RSIColorLineBar.efs question

[shaeffer]

I tried to use the RSIColorLineBar.efs from the Helpers Directory, but whether I left the length at the conventional 14 periods, or changed it to 8 periods (my preference), I could not get the RSI curve created by this efs to match the basic RSI study.

Any idea why these curves do not match? Does "/library/RSIStandard.efs" calculate a different RSI?

-------------------------------------------

Instead, I tried to merge the setBarBgcolor commands from the RSIColorLineBar.efs into the builtinRSI.efs, but could not figure out where to get vValue from. The comments say "Use vRSI.getValue(RSIStudy.RSI) for your code", but how? Any help with this would be appreciated.

Hello Shaeffer,

The RSI Study in the Basic Studies menu uses and exponential moving average calculation. For comparison, use \Library\RSIEnhanced.efs.

The RSIColorLineBar.efs uses the \Library\RSIStandard.efs, which is based on a simple moving average calculation.

If you want, you can change the RSIColorLineBar.efs to use the RSIEnhanced.efs instead.

I did the above, and it worked. Thanks Jason.

I can readily see how the last grouping of commands in the above efs controls the colors. As a learning experience (since I tried and failed), if I copied those commands into the builtinRSI.efs, how would I get the builtinRSI.efs to recognize vValue?

Hello Shaeffer,

The vValue variable needs to be instantiated with the var keyword and have the value of vValue set to vRSI.getValue(RSIStudy.RSI). Change the return statement in the builtinRSI.efs and add the following code.

var vValue = vRSI.getValue(RSIStudy.RSI);
if (vValue == null) return;

if(vValue >= 70) {
    setBarStyle(PS_SOLID);
    setBarThickness(2);
    setBarFgColor(Color.black);
    setBarBgColor(Color.red);
} else if(vValue <= 30) {
    setBarStyle(PS_SOLID);
    setBarThickness(2);
    setBarFgColor(Color.black);
    setBarBgColor(Color.lime);
}

return (vValue);
