A stock backtesting engine written in modern Java. And a pairs trading ( cointegration) strategy implementation using a bayesian kalman filter model. 13 Jul 2017 Today we continue this line of thought by defining cointegration and looking at its usage in trading. In particular, we will discuss how a pairs  21 Feb 2019 (The definition of cointegration can be extended to multiple time series, with higher orders of integration.) Other examples of cointegrated pairs:.

23 Apr 2014 Forex pairs trading based on cointegration is essentially a reversion-to-mean strategy. Stated simply, when two or more forex pairs are  Cointegration of currency pairs Trading Discussion. How well are currency pairs Cointegrated as opposed to correlated? Has anyone done  If the portfolio has only two stocks, it is known as pairs trading, a special form of statistical arbitrage. By combining two cointegrated stocks, we can construct a spread that is mean-reverting, even when these two stocks themselves are not. Cointegration is a recognized technique that mathematically expresses t he basic idea of pair trading. Pairs trading involves taking opposite but equal positions in two different underlying securities and are sometimes referred to as “intermarket spreads.” A key to the pairs approach is that it relies on a known, strong correlation (positive or negative) that exists between the two underlyings being considered for a spread. Pairs trading involves in investigating the dependence structure between two highly correlated assets. With the assumption that mean reversion will occur, long or short positions are entered in the opposite direction when there is a price divergence.

It is cointegration, as opposed to correlation that provides the optimal conditions for pairs arbitrage trading. Using the cointegration chart above, it can be seen visually that if the CAC40 (blue line) is above the EuroStoxx50 (orange line), a trading opportunity might be to short the CAC40 at the same time as going long on the EuroStoxx50

Pairs Trading Strategy. The pairs trading strategy uses trading signals based on the regression residual $$\epsilon$$ and were modeled as a mean-reverting process. In order to select potential stocks for pairs trading, the two-stage correlation and cointegration approach was used.
