Backtesting high-frequency strategies with strict trading rules and settings is difficult. Not only is it difficult to backtest, but you would also be less likely to replicate the results in live trading. Thus, we soo no point in spending a lot of time on such a backtest.

Broker-dealers now compete on routing order flow directly, in the fastest and most efficient manner, to the line handler where it undergoes a strict set of risk filters before hitting the execution venue(s). Since the introduction of automated and algorithmic trading, recurring periods of high volatility and extreme stock price behaviour have plagued the markets. Johnson et al. (2013) define these so called price spikes as an occurrence of a stock price ticking down [up] at least ten times before ticking up [down] and with a price change exceeding 0.8% of the initial price.

Similarly, Oesch (2014) describes an ABM that highlights the importance of the long memory of order flow and the selective liquidity behaviour of agents in replicating the concave price impact function of order sizes. Although the model is able to replicate the existence of temporary and permanent price impact, its use as an environment for developing and testing trade execution strategies is limited. In its current form, fxcm canada review the model lacks agents whose strategic behaviours depend on other market participants. Since its introduction, recurring periods of high volatility and extreme stock price behaviour have plagued the markets. The SEC and CFTC (2010) report, among others, has linked such periods to trading algorithms, and their frequent occurrence has undermined investors confidence in the current market structure and regulation.

Unfortunately, Smith et al. (2003) notes that approaches such as this fail to appreciate the function of the LOB to store liquidity for future consumption. More recently, ABMs have begun to closely mimic true order books and successfully reproduce a number of the statistical features described in Sect. In the empirical research studies outlined above, the values of the Hurst exponent varied from \(H \approx 0.58\) on the Shenzhen Stock Exchange to \(H \approx 0.815\) for the USD/JPY currency pair.

Understanding High-Frequency Trading

Fractions of a cent added up from millions of trades turn into quite a large chunk of money. Financial economics models tend to be built upon the idea of liquidity being consumed during a trade and then replenished as liquidity providers try to benefit. Foucault et al. (2005) and Goettler et al. (2005), for example, describe theoretical models of LOB markets with finite levels of resilience in equilibrium that depend mainly on the characteristics of the market participants.

Is Algorithmic Trading Legal?

In 1987, high-frequency trading was linked to the “Black Monday” stock market crash that erased 22.6% from the Dow Jones Industrial Average, the biggest one-day percentage loss in history. As is often the case with market crashes, no single factor was responsible for the downturn. But almost all researchers acknowledge that algorithmic trading played a key role in the epic sell-off.

That said, algorithms and algorithm-based trading systems are not perfect. With so much volatility, the sheer speed of HFT systems can sometimes spark major selloffs in mere seconds. This method typically troubles big movers and is frequently at play in places known as “dark pools.” These are either private exchanges or forums that don’t report their order book in real time. Regulations typically require transaction information to be released, but it’s perfectly possible to delay it for long enough for big institutional users to perform large trades without immediately impacting the market.

Cumberland Mining, a subsidiary of Chicago-based firm DRW is the biggest. Even so, there are very few cryptocurrency exchanges that can currently offer eitherthe tools or the speed required for HFT. Some think it gives an unfair advantage, while others think it adds stability and liquidity to the crypto market.

It runs counter to the initial vision for cryptocurrencies—that of reimagining money and removing it from the control of the elite, but once again, the elite have found a way to reassert their influence.

Such environment not only fulfills a requirement of MiFID II, more than that, it makes an important step towards increased transparency and improved resilience of the complex socio-technical system that is our brave new marketplace. Figure 9 shows the relative number of crash and spike events as a function of their duration for different schemes of high frequency activity. The solid line shows the result with the standard parameter setting from Table 2. The dashed line shows results from a scheme with an increased probability of both types of high frequency trader acting. Here, we see that there is an increased incidence of short duration flash events. It seems that the increased activity of the trend follows causes price jumps to be more common while the increased activity of the mean reverts ensures that the jump is short lived.
