Hi guys.
I looked around this forum and saw some people who made there own EA.
Can you direct me to a giude or some site where I can learn to do that my self?

Thanks a lot =]

hard to say really.

do you have any experience in prior programming?

if you know c++ it will be much easier.

I learned Java at school so I have a very nice basics.

By the way, I found the program Forex EA Generator 2, and started to use it but I had some trouble you can see here hope you can help me with it:

Do a google search for mql4 documentation, there is a pretty limited library available to you in an EA, so it’s pretty easy to figure out based on the documentation if you already have any programming experience.

5

Okay ill do that.
But do you have any idea how to help me with the problem I linked in the last post?

6

First, what is the type of your reader variable?

Second, can you post the line where you call OrderSend() ? Without seeing that, I have no idea why you’re getting error 130 (which is for invalid stops, per the MQL documentation).

Okay, I think I should explain my self a bit better.
I wanted to know how to make your own EA. So I search on google and youtube and realise that its actually language that very similar to Java but not exactly the same.

Then I found this video about a program that write the EA for you - like
"Forex EA Generator 2" that I correctly use (by use I mean trying to lean how to use it).

The EA I wanted to create is for a trading system that some guy post here -
forums.babypips.com/free-forex-trading-systems/35626-simple-gbpusd-strategy-no-indicator-needed.html

So to sum up, I need help creating that EA for that System - especially how to check the High and Low values on spacific time rang (in case of that system - between 21:00 to 10:00).

Thanks for reading !

Don’t use an EA generator for that, that system should be really easy to put into an EA. Adding the extra layer of the code generator will just be adding complexity and opening yourself to errors. All of the things you need to know will be in the MQL4 documentation (I would post a link, but I’m not quite to 50 posts yet).

First, thanks for your reply.
You can post a link - just remove everything from the http to after “www”.

10

You shoud also check out the tutorials written by tradersguru (he posts in all the usual places)

There’s a tutorial on building EA’s, and of course loads of stuff on mql4.com

11

Can you post the spacific link for this turorials?
Its just that I found a lot of places with info but I dont know what to choose.

Thanks !!

12

the tutorials are in PDF format from here.

MT4 programming resources @ Forex Factory

and probably 1001 other places too

13

tried it once, found it really hard.

15

book.mql4.com/
If you have java basics, should be quite simple.

16

The best way might be to look for free, open-source EAs and use them as references.

Depending on your needs, it may not require much more than cutting and pasting code blocks into your personal EA.

17

Thanks guys I’m using the site docs.mql4.com and it just fine for someone who already have Java basics =]

18

tutorials, but who is making it for me and its serious?

for example i have a good mechanical system that works. and i would like to make it automatic. i have no idea of programing such things.

If you want to learn how to write your own EA’s and indicators start here.

too difficult for moi.

Get a hold of me Holder - -
I need a good system to program. We can hash out the details together.
