Check Internet Connection Status with EA

Hi all,

I'm hoping someone will be able to help me with this EA i have coded. The EA uses the IsConnected() function to check the MT4 terminal's connection with the broker's server. It runs on an infinite loop checking the status every second. The problem is, it currently doesn't discriminate between the broker dropping the connection, or my ISP dropping the connection. So i'm wondering is there a way to somehow test my internet connect if IsConnected() returns False, but from looking through the MQL4 documentation it seems this is beyond the scope of MQL4. I was given some suggestions of something along the lines of pinging another broker's server, or loading google. This is easy to do manually obviously, but i would like to code it into the EA so it was automated, and also for the EA to then be able to determine whether it was the broker's connection of my ISP's connection.

Any ideas?

Thanks

you could see if you can connect to google or somewhere using winsock. i don't expect it to be a simple thing to do correctly, and i imagine some mildly creative uses of mql arrays since there are no such thing as structs in mql.

You could use wininet.dll:

#import "wininet.dll"
InternetOpen();
InternetCheckConnection();
InternetCloseHandle();

Thanks a lot for all that info Xaphod! I'll look into all that now

This indicator definetly checks for the BROKER connection.

No, it just uses the "IsConnected()" function, which doesn't discriminate between the broker dropping the connection or my ISP dropping the connection, thanks anyway though

hi rooicol,

would you mind sharing if/how you solved this in the end.

Cheers

PS: I just looked through most of your threads: excellent ideas/code you posted

Hi rooi,
would you be please so kind and contact me regarding the "Trade-Management-EA " you have coded for me last year.
I think there could be a bug or I have problems to understand some feature in the EA.
I cannot contact you via mail because everytime I try it I get a mail-error. Don't know why.
Thanks again for everything.
