High-Frequency Trading (HFT) has arbitrage at its core and it allows traders to take advantage of the difference in price of different markets or instruments. Price effectiveness in practical arbitration needs fast switching and high precision with the ability to handle a great deal of information at the same time. HFT firms manage to seize opportunities in the financial market through the use of algorithms noticing deficiencies or lapses and using them to make profits.
This article offers performance measures against all types of arbitrage strategies in high-frequency trading along with the challenges that were faced while implementing them.
What is Arbitrage in HFT?
Arbitrage is defined as the process of creating a profit by buying and then selling the same or closely related financial securities that are priced differently in separate markets or different forms. However, in quantitative trading, arbitrage does exist but in quarters of a second and requires efficient processes to be executed.
Key Features
Low Risk: Usually, the risk is low since the deals are made in nearly the same time place or both.
High Frequency: Because inefficiencies in the market happen often, there are numerous chances which is why HFT is perfect for arbitrage.
Dependency on Technology: Without proper technology, lagging networks, and efficient algorithms, dominance in this sector is impossible.
Types of Arbitrage in HFT
- Spatial Arbitrage
Concept: The practice of taking advantage of the differing prices for the same underlying asset on different theaters.
Example: A stock that is traded on the New York stock exchange as well as on NASDAQ is likely to trade at slightly different prices due because of disparity in demand and supply for them.
Strategy: One buys on the exchange with a lower price and at the same time sells on the exchange with the higher price.
- Statistical Arbitrage
Concept: Is a systematic arms-length approach where models are used to look for price relationships on two or more assets’ prices that have been correlated and aims at arbitraging when such relationships have deviated.
Example: For instance when the price of S and P 500 or other equity indices moves upwards as in bull markets or regions, share prices move sensitive to each other when two companies are up in pricing highly correlated, if prices of the two such stocks diverge significantly or if the price of one of them sinks the model will predict a price reversal and trade as such.
Strategy: A common strategy is Pair trading which is in offset. Where a trader by going long does buy the lost stoked and short the stronger moving stock.
- Triangular Arbitrage
Concept: The lack of proper currency exchange practices or pricing marketing, efficiency in currency pricing on the forex market.
Example: For example when prices of USD/EUR, EUR/GBP, and GBP/USD are not consistent during a period, it is possible for a trader to fish in these prices by circulating these currencies and make profit.
Strategy: Make quick trade and finish the currency loop before prices set up!
- Index Arbitrage
Concept: Improper pricing of an index and at the same time its more than one part.
Example: Traders sell S&P 500 Index when it is higher than weighted value of its traded stocks and stock values in the portfolio is lower than it.
Merger Arbitrage, also simply referred to as risk arbitrage, constitutes the fifth concept that traders often employ in a search for profits. Risk arbitrage can be defined as pursuing profits arising out of the difference in the prices that the two firms offer during a merger or an acquisition.
Let’s say one firm makes a public tender offer to purchase a controlling interest in another firm. Given the nature of such announcements or public tender offers, the shares of the target firm are likely to be hovering around the pre-offer price, but to the trader’s advantage, selling pressure may not exist. Here traders purchase the shares by hedging off the risk with derivatives.
Inter-merchant arbitrage is also a strategy employed by traders to take advantage of the difference in the two quoting prices in two distinct platforms. Using co-location, a determining factor that causes latency arbitrage will be lowered as well. Latency arbitrage predominantly entails end users exploiting time delays that exist in the dissemination of information across different exchanges.
Through co location, a primary benefit to a trader is the fast execution of an order. With the marriage between co-location and order book analysis, traders are able to monitor the trading history of an exchange and track when the two quoting prices deviate.
Additional profit opportunities by utilizing order book analysis include better understanding of the structure of a micro market, resulting in better overall trade execution. As the micro market is heavily influenced from the top down, implementing machine learning models can effectively predict relative arbitrage opportunities in the future.
Some platforms also pitch a narrow range of selecting a quote without significant or rapid moves in the price leading to lower transaction costs which in turn creates expansionary profit opportunities. Thus, execution algorithms are of significant assistance to a trader.
