if the EA run,will detect all array display to main window?
 

Does that compile?

Shouldn't you be putting some values in the iMA call?

double mapra1=iMA(Symbol(),0,MAperiod1,ma_shift,ma_method,ma_applied_price,x);

and you should use NULL, not Symbol()

Please do not double post ! https://www.mql5.com/en/forum/146186

Symbol() is OK!!

Are you running this for each tick ? or once per bar ?
  
 for(x=1;x<=统计周期;x++)
                           {
                              double mapra1=iMA(Symbol(),0,MAperiod1,ma_shift,ma_method,ma_applied_price,x);
                              double mapra2=iMA(Symbol(),0,MAperiod2,ma_shift,ma_method,ma_applied_price,x);
                              double mapra3=iMA(Symbol(),0,MAperiod3,ma_shift,ma_method,ma_applied_price,x);
                              double mapra4=iMA(Symbol(),0,MAperiod4,ma_shift,ma_method,ma_applied_price,x);
                              double BBIC=((mapra1+mapra2+mapra3+mapra4)/4);
                              BBI[i+x]=BBIC;
                           }

Your x is atleast 1, so why do you calculate this every tick same bar ??

the,MAperiod1 is not same

I just need the last one K line 's VALUE,not need every line

Perhaps you could answer the question ?
