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. Advanced Markets, for example, is an institutional broker and offers higher execution speed averaging at around 50ms with internal processing time of less than 3 milliseconds.
Market data delivered in ms packets will likely be unsuited for HFT strategy, so you need to find venues that can price faster for some its technical limitation. For example, Advanced Markets is expanding platform capability and can push updates into MT4 in a second. There are other limiting factors to HFT strategy like fill ratio, as the consequences of missing a large number of trades due to unfilled orders are likely to be catastrophic for any HFT strategy.

Scalping is another sub-type of HFT. It involves entering trades and closing them after a short time in order to make profits from small price changes. Scalpers profit from this movement. Quantitative trading is a type of market strategy that relies on mathematical and statistical models to identify — and often execute — opportunities.
The models are driven by quantitative analysis, which is where the strategy gets its name from. Quantitative trading works by using data-based models to determine the probability of a certain outcome happening.
The book alleged that the equities markets are rigged as a few small companies are using high- frequency trading to make a killing and dominate the markets. By jumping in front of investors through high-speed trades, traders are able to grab profits in the tens of billions.

US financial regulators are currently looking into whether firms using HFT have an unfair advantage over their competitors by using private information. However, some trading firms have defended the use of HFT methods, saying that high-frequency traders are simply exploiting glitches in the system.

Since high-speed trading provides transparency of prices, for instance, brokers can no longer provide preferential pricing to favored clients. The Futures Industry Association Principal Traders Group, which includes many of the biggest high-speed trading firms as members, said that HFT actually improves market quality which benefits all investors.
In addition, since high-speed trading can reduce spreads, defenders say it actually cuts the cost of trading, increasing the profits of currency traders. Meanwhile, other currency brokers are fighting back by using a trading platform called ParFX that was created to combat disruptive behaviour and create an environment where intelligence, rather than speed, was rewarded. The fight against HFT is fueled by declining profits in the currency markets.

High Frequency Trading HFT refers to the use of technology to automatically execute high volumes of transactions within very narrow time frames. In order to achieve the extreme speeds required for this type of trading, immense computing power is required, enabling positions to be opened and closed within microseconds.
What Is High-Frequency Trading?
The closer to exchanges that the HFT data centres are located, the less time it takes for the data to travel between the two. The complexity of these algorithms is continually increasing, refining their ability to make trading decisions based on pertinent information and enabling more accurate reactions to price and market changes. There are various different trading strategies that high frequency traders employ, many of which aim to benefit from price variations on similar assets. These include events arbitrage, exploiting price movements caused by financial and general events; statistical arbitrage, which uses complex mathematical modeling to compute and take advantage of pricing inefficiencies between assets; and latency arbitrage, which exploits price variations between different markets due to system delays, and the difference in price can be caused by HFT market manipulations.
High frequency traders also create liquidity within markets, acting as market makers. The market making strategy employed by HF traders takes advantage of differences between bid and ask spreads. Because of the automation, the tremendous speeds, and the sheer volume of trades they are capable of, high frequency traders are often able to take first-mover advantage in high impact news situations; including GDP and inflation data releases, nonfarm payrolls and monetary policy announcements.
Also, as the large scale trading is carried out by computers and not humans, HFT is not subject to error caused by the influence of human emotions. Conversely, computers may not react appropriately to shock or false events: the predefined algorithms may not be capable of adequately adapting towards such volatile market conditions, or distinguishing between genuine and false news events. Changes to algorithms are often made after experiencing significant losses. For example, a flash crash occurred in as large quantities of stock were sold by high frequency trading tools, resulting in many top stocks plummeting.
In these situations, the unnatural market activity high frequency trading can cause can, in turn, affect decisions made by unsuspecting traders. Critics of the practice also argue that the market liquidity that high frequency trading provides is limited, as it can become unavailable before other traders can take advantage of it. This is less of an issue within the forex market as there is already high liquidity — but equally, there are fewer liquidity benefits to be gained from high frequency trading within the forex market.
Finally, there is a limit to how much more competitive these sophisticated computing systems can become.
