Thanks for telling us about the problem. To begin, I did some basic data analysis to better understand the nature of the data. The above example is a ‘simple’ arbitrage.

This is exactly what our linear mean-reversal strategy does. The results in validation seemed very promising! As mentioned before, in addition to the familiar time ernke mean reversion to which we have devoted all our attention so far, there is the phenomenon of cross-sectional mean reversion, which is prevalent in baskets of stocks. He does a good job of covering the most common errors and biases in developing a quantitative trading system, including why those errors hurt and how to figure out when a strategy chxn them.

Does this mean it is of no use to the retail quant? Also, if traders refrain from taking overnight positions in stock pairs, they may be able to avoid the changes in fundamental corporate valuations that plague longer-term positions mentioned above.

In any event, this was a fun exercise where I ernle a great deal about insider trading and its impact on future returns.

Which price should we use to backtest our strategies?

It is not an academic treatise on financial theory. If your backtesting and live trading programs tradung one and the same, and the only difference between backtesting versus live trading is what kind of data you are feeding into the program algoruthmic data in the former, and live market data in the latterthen there can be no look-ahead bias in the program.

In this application we are concerned with only one mean-reverting price series; we are not traidng with finding the hedge ratio between two cointegrating price series. Another way to say this is that the high return is likely the result of data-snooping bias, and the long drawdown duration will make it unlikely that the strategy will pass a cross- validation test.


As H decreases toward zero, the price series is more mean reverting, and as H increases toward 1, the price series is increasingly trending; thus, H serves also as an indicator for the degree of mean reversion or trendiness.

For instance, the importance of transaction costs and risk management are outlined, with ideas on where to look for further information.

There is a general approach to trading strategy construction that can min- imize data-snooping bias: That is, the program does vhan go poll prices or news items at the end of each bar and then decide what to do.

Overall, performance for each of the algorithms tested were fairly similar, but in the end, the random forest prevailed. By doing this we have just turned the out-of-sample data into in-sample data. Library of Congress Cataloging-in-Publication Data: The outcome of this pro- cess is often a modified strategy that regains profitability.

Examples of mean-reverting strategies will be drawn from interday and intraday stocks models, exchange-traded fund ETF pairs and triplets, ETFs versus their ernoe stocks, currency pairs, and futures calen- dar and intermarket spreads.

We describe later how we determine this probability distribution. But the concept of cointegration easily extends to etnie or more assets. Every tick in the FX case, a tick is a new quote triggers a recalculation of all the values in all of the cells of the spreadsheet.

Without additional homework, you could end up depleting your capital accounts. Published simultaneously in Canada. The logic is that high oil price drives up inflation, and gold prices are positively correlated with inflation.

Despite the seeming irrelevance to a retail trader, the book actually contains a wealth of information on how a “proper” quant trading system should be carried out. Even if you pair them up in some sensible way e. His discussions of how regime changes affect strategies,and of risk management, are invaluable bonuses. We are dealt one coin at a time, and if we suffer a string of losses, our capital will be depleted and we will be in debtor prison if we keep playing.


The most common com- bination is that of two price series: A long-only crude oil futures strategy returned 20 percent inwith a Sharpe ratio of 1.

A good exposition can be found in Sorensen, I have already written a beginner’s guide to quantitative tradingbut one article cannot hope to cover the diversity of the subject. A neural net trading model that has about nodes gener- ates a backtest Sharpe ratio of 6. It is especially difficult for these platforms to trade strate- gies that involve arbitrage between different asset classes, such as between futures and stocks or currencies and futures.

No pesky options pricing theories will be discussed, as the emphasis is on arbitrage trading. The returns, not the prices, are the ones that usually randomly distribute around a mean of zero.

Also, I focused on equity trades rather than derivatives for similar reasons -it can be difficult to interpret the motivations behind various derivative trades. Advanced subjects and round-up: The best books I have found for this purpose are as follows: Since this phenomenon occurs most often for stock baskets, we will discuss how to take advantage of it in Chapter 4 when we discuss mean-reverting strategies for stocks and ETFs.

My alarms always go off whenever I hear the term neural net trad- ing model, not to mention one that has nodes. Just a moment while we sign you in to your Goodreads account. They have contributed valuable insights to me that may not be easily accessible in any public forums.

For exploratory data analysis and model building, I used the R programming language. In the discrete form of 2. In actuality, this strategy algorithmi most certainly perform poorly because in many cases the company whose stock dropped the most in the previous day will go on to bankruptcy, resulting in percent loss of the stock position.

That is because the fundamental economics of a basket of stocks changes much more slowly than that of a single company.
