Triangular arbitrage

Sunday, February 7th, 2010

Triangular arbitrage (sometimes called triangle arbitrage) refers to taking advantage of a state of imbalance between three foreign exchange markets: a combination of matching deals are struck that exploit the imbalance, the profit being the difference between the market prices.

Triangular arbitrage offers a risk-free profit (in theory), so opportunities for triangular arbitrage usually disappear quickly, as many people are looking for them, or simply never occur as everybody knows the pricing relation.

Example

Consider the three foreign exchange rates among the Canadian dollar, the U.S. dollar, and the Australian dollar. Triangular arbitrage will produce a profit whenever the following relation does not hold:

CD$/US$ * AU$/CD$ = AU$/US$.

For example if you can trade at these exchange rates

* the Canadian Dollar (CD$) against the US dollar (US$) is CD$1.13/US$1.00 (1 US$ gets you CD$1.13)
* the Australian Dollar (AU$) against the US dollar (US$) is AU$1.33/US$1.00 (1 US$ gets you AU$1.33)
* the Australian Dollar (AU$) against the Canadian Dollar (CD$) is AU$1.18/CD$1.00 (1 CD$ gets you AU$1.18)

1.13 * 1.18 = 1.3334 > 1.3300, thus mispricing has occurred.

To take advantage of the mispricing, starting with US$10,000 to invest:

* 1st buy Canadian Dollars with his US Dollars: US$10,000 * (CD$1.13/US$1) = CD$11,300
* 2nd buy Australian Dollars with his Canadian Dollars: CD$11,300 * (AU$1.18/CD$1.00) = AU$13,334
* 3rd buy US Dollars with his Australian Dollars: AU$13,334 / (AU$1.33/US$1.0000) = US$10,025
* Net risk free profit: US$25.00

A profit maximizing trader presented with these prices will trade up to the maximum size possible, or equivalently do the trade as many times as possible, until one of the traders on the other side of one of the deals changes his price. In practice currencies are quoted with a bid ask spread, so a trader should be careful that he is actually buying at the quoted ask price, and selling at the quoted bid price. Other transaction costs, such as commissions often prevent the trade from being profitable.

Oanda Corporation

Friday, February 5th, 2010

OANDA Corporation is a financial services provider of currency conversion, online retail foreign exchange (forex) trading, online foreign currency transfers, and forex information. It is one of the largest non-bank Futures Commission Merchants (FCMs) that specializes solely in spot forex trading. OANDA is a registered FCM with the Commodity Futures Trading Commission (CFTC) and a member of the National Futures Association (NFA).

The name OANDA is short for “Olsen And Associates” named after the founder.

OANDA.com offers an online trading platform (FXTrade), currency conversion tools, a foreign exchange wire service (FXGlobalTransfer), a corporate hedging consulting service (FXConsulting), discussion forums, tables of historical currency data, as well as forex news and analysis OANDA’s historical tables are used by some companies to calculate average exchange rates for accounting purposes. Since these historical rates remain accessible afterwards, they can also be used to define applicable exchange rates for contracts. OANDA provides many Foreign Exchange services besides FXTrade, their FOREX trading platform. They provide conversion tools and currency charts for businesses to integrate into their sites and indexes and information for travelers.

Unique Features

OANDA’s founders published The Forex Trader’s Bill of Rights to highlight what they describe as the fundamental right of foreign exchange traders to a free, open, and stable forex market, including technological efficiency and unfettered access to information.

One feature included in this Bill of Rights is the application of continuous interest, second-by-second, a feature of OANDA’s FXTrade platform. When interest is applied only once a day on open positions (the typical broker’s standard), there is an artificial bias toward shorting weaker currencies (with higher rates of interest), and, potentially, rewarding buyers of stronger currencies with lower rates of interest. The “Bill of Rights” asserts that this practice results in “distorted pricing flows that upset trends, create valuation havoc, and encourage speculation for its own sake.”

Mathematician BenoĆ®t Mandelbrot singles out OANDA’s FXTrade technology as one example of how the foreign exchange market should work to ensure liquidity. The forex market, despite its vast size, can be vulnerable to periods of illiquidity. These periods pose a risk to an interconnected globalized economy that is increasingly dependent on foreign currency exchange for currency disintermediation and micro-hedging, along with everyday B2B and B2C cross-border transactions.

History

OANDA is an outgrowth of the Swiss Olsen Group and was created to serve as an internet trading platform to automate techniques based on the group’s 20 years’ worth of research in foreign exchange trading. Much of OANDA’s technology is based on algorithms published in the book High Frequency Finance, which was co-authored by Dr. Richard Olsen, a principal of OANDA and co-inventor of these algorithms.

OANDA Corporation was incorporated in 1996 in the state of Delaware, and initially provided online access to live currency information that was previously inaccessible to the public at large. At its inception, OANDA.com offered free currency conversion tools, tables of historical data, news, and analysis through a multilingual interface, and other information likely to be of use to international travelers.

In 2001, OANDA launched FXTrade, an online forex trading system designed with the aim to lower the costs and risks associated with forex trading. Some of its more innovative features included flexible trade sizes, 24/7 trading, instant settlement on all transactions, continuous interest payments calculated second-by-second throughout the day, and no lot size restrictions (that is, traders could buy and sell any number of units, all at the same rate).

In 2005, OANDA published The Forex Trader’s Bill of Rights to outline its philosophy of what forex markets can and should offer to forex traders. In 2007, OANDA offered spot trading in an expanded list of currencies, including the Chinese yuan.

In 2008 OANDA launched FXGlobalTransfer, an automated online foreign currency transfer service designed to offer corporate clients a low-cost, convenient, and secure method of sending funds globally at any time from any computer connected to the Internet. The same year, OANDA launched FXPedia, an online wiki of forex information and commentary, and FXConsulting, a consulting service for corporate hedging.
