Just might come in handy. :-)
Don't mind if you put it out there :-) :-)
 
Hello
Can you tell me if there is any "office" that provides its own server for testing EAs. That is, I upload my EA to their server, where it is tested in "on line" mode on a demo account.
 
KimIV:

Warning! In my post of 12.03.2008 07:24 I have changed the attachment SetOrder.mq4

I've tried your code, but it didn't work (maybe my hands are wrong :( ... ). When compiling shows a lot of errors.
Message' - the function is not defined - what is it?
'break' - 'break' or 'continue' used within some cycle only - what is wrong with loops?
'GetNameTF' - function is not defined - how to define it?
...etc. :(
I still can't figure it out. Please help me, if you're not in trouble.

Ignore the break for now. Sort out the function descriptions first.

}

Look for the ExistOrders function in this thread. I have already posted it. ErrorDescription is plugged in with the compiler directive:

#include <stdlib.mqh>

Okay, there is still the GetNameOP function:

Okay, there's still the GetNameOP function left:


I feel like I should put the libraries (both of them) out there and do some outreach. The libraries will not be refused.
 
Thank you - very helpful, but there are other problems again... :(
now all these functions show - Function "ххххххххх" is not referenced and will be removed from exp-file
maybe I put them in the wrong place... :( I hope you can help.
..it's hard for a beginner in MQL4 :)

I'll probably post it... but not before we've gone through all the features... otherwise what am I here for? Put it on codebase, people would download it and forget about it. I'm like that myself :-) I've got a bunch of other people's code lying around untouched. And when you have the opportunity to probe, ask questions, it's quite another matter.

SZY. My files with prefix test_ compile and run fine.

Look how everything is put together in test_SetOrder.mq4
 



If I understand correctly, replacing OrderSend with OrderModify

can be used when modifying an order?
as well as when closing... ??

...but how can we combine these functions in one function?

also...

if (mn<0 || OrderMagicNumber()==mn)

why mn<0 ? can't Magic be negative?

but how to combine this into one function so it doesn't repeat itself?

Later on there will be a function to modify

it can... But in my EAs, I only use positive Magic in YYYYMMDD format, e.g., 20080323. This is the date when the EA was developed.
