Load history to table/array

[RDfx]

I want to load data history to table/array but I don't know how to do. Can you help me, and explain each step of program ? I'm an amatteur. 

Others, I want to get result in Alert tipps for verifying date and closed price . Thanks.

Have you tried using ArrayCopyRates() ?

1. If you're asking about your own array, look at https://www.mql5.com/en/forum/138127

2. RaptorUK: Have you tried using ArrayCopyRates() ?
   

   Such as:

   #define ACR_TIME     0  // Array Copy Rates
   #define ACR_OPEN     1
   #define ACR_LOW      2
   #define ACR_HIGH     3
   #define ACR_CLOSE    4
   #define ACR_VOLUME   5
       #define ACR_COUNT   6
   double  acr.arr[][ACR_COUNT];
   int init(){
     :
           // https://forum.mql4.com/36470/page2 says ArrayCopyRates is a non-
           // reentrant, non-thread-safe call. Therefor you must put a mutex around
           // the call in case of multiple EAs on multiple charts. Alteratively,
           // since init() is single threaded across all charts, put all ACRs there
           ArrayCopyRates(acr.arr, chart.symbol, Period());        // I'm in Init.
   }
   int      GetBars(){                 return( ArrayRange  (acr.arr, 0   ) );  }
   int      iGetShift(datetime tm){                #define iCB 0   // Current Bar
       int iLimit = GetBars();                     #define iPB 1   // Previous Bar
       for (int iTm=iCB; iTm < iLimit; iTm++)  if (GetTime(iTm) <= tm) return(iTm);
       return(iLimit-1);
   }
   double   GetVal(            int eACR, int iBar=iCB){ return( acr.arr[iBar][eACR] ); }
   datetime GetTime(  int iBar=iCB){       return( GetVal(   ACR_TIME,   iBar) ); }
   //double GetOpen(  int iBar=iCB){       return( GetVal(   ACR_OPEN,   iBar) ); }
   double   GetHigh(  int iBar=iCB){       return( GetVal(   ACR_HIGH,   iBar) ); }
   double   GetLow(   int iBar=iCB){       return( GetVal(   ACR_LOW,    iBar) ); }
   double   GetClose( int iBar=iCB){       return( GetVal(   ACR_CLOSE,  iBar) ); }
   //double GetVolume(int iBar=iCB){       return( GetVal(   ACR_VOLUME, iBar) ); }
