New comment
 

Hi, Could someone please help to explain why below array assignment is wrong

And what is the correct way of doing it

many thanks in advance.

double bandU    =iBands(NULL, 0, 20, 2, 0, PRICE_CLOSE, MODE_UPPER, 0);
double bandM    =iBands(NULL, 0, 20, 2, 0, PRICE_CLOSE, MODE_MAIN, 0);
double bandL    =iBands(NULL, 0, 20, 2, 0, PRICE_CLOSE, MODE_LOWER, 0);
        
double MA5      =iMA(NULL, 0, 5, 0, MODE_EMA, PRICE_CLOSE, 0);
double MA20     =iMA(NULL, 0, 20, 0, MODE_EMA, PRICE_CLOSE, 0);
double MA120    =iMA(NULL, 0, 120, 0, MODE_EMA, PRICE_CLOSE, 0);
double MA200    =iMA(NULL, 0, 200, 0, MODE_EMA, PRICE_CLOSE, 0);

double arrayvalue[7]  ={bandU, bandN, bandL, MA5, MA20, MA120, MA200};

Welcome to the looking-glass world of MQL4, similar but subtly different to languages which I suspect you're used to writing in. You can't initialise arrays in MQL4 with variables, only with constants.
 

thank you jjc :)
