People who engage in arbitrage are called arbitrageurs (IPA: /ˌɑrbɨtrɑːˈʒɜr/)— such as a bank or brokerage firm. Te term is mainly applied to trading in financial instruments, such as bonds, stocks, derivatives,


commodities and

OF ARBITRAGE


• Arbitrage betting • Covered interest arbitrage • Fixed income arbitrage • Political arbitrage • Risk arbitrage • Statistical arbitrage • Triangular arbitrage • Uncovered interest arbitrage • Volatility arbitrage


FINANCIAL BROKER ARB


Broker arb is where a trader capitalizes on a price discrepancy between 2 brokers in the same market. For example Broker A offers a price of 1.4542 and Broker B offers a price of 1.4556. Broker arb is fair in that the broker is offering the price, but brokers who throw many bad prices may not like that traders are taking advantage of those bad prices.

• If the ‘slow broker’ is really slow, your profits could be large and he may not allow you to withdraw them


• There can be network or software upgrades that the strategy may work for a certain period of time and then stop working.


SOFTWARE ARB


Te least ethical, most dangerous, and most difficult to execute, is arb that takes advantage of discrepancies inside the soſtware trading platform. Tis was noticed in 2007 by some EA developers that had strategies that could effectively trade price discrepancies between MT4 server and MT4 terminal. In certain builds of MT4, MT4 would only update the terminal every X ticks (let’s use 10 as extreme example) – the
