The two economists were awarded the Nobel memorial prize in economic sciences for their revolutionary work. Furthermore, they established that two or more non-stationary time series are cointegrated so that they can move much from equilibrium. They established the cointegration concept of non-stationary time series to find the correlations. In 1987, Granger and Engle published a paper on this topic.As per them, using linear regression sometimes produces false correlations due to the impact of other factors. However, Granger and Newbold, British economists, argued against linear regression as a technique for analyzing time series for a specified period. Earlier, linear regression was used as a statistical method to find the relation between two or more time series.Ninja Mobile Trader VPS Virtual Private Trading Servers MotiveWave Full-Featured Trading Software Liberty Market Investment Trading Capital Provider Hope all is well with you!ĮT IS FREE FOR TRADERS BECAUSE OF THE FINANCIAL SUPPORT FROM THESE SPONSORS: Alaric Securities EU Licensed Broker/DealerĪMP Global Clearing Futures and FX TradingĪXIA Futures Trader Training and MentorshipĬannon Trading Futures and Options BrokerageĮarn2Trade Education and Funding Challenge Note: I don't know if you're trolling or not because this is a very common technique, if not I apologize for asking. Cointegration also does not necessarily imply that a profitable trading relationship exists. Yes 1245, it can produce a high win rate and often has substantially lower volatility of returns (which is really the key here because this strategy takes a lot of leverage to make substantial returns with unless you trade lower timeframes, which is why I made the above recommendation), but you have to engineer protfolios that have legitimate fundamental relationships (such as the example I gave) or else the spread will undoubtably diverge to unsuitable levels invalidating the strategy and likely costing you a lot of money. This topic is stat arb 101: lecture 2, so enjoy the journey! Here's a link I found, again, if the link doesn't pan out the technique I recommend is called the johansen cointegration test. This technique has shown some interesting results in the past for me. There's also a bunch of techniques for deciding if pairs are beginning to converge or not, but I don't think they're all that valid for me because I target much lower timeframes. Note on that: if all your pairs seem to want to trade at the same time you likely are not beta neutral, which is okay sometimes, but just realize you have that exposure. You also obviously want to analyze multiple relationships at a time, because you spend very little time in the market by only trading when their is suitable divergence. Which holdings and weights to choose is an optimization problem that's too involved for this thread (genetic optimization algorithms work well here because the number of possibilities is a combinatorics problem with millions of solutions often + the fact you need to select the best weights too, making it completely unbounded). I recommend reading the prospectuses of some exchange traded assets and regressing weighted linear combinations of their holding onto the ETF/P/N (which gives you in effect a position in the remaining holdings of the ETF, but it can still work very well). Since you probably arent interested in doing that, I think the "creativity" of your portfolios will likely make or break you. ![]() I recommend you target lower timeframes than excel can really handle and try to investigate "creative" relationships. Simply put, it's my belief that simple pairs trading of only two assets isn't going to get it done with a suitably low amount of 's too easy. There's plenty of examples of augmented dickey fuller tests (ADFs) and Engle Granger tests online, but I feel like in my experience the Engle Granger depends on which variable you choose to regress onto the other, so I recommend the johansen test which can examine multiple cointegration relationships at a time. I've never used this link or excel really for this kind of application.
