Pairs Trading with Cryptocurrencies - Towards Data Science In quantitative trading, we usually work with non-stationary time-series. Often, people consider correlated for two assets when these assets co-move, but this term is mathematically incorrect in this context. Pearson’s correlation is defined for stationary variables only. As we see, this formula uses expected values and standard deviations, but these values are changing over time in non-stationary processes. Correlation formula For these processes, we can define the cointegration. Cointegration refers to some stationary linear combination of several non-stationary time-series. Easy explanation you can find in this video This picture shows two processes (X and Y), and their spread. This is an example of the correlation with no cointegration. Correlation with no cointegration This example is vice versa (cointegration with no correlation) Cointegration with no correlation How to build these processes using Python you can.....

Pairs Trading with Cryptocurrencies – Towards Data ScienceTrading strategy There is no single approach in pairs trading how to calculate the spread and trade this. Some of the approaches use a linear regression and residuals as a spread. We will use the next algorithm. The algorithmic strategy contains these steps: Identify the cointegrated pairs by one of the methods described above (e.g. Engle-Granger). This step should be performed periodically for getting a pair (or several pairs) that will be used in the next steps.Get the price history of assets by length N. Calculate the returns of each asset (e.g. A and B) in the pair 3. Calculate the difference between returns
Calculate the z-score, z-score is the number of standard deviations from the mean a data point is.

Pair Trading Strategies There are two basic types of pair trade strategies; mean reversion and trend following. When employing a forex correlation pair strategy you either believe that a pair that has been moving in tandem will experience a breakdown in its correlation, or you believe that after the correlation has broken down, the pair will revert back to its long term mean. A forex pairs trading strategy that utilizes cointegration is classified as a form of convergence trading based on statistical arbitrage and reversion to mean. This type of strategy was first popularized by a quantitative trading team at Morgan Stanley in the 1980s using stock pairs, although I and other traders have found it also works very well for forex pairs trading, too. By Anupriya Gupta. Pairs trading is supposedly one of the most popular types of trading strategy. In this strategy, usually a pair of stocks are traded in a market-neutral strategy, i.e. it doesn’t matter whether the market is trending upwards or downwards, the two open positions for each stock hedge against each other. Forex pairs trading strategy that implements cointegration is a sort of con-vergence trading strategy based on statistical arbitrage using a mean-reversion logic. This strategy was rst introduced by Morgan Stanley in the 1980s using stock pairs, but traders found that it could be used in FX trading as well. If two pairs are cointegrated, it means that the spread between those pairs is about to ... I buy the under-performing currency pair and sell the out-performing pair. When the spread between the two pairs converges, I close my position for a profit. Forex pairs trading based on cointegration is a fairly market-neutral strategy. As an example, if a currency pair plummets, then the trade will probably result in a loss on the long side and an offsetting gain on the short side. So ... Pairs Trading ist eine beliebte Strategie, aber wie bei allen Strategien bestehen auch hier gewisse Risiken und der Erfolg ist nicht immer garantiert.
