The Impact of Algorithmic Trading on Foreign Exchange Markets

The forex market, the largest market in the global financial system, is currently facing a significant change in its trading landscape due to the increasing use of AT. Algorithmic traders commonly referred to as “algo traders” are traders that use computer generated programs to execute trades in the market, according to a set of rules and mathematical calculations. It means that the whole picture of how foreign exchange markets work has changed with the transition from human trading to algorithmic trading.

The current trend of speed and efficiency taken to the extreme

Perhaps, the most noticeable impact of AT is the lightning speed of executing operations in the forex market. The old conventional methods of forex trading were a manual system and were not efficient due to human factors and low response rates. Algo traders are on the other hand in a position to process large information in real-time, respond to market changes within a blink of an eye and perform trades in a similarly record time. This leads to the situation where the spreads are narrower, that is the difference between the buying and selling price is less, and possibly lower transaction costs for all members.

New Opportunities and Herding Phenomenon?

It also contributes to increasing market liquidity, as the following statement of AT shows: Algo traders can keep track of one or more of the pairs at the same time and instantly offer bids and offers for each, which makes the trading process less rigid. More liquidity may be advantageous to the small investor as well as institutions since position taking and exiting will be easier.

Though, a possible disadvantage associated with AT is that it may lead to herding behavior. This scenario causes many algo traders to make the same trades at the same time due to their reliance on the same data sources and similar techniques. This can exaggerate market movements and may cause flash crash or a period with high volatility in stock prices.

Volatility Tamed or Amplified?

Volatility is therefore another area where the effect of AT is still questioned. There are claims that algo traders improve the stability of the market because they are able to detect and exploit micro price discrepancies. With that in mind, they are able to constantly eliminate imbalances so that the price does not vary massively.

But critics argue that high frequency of an AT can even lead to an increase in volatility since it is traded more often. High-frequency transactions by the algo traders can increase the volatility in the markets because news and other economic factors will cause more significant movements in the short-term.

The Evolving Regulatory Landscape

This rise of AT in forex trading has not left the regulators out of sight and has been the subject of much scrutiny. The dilemma is, on one hand, to encourage competition, on the other – not to disrupt the market too much. Some of the possible regulatory steps that need to be taken are to introduce more severe limitations for short-term trading operations and to require disclosure of the algorithms used in algo trading.

What has a more Algorithmic Future for the Forex

Algorithmic trading is thus opening the future of the foreign exchange market. On one hand, it has a lot of advantages as for the speed, efficiency and availability but on the other hand such risks as herding and volatility should be taken into consideration. And with advances in technology, more efforts will be required from the regulators and the participants in the market to ensure that there is stability in the trading process and that there is transparency in the market.
