LongL Double 25 5 100
Short L Double 13 2 100
SignalL Double 8 2 100


here is the rest of the formula


diff:= close - Ref(close,1);
doubleSmoothedAbsDiff:= EMA( EMA( Abs(diff), longL), shortL);

TSI: if (doubleSmoothedAbsDiff == 0 ,0,
(( EMA( EMA( diff, longL), shortL)) / doubleSmoothedAbsDiff)*100),Colorstick;

Signal: EMA( TSI, signalL),Width2,ColorBlue;

UZ :MA(TSI, 30) + (1.3185 * StD (TSI, 30)),Width2,ColorViolet;
LZ: MA(TSI, 30) - (1.3185 * StD (TSI, 30)),Width2,ColorViolet;
