Std Dev Zones for Indicators

[Scott1341@xxxxxxx]

Anyone know how to substitute a MACD for the RSI shown below (to make it 
similar to the strength bands found on the MACD Oscillator in Advanced GET). 
Please respond directly to: scott1341@xxxxxxx (as well as to the group). 
Thank you.

Input: len(9),ave(30),sd(2),devlen(30); 
Plot1(Rsi(c,len),"rsi"); 
Plot2(average(rsi(c,len),ave) + sd * StdDev(rsi(c,len),devlen),"top");
Plot3(average(rsi(c,len),ave) - sd * stddev(rsi(c,len),devlen),"bot");
