Sljedećih 5 (od ukupno 6 spomenutih) značajki ulaznih vektora su:
    
    1. x1
    Relative Strength Index (RSI)
    A technical momentum indicator that compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions of an 
    asset.
    RSI=100-[100/(1+RS)]
    RS = (Avgerage of x days’ up closes) / (Average of x days’ down closes)
    
    2. x2
    Money Flow Index (MFI)
    This one measures the strength of money in and out of a security.
    Money Flow (MF) = Typical Price * Volume
    Money Ratio (MR) = (Positive MF / Negative MF).
    MFI = 100 – (100/ (1+MR))
    
    3. x3
    Exponential Moving Average (EMA)
    This indicator returns the exponential moving average of a field over a given period of time.
    EMA = [α *T Close] + [1-α* Y EMA].
    Where T is Today’s close and Y is Yesterday’s close.
    
    4. x4
    Stochastic Oscillator (SO)
    The stochastic oscillator defined as a measure of the difference between the current closing price of a security and its lowest low price, relative to its 
    highest high price for a given period of time.
    %K = [(Close price – Lowest price) / (Highest Price – Lowest Price)] * 100
    
    5. x5
    Moving Average Convergence/Divergence (MACD)
    This function calculates difference between a short and a long term moving average for a field.
    MACD = [0.075*EMA of Closing prices] – [0.15*EMA of closing prices]
    
    
    Još je dodano:
        Signal Line = 0.2*EMA of MACD

Napomene:
    1. Bolje je na engleskom da se ne izgubi nešto u prijevodu.
    2. 6. nije spomenuta u seminaru, morat ćemo smislit što uzeti (možda Tin zna jer nam je potrebno poznavanje burze i dionica :) ).
    3. Treća (x3) mi osobno nije jasna.
    4. Svaki x=(x1,x2,x3,x4,x5,x6) reprezentira jednu dionicu (mi ćemo uzeti 10-15 različitih) pa je n=6 i 10<N<15 tj imamo 10 do 15 primjera.
    5. Slobodne parametre pogađamo tj namještamo i/ili koristimo PSO.
    6. Vremenski raspon: oni su uzeli podatke svake dionice tj tvrtke u vremenskom periodu od 3 godine; jasno mi možemo drugačije npr zanemarit period kad je bila 
        kriza kao što smo pričali... Uzet neki vremenski period i izračunat potrebne indikatore za svaku dionicu (E TO TREBAMO ZA PRIPREMU!)
   
  Uglavnom, treba odredit vremenski period i odabrat x6 (to se trebamo dogovorit); ja moram sredit PSO i općenito vidjet koje ćemo parametre bez PSO-a al to tek na 
    kraju kad budem imala sve da ih mogu namjestit.
