[B]Markets traded on exchanges[/B] open and close on a daily basis, mainly because they have done it that way since their founding, decades ago in most cases. In “the old days”, before electronic trading, these exchanges were local exchanges manned by people who worked a daytime shift and then went home. Later in their histories, many exchanges added “after-hours trading”, which sort of blurs the line between the market being open and being closed. But, that doesn’t apply to our market.
[B]The currency market is an off-exchange market,[/B] with no physical location, ultimately run by big banks that have offices in principal cities around the world, linked electronically. Most of these big banks, collectively known as the interbank network, have offices in Tokyo, London, and New York, where currency trading takes place. As the normal business day comes to an end in one location (Tokyo, say), each bank’s “book” of open positions and open orders is passed to the bank’s next trading desk (that would be London, in this example). The hand-off of the “book” is seamless, and customers of the bank are unaware of it. None of this was practical before the advent of computers and electronic communications networks, such as Reuters and EBS.
[B]This “top tier” of the currency market essentially never closes.[/B] You can be sure that if the Federal Reserve, or the Bank of England, wants to move big bucks at 2 am on a Sunday morning, they won’t have to wait for the currency market to open on Monday.
But, at the bottom of this market, where we trade — the retail spot forex market — we never deal with banks. We deal with retail forex brokers, who choose not to operate on the weekend, because they have found that there isn’t enough retail volume to make it worthwhile. [B]So, “the market”, as we experience it and have access to it, “closes” on Friday afternoon (New York time), and remains closed until Monday morning (New Zealand time), when a new retail trading week begins.[/B]
The broker Oanda experimented with 24/7 retail trading, staying open on the weekends, but abandoned the experiment, because it just wasn’t profitable.
