The result is consistent for a range of timescales s taken in our approach. It is interesting to note that this effect becomes more pronounced when longer timescales are implemented 24 h, 1 week. A similar conclusion is valid when considering GBP or JPY taken as the base currency—corresponding curves have a maximum in This could mean that the sudden overnight increase in the rates by the Bank of Canada in did not have longer lasting effect and was only causing very short term effect.

In order to identify promising arbitrage opportunities e. In view of the above findings where we have already identified an important role of the large fluctuations, a question arises to what extent even briefly occurring in time such extreme events fluctuations in currency exchange returns may influence the detrended cross-correlations. It is interesting to see how these extreme events manifest themselves as far as cross-correlations are concerned.

These exchange rates exhibit substantial volatility during considered years. The dashed line corresponds to the cross-correlation results with rejected periods of time with large volatility and existence of triangular arbitrage opportunities. The periods of extreme variation of exchange rates are shown in the corresponding insets of Fig. The insets show that in fact the exchange rates compared red and black curves were changing so rapidly that they could not follow each other.

In such a way, the possible arbitrage opportunities have arisen. Finally, let us investigate closely these brief in time periods of arbitrage opportunities we have identified by our data analysis. Color online Deviations from the triangular relations. In , existed a big arbitrage opportunity CHF , moderate arbitrage opportunity GBP in and no such opportunity in In this case, we use ask and bid prices for exchange rates instead of averaged ones in order to show this in more details.

All events indicated by values greater than 0 in fact could potentially offer triangular arbitrage opportunities. The top panel shows an example of potentially significant arbitrage opportunity which is related to the SNB intervention in and fluctuations in the CHF exchange rates. The middle panel of Fig.

Finally, the bottom panel illustrates rather weak chance of exploiting triangular arbitrage opportunity—there is only one very brief in time instance when in theory this might be possible. The arbitrage opportunities are very closely related to large fluctuations which tend to be more pronounced in the longer timescales s.

This is the case for exchange rates related to CHF and GBP, and this is precisely what opens windows of opportunities for the triangular arbitrage. We have investigated currency exchange rates cross-correlations within the basket of 8 major currencies.

Distributions of 10 s historical logarithmic exchange rate returns follow approximately the inverse cubic power-law behavior when the brief period of trading on January 15, , in the wake of the SNB intervention is excluded from the exchange rate data sets. The tails of the cumulative distributions of the high-frequency intra-day quotes exhibit non-Gaussian distribution of the rare events by means of the so-called fat tails large fluctuations.

This clearly documents that large fluctuations in the logarithmic rate returns occur more frequently than one may expect from the Gaussian distribution. We have found that on average the cross-correlations of exchange rates for currencies in the triangular relationship are stronger than cross-correlations between exchange rates for currencies outside the triangular relationship. Such dendrograms may have important applications related to hedging, risk optimization, and diversification of the currency portfolio in the Forex market. Such abrupt changes of cross-correlations combined with the presence of relatively large fluctuations may signal potential triangular arbitrage opportunities.

Finally, our conjecture is that during significant events e. Such events and the resultant opportunities indeed have been identified in the historical trading data for the period — The evidence we have shown clearly indicates that the multifractal cross-correlation methodology should contribute significantly to predictive modeling of temporal and multiscale patterns in time series analysis.

We believe that our present study, where we consider currencies interaction through their mutual exchange rates and the dynamics of the rates adjustment to a new conditions due to a sudden event, may encourage future research in studying the information propagation through complex networks of interacting entities. This in turn may have some consequences for design of new smart learning methods for neural networks and a general computational intelligence in predicting a future behavior of complex systems.

For example, since we have demonstrated feasibility of financial time series analysis against favorable patterns, we may expect future advancement in computer algorithms for financial engineering when trading tick-by-tick data are available in real time. Google Scholar.

Arbitrage, HFT, Quant and Other Automatic Trading Strategies in FX

Mantegna, R. B 11 , — E 95 , Banks use algos to trade between themselves and often sell them to clients for fees. Specifically in FX, we will dive into the following specialized strategies that are fairly common:. Using arbitrage in algorithmic trading means that the system hunts for price imbalances across different markets and attempts to profit from those. Arbitrage opportunities are usually short-lived, so you need to act fast.

START TRADING IN 10 MINUTES

Since the Forex price differences are in usually micropips a person would need to trade really large positions to make considerable profits. All of these price discrepancies might not last very long, because there are other traders out there watching prices and looking for the same opportunities, so you need to be quick. As the name suggests, this kind of trading system operates at lightning-fast speeds, executing buy or sell signals and closing trades in a matter of milliseconds.

These typically use arbitrage or scalping strategies based on quick price fluctuations and involve high trading volumes. High-frequency traders rely on extremely low latency and use high-speed connections in conjunction with trading algorithms to exploit inefficiencies created by these exchanges. At the time of writing, market contacts suggest that some HFT participants in FX can operate with latency of less than one millisecond, compared with 10—30 milliseconds for most upper-tier, non-HFT participants. In equities, this Internal processing time is one 64 millionth of a second.

Execution speed in FX is also far behind equities trading. As you can see, Nasdaq can execute orders in less than a millisecond, while the fastest margin FX broker is at 85 ms.
