Keltner channel/ Bollinger Band Cloud

[arod49]

Does anyone know how to add a custom color cloud to fill in the Bollinger Band/Keltner Channel? thanks

Try this:

#

input price = close;
input displace = 0;
input length = 20;
input Num_Dev_Dn = -2.0;
input Num_Dev_up = 2.0;
input averageType = AverageType.Simple;

def sDev = stdev(data = price[-displace], length = length);

plot MidLine = MovingAverage(averageType, data = price[-displace], length = length);
plot LowerBand = MidLine + num_Dev_Dn * sDev;
plot UpperBand = MidLine + num_Dev_Up * sDev;

LowerBand.SetDefaultColor(GetColor(0));
MidLine.SetDefaultColor(GetColor(1));
UpperBand.SetDefaultColor(GetColor(5));

AddCloud(UpperBand, Midline, Color.Green, Color.Green);
AddCloud(LowerBand, Midline, Color.Red, Color.Red);

thank you very much

@BenTen This is great! Is there a way to make the cloud change colors? Like green when price is above mid line and red for below?

@army11b1980 Sure, code above has been updated.

Anyone have/able to create something like the TradingView Bollinger Bands so that is has the cloud look to it? I found one deep on reddit but it was shaded red/green and couldn’t change the colors.

@BenTen The AddCloud() lines only paint the top and bottom different colors, not trending colors... I've been working on a BollingerBand indicator and haven't been able to make the cloud paint properly... I tried looking at MomentumKeltnerChannels by @Pensar but my brain just isn't in the game this evening... Banged my head earlier and must have jarred some dust loose in there... Any help would be greatly appreciated...

@rad14733 I believe you can only assign one color to each cloud. Is that what you were asking about?

No... MomentumKeltnerBands does trending colors, UpTrend and DownTrend... The issue is the BollingerBands and KeltnerChannels never do a crossover so the code needs to be faked out into trending... I've been plugging away at it... If I figure it out I'll post my findings, but if anyone has a fix for this I'd greatly appreciate it because then I can move on to other things...

@rad14733 The Bollinger Bands will expand along as price continues its uptrend or downtrend, so it's definitely different from the MomentumKelterBands. With the MomentumKelterBands, the price can move far away from it in either direction.

Yep... And I'm working on a "Skinny_BollingerBands" study at the moment... I just found a BB script that changes trend colors so now I just need to figure out how they did it and replicate the logic in my study... My logic on this is to have a variable noise zone for less false entries... Just an idea I had and felt the need to play with...

Edited to add: Actually, the code I found was the FW_MOBO code that @Pensar used in MomentumKelterBands...

Hi,
Can someone help me setting a background color for Bollinger Bands on TOS? Thank you.

@mts1240 Welcome to the usthinkscript forums... Which version of the Bollinger Bands are you currently using...??? If you are using the code in Post #2 above then you could use the following code if you want the entire Bollinger Band background the same color... Notice the changes to the last two lines of code in comparison the the code in Post #2... For more information on clouds, refer to AddCloud() in the Thinkscript Learning Center...
