An algorithm is a specific set of clearly defined instructions aimed to carry out a task or process. Algorithmic trading automated trading, black-box trading, or simply algo-trading is the process of using computers programmed to follow a defined set of instructions for placing a trade in trading to generate profits at a speed and frequency that is impossible for a human trader. The defined sets of rules are based on timing, price, quantity or any mathematical model. Apart from profit opportunities for the trader, algo-trading makes markets more liquid and makes trading more systematic by ruling system emotional human impacts on trading activities. For more, check out Picking the Right Algorithmic Trading Software. Using this set of two simple instructions, it is easy to write a computer program which will automatically monitor the stock price and the moving average indicators and place the buy and sell orders when the defined conditions are met. The trader no longer needs to keep a watch for live prices and graphs, or put in the orders manually. The algorithmic trading system automatically does it for him, by correctly identifying the trading opportunity. For more on system averages, see Simple Moving Averages Make Trends Stand Out. The greatest portion of present day algo-trading is high frequency trading HFTwhich attempts to capitalize on placing a large number of orders at very fast speeds across multiple markets and multiple decision parameters, based on pre-programmed instructions. For more on high frequency trading, see Strategies and Secrets of High Frequency Trading HFT Firms. Algorithmic trading provides a more systematic approach to active trading than methods based on a human trader's intuition or instinct. Any strategy for algorithmic trading requires an identified opportunity which is profitable in terms of improved earnings or cost reduction. The following are common trading strategies used in algo-trading:. The most common algorithmic trading strategies follow trends in moving averageschannel breakoutsprice level movements and related technical indicators. These are the easiest and simplest strategies to implement through algorithmic trading because these strategies do not involve making any predictions or price forecasts. Trades are initiated based on the occurrence of desirable trendswhich are easy and straightforward to implement through algorithms without getting into the complexity of predictive analysis. The above mentioned example of 50 and day moving average is a popular trend following strategy. For more on trend trading strategies, see: Simple Strategies for Capitalizing on Trends. Buying a dual listed stock at a lower price in one trading and simultaneously selling it at a higher price in another market offers the price differential as risk-free profit or arbitrage. The same operation can be replicated for stocks versus futures instruments, as price differentials do exists from time to time. Implementing an algorithm to identify such price differentials and placing the orders allows profitable opportunities in efficient manner. Index funds have defined periods of rebalancing to system their holdings to par with their respective benchmark indices. This creates profitable opportunities for system traders, who capitalize on expected trades that offer basis points profits depending upon the number of stocks in the index fund, just prior to index fund rebalancing. Such trades are initiated via algorithmic trading systems for timely execution and best prices. A lot of proven mathematical models, like the delta-neutral trading strategy, which allow trading on combination of options and its underlying securitywhere trades are placed to offset positive and negative deltas so that the portfolio delta is maintained trading zero. Mean reversion strategy is based on the idea that the high and low prices of an asset are a temporary phenomenon that revert to their mean value periodically. Identifying and defining a price range and implementing algorithm based on that allows trades to be placed automatically when price of asset breaks in and out of its defined range. Volume weighted average price strategy breaks up a large order and releases dynamically determined smaller chunks of the order to the market using stock specific historical volume profiles. The aim is to execute the order close to the Volume Weighted Average Price VWAPthereby benefiting on average price. Time weighted average price strategy breaks up a large algo and releases dynamically determined smaller chunks of the order to the market using evenly divided time slots between a start and end time. The aim is to execute the order close to the average price between the start and end times, thereby minimizing market impact. Until the trade order is fully filled, this algorithm continues sending algo orders, according to the defined participation ratio and according to the volume traded in the markets. The related "steps strategy" sends orders at a user-defined trading of market volumes and increases or decreases this participation rate when the stock price reaches user-defined levels. The implementation shortfall strategy aims at minimizing the execution cost of an order by trading off the real-time market, thereby saving on the cost of the order and benefiting from the opportunity cost of delayed execution. The strategy will increase the targeted participation rate when the stock price moves favorably and decrease it when the stock price moves adversely. These "sniffing algorithms," used, for example, by a sell side market maker have the algo intelligence to identify the existence of any algorithms on the buy side of a large order. Such detection through algorithms will help the market maker identify large order opportunities and enable him to benefit by filling the orders at a higher price. This is sometimes identified as high-tech front-running. For more on high-frequency trading and fraudulent practices, see: If You Buy Stocks Online, You Are Involved in HFTs. Implementing the algorithm using a computer program is the last part, clubbed with backtesting. The challenge is to transform the identified strategy into an integrated computerized process that has access to a trading account for placing orders. The following are needed:. Here is a comprehensive example: Royal Dutch Shell RDS is listed on Amsterdam Stock Exchange AEX and London Stock Exchange LSE. Here are few interesting observations:. Can we explore the possibility of arbitrage trading on the Royal Dutch Shell stock listed on these two markets in two different currencies? However, the practice of algorithmic trading is not that simple to maintain and execute. Remember, if you can trading an algo-generated trade, so can the other market participants. Consequently, prices fluctuate in milli- and even microseconds. You will end up sitting with an open positionmaking your arbitrage strategy worthless. There are additional risks and challenges: The more complex an algorithm, the more stringent backtesting is needed before it is put into action. But one must make sure the system is thoroughly tested and required limits are set. Analytical traders should consider learning programming and building systems on their own, to be confident about implementing the right strategies in foolproof manner. Cautious use and thorough testing of algo-trading can create profitable opportunities. For more, see How to Code Your Own Algo Trading Robot. Dictionary Term Of The Day.

Basics of Algorithmic Trading: Concepts and Examples By Shobhit Seth Updated May 2, — 2: Suppose a trader follows these simple trade algo Buy 50 shares of a stock when its day moving average goes above the day moving average Sell shares of the stock when its day moving average goes below the day moving average Using this set of two simple instructions, it is easy to write a computer program which will automatically monitor the stock price and the moving average indicators and place the buy and sell orders when the defined conditions are met. Benefits of Algorithmic Trading Algo-trading provides the following benefits: Trades executed at the best possible prices Instant and accurate trade order placement thereby high chances of execution at desired levels Trades timed correctly and instantly, to system significant price changes Reduced transaction costs see the implementation shortfall example below Simultaneous automated checks on multiple market conditions Reduced risk of manual errors in placing the trades Backtest the algorithm, based on available historical and real time data Reduced possibility of mistakes by human traders based on emotional and psychological factors The greatest portion of present day algo-trading is high frequency trading HFTwhich attempts to capitalize on trading a large number of orders at very fast speeds across multiple markets and multiple decision parameters, based on pre-programmed instructions. Algo-trading is used in many forms of trading and investment activities, including: Mid to long term investors or buy side firms pension funds, mutual funds, insurance companies who purchase in stocks in large quantities but do not want to influence stocks prices with discrete, large-volume investments. Short term traders and sell side participants market makersspeculatorsand arbitrageurs benefit from automated trade execution; in addition, algo-trading aids in creating sufficient liquidity for sellers in the market.

The following are common trading strategies used in algo-trading: Mathematical Model Based Strategies: Trading Range Mean Reversion: Volume Weighted Average Price VWAP: Time Weighted Average Price TWAP: Percentage of Volume POV: Beyond the Usual Trading Algorithms: Technical Requirements for Algorithmic Trading Implementing the algorithm using a computer program is the last part, clubbed with backtesting. The following are needed: Computer programming knowledge to program the required trading strategy, hired programmers or pre-made trading software Network connectivity and access to trading platforms for placing the orders Access to market data feeds that will be monitored by the algorithm for opportunities to place orders The ability and system to backtest the system once built, before it goes live on real markets Available historical data for backtesting, depending upon the complexity of rules implemented in algorithm Here is a comprehensive example: Here are few interesting observations: AEX trades in Euros, while LSE trades in Sterling Pounds Due to the one hour time difference, AEX opens an hour earlier than LSE, followed by both exchanges trading simultaneously for next few hours and then trading only in LSE trading the last hour as AEX closes Can we explore the possibility of arbitrage trading on the Royal Dutch Shell stock listed on these two markets in two different currencies? A computer program that can read current market prices Price feeds from both LSE and AEX A forex rate feed for GBP-EUR exchange rate Order placing capability which can route the order to the correct exchange Back-testing capability on historical price feeds The computer program should perform the following: Read the incoming price feed of RDS stock from both exchanges Using the available foreign exchange ratesconvert the algo of one currency to other If there exists a large enough price discrepancy discounting the brokerage costs leading to a profitable opportunity, then place the buy order on lower priced exchange and sell order on higher priced exchange If the orders are executed as desired, the arbitrage profit will follow Simple and easy! Much of the growth in algorithmic trading in Forex markets over the past years has been due to algo automating certain processes and reducing the hours needed to conduct foreign exchange The steps quantitative traders, and traders using algorithms, follow in order to create their algorithms.
