Cryptocurrency Triangular Arbitrage

Profitable triangular arbitrage is very rarely possible because when such opportunities arise, traders execute trades that take advantage of the imperfections and prices adjust up or down until the opportunity disappears. The FX market is characterized by singular institutional features, such as the absence of a central exchange, exceptionally large traded volumes and a declining, what is triangular arbitrage yet significant dealer-centric nature . Electronic trading has rapidly emerged as a key channel through which investors can access liquidity in the FX market . For instance, more than 70% of the volume in the FX Spot market is exchanged electronically . A peculiar stylized fact of the FX market is the significant correlation among movements of different currency prices.

A triangular arbitrage opportunity occurs when the exchange rate of a currency does not match the cross-exchange rate. The price discrepancies generally arise from situations when one market is overvalued while another is undervalued. This type of arbitrage is a riskless profit that occurs when a quoted exchange rate does not equal the market’s cross-exchange rate. International banks, who what is triangular arbitrage make markets in currencies, exploit an inefficiency in the market where one market is overvalued and another is undervalued. Price differences between exchange rates are only fractions of a cent, and in order for this form of arbitrage to be profitable, a trader must trade a large amount of capital. The significant probabilities of returning to stem from the interplay of two elements.

Cross Exchange Rate Discrepancies

Hence, the exchange rate may be overvalued in one market and undervalued in another. In this regard, foreign exchange market participants, such as international banks, exploit such inefficiencies to profit. The model introduced in the present study could be subject of meaningful extensions and enhancements aimed to turn this framework into a valuable tool that could be used by exchanges, regulators and market designers. Furthermore, its applicability might attract the attention of other actors operating in the FX market, such as central banks. Triangular arbitrage opportunities may only exist when a bank’s quoted exchange rate is not equal to the market’s implicit cross exchange rate.

In our example, when traders buy pesos with dollars, they drive up the price of the peso in the dollar-peso market. When they buy pounds with pesos, they drive up the price of the pound in the pound-peso market. Finally, when they buy dollars with pounds to make their profit, they drive down the price of the pound in the dollar-pound market.

European terms is a foreign exchange quotation convention where the quantity of a specific currency is quoted per one U.S. dollar. We will discuss the law of one price and examine examples of arbitrage opportunities. The limit order with the best price (i.e., the highest bid or the lowest ask quote) is always the first to be matched against a forthcoming order. The adoption of a minimum price increment δ forces the price to move in a discrete grid, hence the same price can be occupied by multiple limit orders at the same time. As a result, exchanges adopt an additional rule to prioritize the execution of orders bearing the same price. A very common scheme is the price-time priority rule which uses the submission time to set the priority among limit orders occupying the same price level, i.e., the order that entered the LOB earlier is executed first .

However, this study fails to explain whether and how reactions to triangular arbitrage opportunities lead to the characteristic shape of the time-scale vs. cross-correlation diagrams observed in real trading data . The Arbitrager Model restricts its focus to the interactions between two types of strategies, namely triangular arbitrage and trend-following. Despite the simplicity of this framework, the interplay between these two strategies alone satisfactorily reproduces the cross-correlation functions observed in real trading data. The interactions between these two strategies constantly push the system towards certain configurations and away from others through multiple mechanisms. This can be easily seen in Fig 7 as two distinct statistics, the average expected lifetimes and the appearance probability, put the eight configurations in the same order. For instance has the longer expected lifetime but also the highest appearance probability.

Finally, echoing , the ecology hosts a special agent (i.e., the arbitrager) that is allowed to submit market orders in any market to exploit triangular arbitrage opportunities, see Fig 4. Second, certain ecology configurations are expected to last more than others (i.e., single episodes). As reactions to triangular Complementary currency arbitrage opportunities increase the likelihood of flipping a market state, the average lifetime of a given configuration relate to the time required for the first triangular arbitrage opportunity to emerge. This difference can be intuitively explained by looking at the combination of market states.

This force shapes the features of the statistical relationships between currency pairs. FX rates traded in markets that share the same state in configurations with higher appearance probabilities and longer expected lifetimes are more likely to fluctuate in the same direction. These two markets have the same states in the four configurations with higher probabilities (i.e., , , and ) and opposite states in those with lower probabilities (i.e., , , and ). It follows that the probability of observing USD/JPY and EUR/JPY in the same state at a given point in time t is ≈ 60%, see Fig 6. In these settings, the mid price dynamics of two FX rates become permanently entangled, leading to the cross-correlation functions displayed in Figs 5 and 6.

For example, if a trader places each trade as a limit order to be filled only at the arbitrage price and a price moves due to market activity or new price is quoted by the third party, then the triangular transaction will not be completed. In such a case, the arbitrageur will face a cost to close out the position that is equal to the change in price that eliminated the arbitrage condition. The Arbitrager Model satisfactorily replicates the characteristic shape of ρi,j(ω), suggesting that triangular arbitrage plays a primary role in the entanglement of the dynamics of currency pairs in real FX markets. However, two quantitative differences between the model-based and data-based characteristic shape of ρi,j(ω) emerge in Fig 5.
