i tried to programm this indicator.
double FirstValue = (Closes[1][0] * Instruments[1].MasterInstrument.PointValue);
double SecondValue = (Closes[2][0] * Instruments[2].MasterInstrument.PointValue);
Spread.Set(((FirstValue-SecondValue) / (SecondValue+FirstValue))*100);
SMA1Spread.Set(SMA(Spread,MA1Period)[0]);
SMA2Spread.Set(SMA(Spread,MA2Period)[0]);
Pal.Set(SMA1Spread[0] - SMA2Spread[0]);
double WillVal = WilliamsR(Pal, palPeriod);
