A request that was addressed to ProRealTime: Hello, I would an indicator that tells me when the %K cross with %D of Stochastic smoothed (17,9,3) a=Stochastic smoothed (17,9,3)%K b=Stochastic smoothed (17,9'3)%D condizione1=a>b condizione2=a<b if condizione1 then c=1 elsif condizione2 then c=-1 endif return c Suggestion for an anwser: nbperiode=14 PeriodeK=3 PeriodeD=5 a=SmoothedStochastic[nbperiode,PeriodeK](close) b=average[PeriodeD](a) condizione1=a>b condizione2=a<b if condizione1 then c=1 elsif condizione2 then c=-1 endif return c
