0 based RSI Histogram

[emorrison]

Hi,

I am trying to create a RSI efs that uses 0 instead of 50. I do not receive a syntax error but the histogram will not display. Can anyone see what I am doing wrong?


var rsi = rsi(14)-50;
function preMain() {
setStudyMin(-100);
setStudyMax(100);
setStudyTitle("Zero Based RSI");
setCursorLabelName("ZeroRSI");
setDefaultBarFgColor(Color.blue, 0);
setPlotType(PLOTTYPE_HISTOGRAM,0);

}
function main() {
return rsi;
}

The reason why your script is not returning anything is because you placed your equation outside of the main() function where it will be executed only on the first iteration of the script when the formula is loaded or reloaded in the chart
To resolve this replace the return statement ie
return rsi;
with the following
return rsi(14)-50;
and delete the first line of your script where you assign your calculations to the variable rsi. As an aside you should not name variables using reserved keywords such as names of existing functions etc
Once you make this change the formula will work
