RSI w/ Bands question

[dianeparson]

Could someone help me create a band to add to this indy that calulates the difference between the upper BB and Lower BB.

var vLower = study2.getValue(BollingerStudy.LOWER);
vDiff=study2.getValue(BollingerStudy.UPPER)-study2.getValue(BollingerStudy.LOWER);


return new Array(vUpper, vBasis, vLower, vRSI, vDiff);

Is what I would do
