[Help] MQL4 code translation

[wangmingming2003-cn]

Hello, Everyone,

I am trying to translate a index used in stock market, although I also write it in MQL4 language, but it doesn't work.

I made notes for the original syntax, please help.

[code]
RSV:=(CLOSE-LLV(LOW,5))/(HHV(HIGH,5)-LLV(LOW,5))100; --CLOSE is the close price for the period. HHV is the highest value of the "Highest Value" in the timeframe(in this case, the time frame is 5); And LLV is the lowest value of the "lowest Value" in the timeframe.
K0:=SMA(RSV,3,1); --SMA（x,N,M), the M days moving average；M stands for the weight；for example Y=（xM +(N-M)Y'); Y'is the previous period's SMA；
K:=K0;
D:=SMA(K0,2,1);
J1:(3K0-2D),COLORYELLOW;
J2:MA(J1,2),COLORRED;
MAV:=(2C+H+L)/4; ---C is the latest CLose price；H is the latest Highest Price；L is the latest Lowest price.；
VAR1:=LLV(LOW,21); --the smallest price in the past 21 periods' lowest price
VAR2:=HHV(HIGH,21);--the biggest price in the past 21 periods' highest price
SK: EMA((MAV-VAR1)/(VAR2-VAR1)100,8),COLORWHITE; --EMA is the exponential moving average
SD: EMA(0.667REF(SK,1)+0.333*SK,1),COLORCYAN;

SJ:=3SK-2SD;
50,POINTDOT,COLORRED;
70,POINTDOT,COLORRED;
90,COLOR00AA00;
WWW:SJ<20,COLOR00AA00;
IF(WWW,0,20),COLOR00AA00,LINETHICK2;
[/code]

here is what I wrote in MQL4:
