MT4 daily open and close times

What are they for forex or how do I find them. The market watch is 2hrs ahead of GMT. Have a feeling its 2200 to 2200 GMT?
Thanks

With MT4 it's whatever the broker has set the time zone setting on their server to. UTC/GMT+2 is popular because the trading week then starts at midnight am on Monday (i.e. no Sunday data). Some brokers use UK time, some use UTC/GMT time and some use New York time. Take whichever choice you prefer.
