Ok, that script has more errors than lines. So, some more reading of the tutorial might be required. Let's start with the first error that you get when running that script:

Error in 'line 13:
EMA(): Pointer expected
< var Qqe = series(EMA(Rsi,SF)); >

There is apparently something wrong with the parameters to that EMA call. I can tell you that it's the "Rsi" series. Look how you have defined it:

var Rsi = series(RSI(series(priceClose()),RSI_Period));

What is wrong here? How do you define a series?
