Contrary to stock markets and other markets, geography doesn’t play a role in the Forex market. Anyone can trade anywhere.
London, Tokyo and New York City are major financial hubs. True, during the afternoon in London, when it’s morning time in New York, trading volume is highest, but trading is available around the clock.
As long as you have an agency, you can trade. Most traders don’t even need a physical trading agency at their country. They open an account online, over the Internet, deposit money via credit card (or Paypal) and start trading with an agency that resides overseas.
Thus, the Forex market is totally globalized – it really doesn’t matter where you are. Well except for taxes on profits, something that is different from country to country.
