How to make a simple experts advisors?

[[Deleted]]

Hello,

I am trying to build an simple experts advisors:

1. Change default chart from EURUSD,H1 to XAUUSD,H4.
2. At 6:00 everyday, auto add new order at XAUUSD, volume 2.

I think it's very simple but I don't know how to do. I have already studied and understood all of these:

• MQL4 Language for Newbies. Introduction
• MQL4 Language for Newbies. Difficult Questions in Simple Phrases

Please help me! Thank you!
