Can someone please show me how to add a 50 bar simple moving average to the following relative strength script that is found in TOS:


declare lower;

input CorrelationWithSecurity = "SPX";
def close2 = close(CorrelationWithSecurity);

plot RS = if close2 == 0 then 0 else close/close2;
RS.setDefaultColor(GetColor(6));

def sr = CompoundValue("historical data" = RS, "visible data" = if isNaN(sr[1]) then RS else sr[1]);
plot SRatio = sr;
SRatio.setDefaultColor(GetColor(5));

Hi, this seems to work. You can adjust the length and type of moving average if needed. The additional code is shown in bold.

Best of luck to you.

# RelativeStrength_with_MA

declare lower;

input length = 50;
input averageType = AverageType.Simple;
input CorrelationWithSecurity = "SPX";
def close2 = close(CorrelationWithSecurity);

plot RS = if close2 == 0 then 0 else close/close2;
plot RSavg = MovingAverage(averageType, RS, length);

RS.setDefaultColor(GetColor(6));
RSavg.setDefaultColor(Color.RED);

def sr = CompoundValue("historical data" = RS, "visible data" = if isNaN(sr[1]) then RS else sr[1]);
plot SRatio = sr;
SRatio.setDefaultColor(GetColor(5));
