Im trying to create an indicator that has a standard relative strength study, combined with a moving average and SPX overlay like the picture attached.

ANy help would be greatly appreciated.

See if this helps you.

declare lower;
Input symbol = close;
Input symbol_2 = “spy”;
input slowLength = 50;
input fastLength = 200;
Plot ratio = (symbol) / close(symbol_2);
ratio.AssignValueColor(if ratio >= ratio[1] then Color.UPTICK else Color.DOWNTICK);
input averageType = AverageType.ExPONENTIAL;
plot FastAvg = MovingAverage(averageType, Ratio, fastLength);
plot SlowAvg = MovingAverage(averageType, Ratio, slowLength);

Ratio.DefineColor("Up", Color.UPTICK);
Ratio.DefineColor("Down", Color.DOWNTICK);
Ratio.AssignValueColor(if Ratio >= Ratio[1] then Ratio.Color("Up") else Ratio.Color("Down"));

SlowAvg.SetDefaultColor(GetColor(4));

Ratio.DefineColor("Up", Color.UPTICK);
Ratio.DefineColor("Down", Color.DOWNTICK);
Ratio.AssignValueColor(if Ratio >= Ratio[1] then Ratio.Color("Up") else Ratio.Color("Down"));
FastAvg.SetDefaultColor(GetColor(1));
SlowAvg.SetDefaultColor(GetColor(4));
