Thank you,

From the sources on your list fxclub is obviously the most precise. It also closely cross references with the reliable oanda's fx market hours. Ivestopedia is vague (at a continent level) and babypips is a cartoon.

FX market session hours are not exact.

Different exchanges/banks/institutions within the same region (even city?) may operate on slightly different hours, which explains the minor discrepancies among this list of sources, depending on which approximation for fx market hours each source uses.

My preferred method for selecting practical fx trading hours is to use intraday volatility tendencies of individual currency or currencypair (aka see the very clear repeating pattern every day after day in mt4 "volume").

Enjoy the further complication

The times I have for markets: seems to work well. All times GMT.

Sydney................ open 22.00 - 6.00
Tokyo..................open 23.00 - 7.00 ( 3 markets open 00.00 - 6.00 )
Hong kong............ open 00.00 - 8.00
Frankfurt............. open 7.00 - 15.00 (2 markets open 7.00 - 8.00 )
London................open 8.00 - 16.00 ( 2 markets open 8.00 - 13.00) *
N Y ....................open 13.00 - 21.00 ( 3 markets open 13.00 -15.00) *

Adjust for DST

The trading relay baton is handed over from Japan to Europe at 7.00, great time for trades as is the overlap between London & NY.
* These times majority of the trading volume.
