so like this? for bollinger band (20,2)
am i heading in the right direction? thankyou again,
what does the '10' stand for?

set{my_avg, CEMA(20,10)}
set{sigma2, cstddev(20,10) * 2.0}
set{upper_band, my_avg + sigma2}
set{lower_band, my_avg- sigma2}

OR

set{my_avg, CEMA(bollinger band(20,2),10)}
set{sigma2, cstddev(bollinger band(20,2),10) * 2.0}
set{upper_band, my_avg + sigma2}
set{lower_band, my_avg- sigma2}

Giving it a try gets you kudos. What about this?

Fetcher[set{my_avg, cema(open,20)}
set{sigma2, cstddev(open,20) * 2.0}
set{upper_band, my_avg + sigma2}
set{lower_band, my_avg- sigma2}
draw my_avg on plot price
draw upper_band on plot price
draw lower_band on plot price
chart-length is 6 months

And you can add different filters to be more specific in what you might be searching for.
