Original LUA indicator: viewtopic.php?f=17&t=61115.
Formulas: Central[i] = ((2-Alpha)mt[i]-ut[i])/(1-Alpha), Top[i] = Central[i]+Deviationdt2, Bottom[i] = Central[i]-Deviationdt2, where mt[i] = AlphaMedian+(1-Alpha)mt[i-1], ut[i] = Alphamt[i]+(1-Alpha)ut[i-1], Median = (High+Low)/2, dt2[i] = ((2-Alpha)mt2[i]-ut2[i])/(1-Alpha), mt2[i] = AlphaAbs(Median-Central[i])+(1-Alpha)mt2[i-1], ut2[i] = Alphamt2[i]+(1-Alpha)ut2[i-1], Alpha = 2/(1+Lenght).
