oscillator code not working, numerical expression expected here

Hi, I am new here and I am enjoying reading these posts, learning a lot. thanks for it

I am trying to convert code from Pine Script to TradeStation easy langauge, all is fine except I am getting error near

HTML Code:

s = s + (close > open[ss]) - (close < open[ss]);

HTML Code:

inputs: 
double length(14), 
double calcLength(5), 
double smoothLength(3);

vars: 
double s(0), 
double MA(0), 
double Main(0), 
double Signal(0), 
double ss(0),
double len(0);

len = length;

s = 0;
for ss = 0 to (len - 1) begin
    s = s + (close > open[ss]) - (close < open[ss]);
end

MA = XAverage(s, calcLength);
Main = XAverage(MA, smoothLength);
Signal = XAverage(Main, smoothLength);

plot1(Main, "Main", iff(Main > Signal, green, red));
plot2(Signal, "Signal", iff(Main > Signal, green, red));
plot3(0, "ZeroLine", gray);

plot4(length, "UpperLine", red);
plot5(-length, "LowerLine", green);

plot6(length * 0.7, "Overbought", gray);
plot7(-length * 0.7, "Oversold", gray);

fillPlot(plot4, plot5, "Range", iff(Main > Signal, green, red), 90);
fillPlot(plot6, plot4, "Overbought", red, 90);
fillPlot(plot7, plot5, "Oversold", green, 90);

I can not seem to understand where its going wrong, any help would be very appreciate it

Thanks a lot in advance

This part doesn't translate to a numerical expression. With other words, doesn't translate to an actual number:

(close > open[ss]) - (close < open[ss]);

What are you trying to do here?

So, I think you are trying to add 1 when close is greater than open and subtract 1 when close is less than open. One way of doing it is to change this:

Code

   s = s + (close > open[ss]) - (close < open[ss]);

to this:

Code

    s = s + IFF(close > open[ss],1,0) - IFF(close < open[ss],1,0);

btw, you also have other issues in your code. "Gray" is not a recognized color in EasyLangauge. darkgray is. I am also not sure about fillplot.

Thanks a lot for the help, yes indeed after long review i discovered that I forgot to implement the "if" statement, and was confused about the error becuz I thought I did.
