How do you create an indicator in ToS such that the BB is for the MACD?

Hi I am using ToS and im trying to add Bollinger Bands to my MACD indicator. Does anyone knows how to do it?

The calculation for the BB is taken from the MACD indicator instead of the stock's price

@tandeshao Try this code:

declare lower;
#---------- MACD Inputs
input fastLength = 12;
input slowLength = 26;
input macdLength = 9;
input macdAverageType = AverageType.EXPONENTIAL;
#---------- BB Inputs
input displace = 0;
input length = 20;
input num_Dev_Dn = -2.0;
input num_Dev_up = 2.0;
input bbAverageType = AverageType.Simple;
#---------- MACD Section
def value = MovingAverage(macdAverageType, close, fastLength) - MovingAverage(macdAverageType, close, slowLength);
def avg = MovingAverage(macdAverageType, value, macdLength);
#---------- BB Section
def sDev = stdev(data = avg[-displace], length = length);
plot midLine = MovingAverage(bbAverageType, data = avg[-displace], length = length);
plot lowerBand = midLine + num_Dev_Dn * sDev;
plot upperBand = midLine + num_Dev_up * sDev;

Credit goes to Hahn.
