This is an indicator built with ATR around a moving average, like a cloud.

You’ll need 2 indicators : Delta-Cloud (main one) and the Trailing stop ATR indicator which is necessary for calculation.

// Kevin Britains work
x = 10

a = AverageTrueRange[14](close)
up = low + (x+a)
dn = high - (x-a)

once trend=1
if high > up[1] then
 trend=1
elsif low < dn[1] then
 trend=-1
endif
if trend<0 and trend[1]>0 then
 flag=1
else
 flag=0
endif
if trend>0 and trend[1]<0 then
 flagh=1
else
 flagh=0
endif
if trend>0 and dn<dn[1] then
 dn=dn[1]
endif
if trend<0 and up>up[1] then
 up=up[1]
endif
if flag=1 then
 up= low + (x+a)
endif
if flagh=1 then
 dn= high - (x-a)
endif

if trend=1 then
 super=dn
else
 super=up
endif

return super as "Trailing Stop ATR"

and the main indi :

// Cloud Trend
// Kevin Britains

Trend1 = ExponentialAverage[75](close)

Trend2 = CALL "Trailing Stop ATR"[5]

if Trend1 > Trend2 then
 CloudUpper = Trend1
endif
if Trend2 > Trend1 then
 CloudUpper = Trend2
endif
if Trend1 < Trend2 then
 CloudLower = Trend1
endif
if Trend2 < Trend1 then
 CloudLower = Trend2
endif

return cloudUpper AS "DELTA UPPER",CloudLower AS "DELTA LOWER"
