Well, the parameters extraction happens on the browser and the code I wrote for this is not very capable, it doesn't really understand the MQL language. In this case I can see why the problem happens:

the code that I wrote thinks that the variable is defined on line 36 where this is clearly a string. In reality the variable is defined at line 20.
The correct values are:
data type => int
name => InpPeriodRSI
default value => 14
