, NumBars ) then
begin
	SetPlotColor ( 1, Squeezecolor );
	SetPlotWidth ( 1, 3);
	SetPlotColor ( 2, Squeezecolor );
	SetPlotWidth ( 2, 3);
	Alert (Getsymbolname + "Squeeze" );
End;

Any idea what is wrong or missing?

Thank you.

Best regards,
Tim

Hi Tim,

I just tested your code and I get quite a lot "!" symbols on a 5 min @ES#. There are two potential issues that I can think of at the moment: 1. you are using a symbol where 1 point represents a large move (like a Forex symbol for example). 2. Your background color for the chart happens to be white which would be the same color as the exclamation marks.

When you right click on the chart and go to "Format Drawings" you should see several text objects in the list.

Hi ABCTG,

thank you, the white color was the problem! Sometimes it is so easy....

I have found another Problem. When I plot the Bollinger Bands with my Indicator and add another Bollinger Band
Indicator from Multicharts I have 2 different plots in the Chart window. But in the Data Window I have the same correct numbers.

Whats wrong here?

Thanks.

Best regards,
Tim

Tim,

that's most likely a scaling issue. When you check the Scaling tab under Format Study for each indicator both should be set to "Same as Instrument".

Good morning ABCTG,

I tried over the weekend to change my code, but unfortunately I don't found a solution.

I plot "!" on the chart when the variable OutUpBand = OutOfBands:

Code

if OutUpBand = OutOfBands then
	HiTxt = text_new(date,time,high +1 ,"!");
	text_setcolor(HiTxt,white);
	text_setsize(HiTxt,TextSize);
	text_setstyle(HiTxt, HorizTxtP1,VertTxtP1);

Now I would like to print instead the "!" the value of the variable "OutUpBand".

Is this possible? How can I realize that?

Thank you.

Best regards,
Tim

Hi Tim,

you need to convert a numerical variable to a string using the reserved word NumToStr. Then you can draw this string on the chart.

Code

if OutUpBand = OutOfBands then
begin //using the begin here to include all text related reserved words in the check
	HiTxt = text_new(date,time,high +1 , NumToStr( OutUpBand, 0 ) ) ;
	text_setcolor(HiTxt,white);
	text_setsize(HiTxt,TextSize);
	text_setstyle(HiTxt, HorizTxtP1,VertTxtP1); 
end ;
