Pros and Cons of High Frequency Forex Trading


Computers are used to make decisions. Since high-frequency trading is carried out by sophisticated algorithms and powerful computers, no judgments made by these techniques will ever be influenced by human emotion or psychology.

Not everyone should use HFT. The creation and upkeep of an HFT strategy demand a high level of technical expertise.

Is trading forex at high frequency legal?

High-frequency trading is, in fact, lawful. Having said that, it’s conceivable that your broker will forbid high-frequency trading techniques. Some brokers outright forbid price- or latency-driven arbitrage methods (such as scalping). To find out whether your HFT technique will be approved, speak with your broker directly. It’s also a good idea to thoroughly review your broker’s terms and conditions.

It’s crucial to be aware of the exact types of trading circumstances that are offered if your broker does allow HFT tactics or systems, as well as to pay attention to your broker’s execution procedures and trading fees. High-frequency trading could not even be possible if your broker makes it too expensive, even if they do allow it.

Despite being legal, HFT systems are nonetheless divisive. Spoofing and front-running are two well-known HFT techniques that are categorically prohibited.

When a high-frequency trading system quickly sets a large number of orders, it engages in spoofing when it cancels those orders before they can be carried out. This tactic is used with the intention of feigning demand for a certain asset or instrument (or artificially pushing demand down).

Front-running: HFT traders (or institutions) may occasionally be able to see big orders that are about to be placed in the market for a particular asset or instrument, even before the orders are actually filled. With the help of confidential information, this is (usually) done unlawfully. Then, these institutions or traders may swiftly purchase substantial amounts of that asset using HFT systems, which they can later sell for a profit.

Despite all of this, laws and regulations have been implemented during the past 20 years or more to protect market participants, discourage actions like front-running, and generally safeguard market integrity. To level the playing field, several stock exchanges, for instance, have enacted a general speed bump that slows down all incoming orders. These days, many forex market brokers and trading platforms completely forbid HFT methods that are latency-driven or that just seek to take advantage of price arbitrage.
