login to an account using EA

New comment
 

Can I use an EA to auto-login different accounts?

if i have sereral different accounts,and i want to trade with all of them,can i first login with one account,send orders,then login with another account and send the same orders?

 

I've seen in russian forum here someone achieved that with DLL calls

but I don't have a link and can't find it right now

Поместите нужные вам торговые счета (можно разных ДЦ) в закладку Избранное окна Навигатор.

Запустите скрипт, указав количество торговых счетов в закладке Избранное окна Навигатор.


Примечание: работе скрипта не мешают гуляние по окнам (настройки терминала, свойства графика, архив котировок и т.д.) и присутствие нескольких запущенных терминалов.

That was very help ful. Do you know if it is possible to login to an account using Account number and password instead of picking them from favourite. Thanks.

 

i think it should be possible.

add one account to favorites

and instead of pressing just "enter" in login form

     hwnd = GetLastActivePopup(hwnd_parent);  // found login form
     PostMessageA(hwnd, WM_KEYDOWN, VK_ENTER, 0); // "enter" to login

you should send keystrokes of account number, then "Tab" key to move to password field, send keys for password and finally send "enter"

 

I compiled the code below, but I get error message:


2;89;C:\Program Files\MIG Trading Station\experts\reconnector login.mq4;42:5;'\end_of_program' - unbalanced left parenthesis


Someone can help me to fix?

thanks.

int min1 = 62;

#import "user32.dll"

{

min1 = TimeMinute(TimeCurrent();
Sleep(70000);
if (TimeMinute (TimeCurrent() == min1) counter = counter + 1;
else counter = 0;
if (counter > 5) {
hwnd = GetDlgItem(hwnd_parent, 0xE81C); // ????? ????????? ???? ?????????
hwnd = GetDlgItem(hwnd, 0x52);
hwnd = GetDlgItem(hwnd, 0x8A70);

PostMessageA(hwnd, WM_KEYDOWN, VK_ENTER, 0); // "enter" to login
Sleep(1000);
}
counter = 0;
return;
}

 

Change:

min1 = TimeMinute(TimeCurrent();

to

min1 = TimeMinute(TimeCurrent());


and

if (TimeMinute (TimeCurrent() == min1) counter = counter + 1;

to

if (TimeMinute (TimeCurrent()) == min1) counter = counter + 1;

Also, 'counter = counter + 1;' is like the longest way you can write what you want to happen here.

count += 1; //will add 1 to current value.. advantage to this is you can add any number.

count++; //increments the current value by 1.. advantage of this is that you can actually increment while using the variable to save a line of code in a loop or something.

I want to do something similar. The problem as I see it is that as one can only attach one EA at a time to a chart is that having this EA on it rules out the ones that I want to utilize to handle the trading functions. It seems to me that a valid way around this is to have a 'dummy chart' in each account that doesn't do any trading but hosts the rotating LogIn EA. I think that this will do the trick? Am I one the right track with this method or am I just going down the garden path and will only end up lost in the woods?

Perchance does anyone happen to have this with the documentation in English?

Thanks to one and all.

It's not really answering your question, but personally I'd say that this sort of kludge to log in to different accounts by simulating keystrokes is suicidally dangerous. I wouldn't be able to sleep at night I were trading live money using something like this. If one login goes wrong, the entire system potentially stops working - because it gets no further ticks.

It won't be simple, but a much better answer is to have multiple copies of MT4, each logged in to a separate account, and broadcast messages between them.
