got a strange result on High[iHighest(NULL,5,MODE_HIGH,30,0);] ---> The iHighest value is -1 on initialization
and High[] got error ---> array out of range ..
how can i result this issue , because iHighest is -1 . but i use backrest on mt4 built in ,it;s work well.

Hi Fenky,

You might want to refer to the MQL manual for answers to this. A brief look at the manual suggests -1 indicates an error which you will need to use GetLastError to determine what is causing it:

Hope this helps.
