Dear Beerhunter and codersguru

My problem is solved after following your suggestion. Thank you very much for your reply titled "IMA and IMAOnArray" and "Problem in ind_buffer". I know how to program C++ before, but I face many difficulties in programming MQL4. I can't program my MACD sucessfully without your help. Let me say thanks once again.

Thank you very much.

Best Regards

Victor
