Not sure I can help but wondering what kind of server are you using currently that allows your to Open 32 platforms? Seems like a CPU limitation.
Are you getting an error message when you try to open the 33rd platform? Can you send the screenshot of the error?

We have to know the error message, look at the "journal" tab. 32 sounds like a system limit. Programmers typically chose numbers like 32 or 16 or 64 for such limits.

Perhaps the MQL4 website might be a more appropiate forum for this, or ask your broker.

The server is from two brokers, XM and GFC. Windows 7 don't make any error in 33th platform, it just doesn't open a new one, even if I try many times don't open a new one after the 32th platform, maybe is like you say, a limitation of windows or mt4...don't know.

I use Win7 x32, maybe have a limit of 32 apps opened at same time. What a bad luck... . Ok I will search in MQL4 forum. Thank you so much.

Where I can find that "journal" tab?

It's a MT4 limitation. It allows you to run at most 32 terminals per machine at a time.

If you want to run 40 terminals, you'll have to use two machines. Or find a way to avoid the max 32 terminal limitation.

Hello Invermac,
Just out of curiosity, I would like to ask you why would you need more than 40 open platforms at the same time? I just could not imagine the reason behind such action. Also, in my mind this could potentially cause server overload, or platform crashes.
Cheers,
Ulli

Hello UlliC
The reason is because I'm handling some clients accounts and have more than 20 clients but this month I will have new clients and I was looking for a new powerful computer, but with this limitation I will buy some basic PC to handle more accounts.
I'm handling right now 23 accounts and don't have any problem.

Hi Invermac,
Wouldn’t be easier to use some sort of MAM/PAMM tool? Most Brokers offer them to licensed MMs.

i can think of two ways:

1) TradeTools Multiterminal : access multiple accounts within 1 MT4
http://www.tradetoolsfx.com/index.ph...d-metatrader-5

2) Metaquotes VPS : it's not really a Windows that you can log in but rather resources that you can apply to accounts. i think the number of accounts is unlimited and it's cheap too.

Hi Invermac, I facing the same problems like you too. Do you find out any solutions to add more MT4 in the PC?

you might want to try a trader advisor account - trades all subaccounts simultaneously, with only one platform running on your computer
talk to your broker

I'm not an affiliate or a customer but I do know such a thing is possible with this software intended for tick data testing.

I also really appreciate the special class of people that take the time to post and share their success, but never include any DETAILS

WTF
It takes a lot for me to IGNORE you, but you can try.
