Floating-Point Division by Zero Error Message
This message may pop up in MultiCharts and/or portfolio Trader during your study calculation. Floating point error means that there is a division by a zero value in your code. It can be a variable, input, or a function in use that returns zero value. You need to identify this variable/input/function and make sure that the returned value is not zero.
You can use the Print keyword to output the values utilized in the script:
var: vrs(0); if vrs=0 then raiseruntimeerror("!!!alarm vrs=0"); if vrs<>0 then plot1(close/vrs) else plot1(0);
