BOLLINGER BANDS, apply to another custom indicator ?

 
HELLO>

How can i apply bollinger bands to another indicator, on the same chart?

-I have this indicator which gives me the ratio for (EURUSD/USDCHF), i use this ratio for pair-trading.

-I want to determine bollinger bands: upper band, mean, lowerband from the ratio indicator. Is this possible with EA?

-I'm already using MATLAB to perform bollinger bands calculations on the ratio price but i cannot interface matlab with EA.

-Bollinger Bands Indicator applied to another custom Indicator?
