Moving Average Envelope
The Moving Average Envelope adds a parallel line above and below a moving average using a given percentage of the price. These lines can be useful for identifying short term price fluctuations. The user may change input (close), method (EMA), period, shift and deviation values. This indicator’s definition is further expressed in the condensed code given in the calculation below.

Calculation
//input = price, user defined, default is close
//method = moving average (ma), user defined, default is EMA
//period = user defined, default is 20
//shift = user defined, default is 0
//topDev = percent, user defined, default is 2.5
//bottomDev = percent, user defined, default is 2.5
//LT = less than, LOE = less or equal
latest = size()-1;
end = latest;
if (shift LT 0) end -= shift;
topDev = topDev/100;
bottomDev = bottomDev/100;
// Calculate top and middle and bottom lines
for(int i = period; i LOE end; i++)
ma = ma(method, i, period, input);
Plot1: top[i+shift] = ma + topDev * ma;
Plot2: middle[i+shift] = ma;
Plot3: bottom[i+shift] = ma - bottomDev * ma;
