This re-balancing creates unique opportunities for algo traders who exploit the expected trades that are due to take place before the re-balancing of the fund. This type of strategy is the domain of algorithmic traders as trades are taken within nano-seconds to get the best prices.

Most retail trading platforms won't support this type of trading strategy either and is mostly geared for quantitative trading hedge funds who specialise in such high-frequency types of trades. Arbitrage refers to the practice of finding opportunity in the price difference between two or more markets. This can happen when the same market is traded across different exchanges.
For example, the price of Bitcoin can often differ between the various cryptocurrency exchanges. While the concept is quite simple, in practice, only algorithmic trading robots can take advantage of these price differences as they may only happen for a few seconds or less. Therefore, this type of strategy is mainly designed for high-frequency traders with access to the best speeds and execution models.
Most institutional traders utilising high-frequency arbitrage trading strategies will have internet cables connecting directly to these exchanges to take trades within nano-seconds. Mean reversion is the effect of a market's price trading back to its historical average price. This type of strategy is usually based on a mathematical model that assumes an asset's high or low price is temporary and will move back to its average price over a period of time. Technical trading indicators such as moving averages and Bollinger bands are widely used in mean reversion trading strategies. This is due to the fact a moving average provides the average historical price of an asset, while the Bollinger bands help to identify a market that has moved too far away from an average, using standard deviation as a measure of its volatility.
Below is an example chart taken from the MetaTrader 4 trading platform provided by Admiral Markets showing two technical trading indicators: the period exponential moving average shown by the purple line and Bollinger bands 20,2, shown by the green lines. There are certain occasions, or market conditions, where price often trades between the upper and lower Bollinger bands, reverting back to the middle of the bands which is most commonly the period moving average.
In the right market conditions, traders will often use volatility indicators like this for mean reversion trading strategies.

Past performance is not an indication of future performance. This type of trading strategy can be more suited to retail traders who trade on a higher timeframe such as the daily, four-hour and one-hour chart. The indicators can be found on most trading platforms and are already used by most traders manually. Of course, the specialisation comes in when trying to code and program the strategy. However, traders don't need to learn how to code to take advantage of algo trading strategies as you will learn further down this article.
A relatively new form of algorithmic trading is the use of machine learning and artificial intelligence AI. Most algo strategies are only as good as the predetermined inputs in the programming language created by the trader and programmer. With machine learning AI trading strategies, the trading robot updates itself on what has and has not been working. After nearly bankrupting his firm through a wrongly predicted trading idea, Dalio re-evaluated his methods and moved to a systemised method called the Pure Alpha fund strategy. It is mostly algo based and has been one of the main contributors to Dalio's success.
The hedge fund is now trying to develop this strategy into an artificially intelligent program, moving towards a more algorithmic-based approach. It is a groundbreaking area that will be out of reach for most retail traders and even most investment banks at such an early stage in its development.

The idea is that if a trend is in place then the market could continue in that direction until there are signals it has come to end.
This is actually one reason why movements in the financial markets have changed considerably over time. Nowadays price moves tend to go much further and faster due to a lot of algorithms jumping on board the move very quickly. Many retail traders would employ the use of technical trading indicators such as moving averages to help identify the long-term trend, as well as indicators to help identify overbought or oversold conditions. Instead of being there themselves to analyse the right time where all these conditions line up, they may code their strategy into an algo trading system which will then automatically search for these conditions and place trades according to user-defined parameters - saving a huge amount of time.
For example, below is a chart taken from the MetaTrader 4 trading platform provided by Admiral Markets with a blue period moving average line, a red period moving average line and a Stochastic Oscillator 5,3,3 indicator window at the bottom. Manual traders will often look to initiate long positions when the faster-period moving average such as the period is higher than the slower-period moving average such as the period and also look for short positions when the faster-period moving is lower than the slower-period moving average.
A screenshot of the MetaTrader 4 trading platform provided by Admiral Markets showing the period and period exponential moving average and the Stochastic Oscillator 5,3,3 window. Oscillators such as the Stochastic are often used as signs of overbought or oversold conditions.
Manual traders would look to initiate long positions when the moving averages indicate an uptrend with price at an oversold level, as well as short positions when the moving averages indicate a downtrend with price at an overbought level. Algorithmic traders would look to code these conditions into an automated trading system, allowing the algo to take trades automatically when the pre-programmed conditions have been met, thereby saving time for the trader.
The above list represents some of the most common types of algorithmic trading strategies. Unfortunately, many of them will be difficult to implement for most retail traders with zero or limited knowledge in a programming language. A traditional trading system consists primarily of two blocks — one that receives the market data while the other that sends the order request to the exchange. However, an algorithmic trading system can be broken down into three parts:. Exchange s provide data to the system, which typically consists of the latest order book, traded volumes, and last traded price LTP of scrip.
The server in turn receives the data simultaneously acting as a store for historical database. The data is analyzed at the application side, where trading strategies are fed from the user and can be viewed on the GUI. Once the order is generated, it is sent to the order management system OMS , which in turn transmits it to the exchange. Gradually, old-school, high latency architecture of algorithmic systems is being replaced by newer, state-of-the-art, high infrastructure, low-latency networks.

The complex event processing engine CEP , which is the heart of decision making in algo-based trading systems, is used for order routing and risk management. With the emergence of the FIX Financial Information Exchange protocol, the connection to different destinations has become easier and the go-to market time has reduced, when it comes to connecting with a new destination. With the standard protocol in place, integration of third-party vendors for data feeds is not cumbersome anymore.
Automated trading must be operated under automated controls, since manual interventions are too slow or late for real-time trading in the scale of micro- or milli-seconds. A trading desk or firm therefore must develop proper automated control frameworks to address all possible risk types, ranging from principal capital risks, fat-finger errors, counter-party credit risks, market-disruptive trading strategies such as spoofing or layering, to client-hurting unfair internalization or excessive usage of toxic dark pools.
Market regulators such as the Bank of England and the European Securities and Markets Authority have published supervisory guidance specifically on the risk controls of algorithmic trading activities, e. In response, there also have been increasing academic or industrial activities devoted to the control side of algorithmic trading. One of the more ironic findings of academic research on algorithmic trading might be that individual trader introduce algorithms to make communication more simple and predictable, while markets end up more complex and more uncertain.
However, on the macro-level, it has been shown that the overall emergent process becomes both more complex and less predictable.
How to Develop Algorithmic Trading Strategies in 2021
Though its development may have been prompted by decreasing trade sizes caused by decimalization, algorithmic trading has reduced trade sizes further. Jobs once done by human traders are being switched to computers. The speeds of computer connections, measured in milliseconds and even microseconds , have become very important. Economies of scale in electronic trading have contributed to lowering commissions and trade processing fees, and contributed to international mergers and consolidation of financial exchanges.
Competition is developing among exchanges for the fastest processing times for completing trades. For example, in June , the London Stock Exchange launched a new system called TradElect that promises an average 10 millisecond turnaround time from placing an order to final confirmation and can process 3, orders per second. This is of great importance to high-frequency traders, because they have to attempt to pinpoint the consistent and probable performance ranges of given financial instruments.
With high volatility in these markets, this becomes a complex and potentially nerve-wracking endeavor, where a small mistake can lead to a large loss. Absolute frequency data play into the development of the trader's pre-programmed instructions.

In the U. Algorithmic trading has caused a shift in the types of employees working in the financial industry. For example, many physicists have entered the financial industry as quantitative analysts. Some physicists have even begun to do research in economics as part of doctoral research. This interdisciplinary movement is sometimes called econophysics. Algorithmic trading has encouraged an increased focus on data and had decreased emphasis on sell-side research.
Algorithmic trades require communicating considerably more parameters than traditional market and limit orders. A trader on one end the " buy side " must enable their trading system often called an " order management system " or " execution management system " to understand a constantly proliferating flow of new algorithmic order types.
What was needed was a way that marketers the " sell side " could express algo orders electronically such that buy-side traders could just drop the new order types into their system and be ready to trade them without constant coding custom new order entry screens each time. FIX Protocol is a trade association that publishes free, open standards in the securities trading area.
How does auto trading work?
The FIX language was originally created by Fidelity Investments, and the association Members include virtually all large and many midsized and smaller broker dealers, money center banks, institutional investors, mutual funds, etc. This institution dominates standard setting in the pretrade and trade areas of security transactions. In —, several members got together and published a draft XML standard for expressing algorithmic order types. From Wikipedia, the free encyclopedia.
