I thought this might be helpful. I found the original somewhere on the net and expanded on it. It should be noted that many of these commands should not be used because the MQL4 language provides better, cleaner, alternatives.

The biggest (greatest) ticket number always corresponds to the last (the newest) order of the account. Is it true ?  Ticket(order A) > ticket(order B) ---> Order A was opened after the order B was. Is it true ? 
It is inconvenient not able to modify the order magic number. The order comment, too. 
What folder which MQL4 keep history data ? Thank you
Hi, When testing EA's, are you more concerned about the max or relative drawdown, perhaps both? I think max drawdown is more important as this determines the drop from the "balance" whereas relative determines the drop from the "equity". This way I know what I could expect from the worst possible...
