reduced and condensed version of ATLAS Blai5 indicator to incorporate as a minimum bar to inform us of the values that are giving ATLAS signal.
ATLAS Mini gives signal when we have a mathematically significant narrowing of the Bollinger Bands (BB). It is well known that the narrowings in the BB are usually a prelude to sudden movements upward or downward. ATLAS says these figures as a warning sign.
(explanation translated from spanish).

dbb = SQRT((BollingerUp[20](close) - BollingerDown[20](close))/ BollingerUp[20](close)) * 20
dbbmed = ExponentialAverage[120](dbb)
factor = dbbmed * 4/5
atl = dbb - factor
if atl > 0 then
al1 = 0
else
al1 = 1
endif
return al1 as "ATLAS Mini"
