How do I sort out this array out of range error?

[Peter Kaiza]

  double closeh4x[];
   ArraySetAsSeries(closeh4x,true);
   CopyClose(_Symbol,PERIOD_H4,0,30,closeh4x);
    double close26h4x=closeh4x[26];
 //================

The error relates to the close price of the last 26th candle and states ' Array out of range' How do i fix this?

CopyClose(_Symbol,PERIOD_H4,0,30

1. You asked for thirty (30) values. You didn't check if you got that many.

   Check your return codes, and report your errors. Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

2. On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

   On MT5: Unless the chart is that specific pair/TF, you must synchronize the terminal Data from the Server before accessing candle/indicator values.
