Trading Strategies Headlines 

There are many simple yet effective strategies available which are common across trading instruments or specific to a few/single trading instruments. As per my experience, here are a couple of most basic Algo trading strategies which are common ac.

The strategy will increase the targeted participation rate when the stock price moves favorably and decrease it when the stock price moves adversely. This is sometimes identified as high-tech front-running. 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: We start by building an algorithm to identify arbitrage opportunities. Here are few interesting observations: AEX trades in euros, while LSE trades in British pound sterling Due to the one-hour time difference, AEX opens an hour earlier than LSE, followed by both exchanges trading simultaneously for the next few hours and then trading only in LSE during 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?

Read the incoming price feed of RDS stock from both exchanges. Using the available foreign exchange rates, convert the price of one currency to the 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. Remember, if you can place an algo-generated trade, so can the other market participants.

You will end up sitting with an open position, making 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. Accordingly, you will make your next move.

You have based your algorithmic trading strategy on the market trends which you determined by using statistics. This method of following trends is called Momentum Based Strategy. This is triggered by the acquisition which is a corporate event. If you are planning to invest based on the pricing inefficiencies that may happen during a corporate event before or after , then you are using an event-driven strategy.

Bankruptcy, acquisition, merger, spin-offs etc could be the event that drives such kind of an investment strategy. These strategies can be market neutral and used by hedge fund and proprietary traders widely. Statistical Arbitrage When an arbitrage opportunity arises because of misquoting in prices, it can be very advantageous to algorithmic trading strategy.

At this stage many of the strategies found from your pipeline will be rejected out of hand, since they won't meet your capital requirements, leverage constraints, maximum drawdown tolerance or volatility preferences. The strategies that do remain can now be considered for backtesting.

However, before this is possible, it is necessary to consider one final rejection criteria - that of available historical data on which to test these strategies. Obtaining Historical Data Nowadays, the breadth of the technical requirements across asset classes for historical data storage is substantial. In order to remain competitive, both the buy-side funds and sell-side investment banks invest heavily in their technical infrastructure.

It is imperative to consider its importance. In particular, we are interested in timeliness, accuracy and storage requirements. I will now outline the basics of obtaining historical data and how to store it. Unfortunately this is a very deep and technical topic, so I won't be able to say everything in this article. However, I will be writing a lot more about this in the future as my prior industry experience in the financial industry was chiefly concerned with financial data acquisition, storage and access.

In the previous section we had set up a strategy pipeline that allowed us to reject certain strategies based on our own personal rejection criteria. In this section we will filter more strategies based on our own preferences for obtaining historical data. The chief considerations especially at retail practitioner level are the costs of the data, the storage requirements and your level of technical expertise.

We also need to discuss the different types of available data and the different considerations that each type of data will impose on us. Let's begin by discussing the types of data available and the key issues we will need to think about: Fundamental Data - This includes data about macroeconomic trends, such as interest rates, inflation figures, corporate actions dividends, stock-splits , SEC filings, corporate accounts, earnings figures, crop reports, meteorological data etc.

This data is often used to value companies or other assets on a fundamental basis, i. It does not include stock price series. Some fundamental data is freely available from government websites.

Other long-term historical fundamental data can be extremely expensive. Storage requirements are often not particularly large, unless thousands of companies are being studied at once. News Data - News data is often qualitative in nature. It consists of articles, blog posts, microblog posts "tweets" and editorial. Machine learning techniques such as classifiers are often used to interpret sentiment. This data is also often freely available or cheap, via subscription to media outlets.

The newer "NoSQL" document storage databases are designed to store this type of unstructured, qualitative data. Asset Price Data - This is the traditional data domain of the quant. It consists of time series of asset prices.

Equities stocks , fixed income products bonds , commodities and foreign exchange prices all sit within this class. Daily historical data is often straightforward to obtain for the simpler asset classes, such as equities. However, once accuracy and cleanliness are included and statistical biases removed, the data can become expensive.

In addition, time series data often possesses significant storage requirements especially when intraday data is considered. Financial Instruments - Equities, bonds, futures and the more exotic derivative options have very different characteristics and parameters. Thus there is no "one size fits all" database structure that can accommodate them. Significant care must be given to the design and implementation of database structures for various financial instruments.

We will discuss the situation at length when we come to build a securities master database in future articles. Frequency - The higher the frequency of the data, the greater the costs and storage requirements.

For low-frequency strategies, daily data is often sufficient. For high frequency strategies, it might be necessary to obtain tick-level data and even historical copies of particular trading exchange order book data. Benchmarks - The strategies described above will often be compared to a benchmark. This usually manifests itself as an additional financial time series.

For a fixed income fund, it is useful to compare against a basket of bonds or fixed income products. The "risk-free rate" i. All asset class categories possess a favoured benchmark, so it will be necessary to research this based on your particular strategy, if you wish to gain interest in your strategy externally.
