What is Pairs Trading? How does the strategy work?

Generally speaking, the short side of a trade should be executed and filled before the long order is placed. In addition to the option of manually entering trades, there are some trading programs designed to handle pairs execution. These programs are designed to simultaneously work each side for the trader, particularly for larger orders, in an attempt to hit a pre-specified price ratio. For most traders, such programs are more of a convenience than a necessity because the slippage that occurs during execution is minimal relative to the profit objective of the overall trade.

2. Pairs trading is a popular strategy, but like all strategies, it is not without risks and it is not successful all the time.
3. The pairs trading strategy works not only with stocks but also with currencies, commodities, and options.
4. In the following examples, we use some R code that runs a linear regression between the price series of Exxon Mobil and Chevron to find a hedge ratio and then tests the resulting spread for stationarity.
5. At the same time, you take an equal-sized short position in another asset.

Pairs trading has the potential to achieve profits through simple and relatively low-risk positions. The pairs trade is market-neutral, meaning the direction of the overall market does not affect its win or loss. The difficulty comes when prices of the two securities begin to drift apart, i.e. the spread begins to trend instead of reverting to the original mean. Dealing with such adverse situations requires strict risk management rules, which have the trader exit an unprofitable trade as soon as the original setup—a bet for reversion to the mean—has been invalidated.

Execute the trade

It indicates which security the trader should sell short and which security the trader should buy, and when. The trader using the pairs strategy then short sells the security that is overvalued and goes long on the shares of the security that is trading below value. The strategy enables the aafx trading review trader to maintain ultimate neutrality in the market and generate earnings, regardless of whether the market goes up, down, or sideways. If you’re seeking a lesser-known crypto on an exchange, you’ll likely need to own one of the base currencies listed in a pair before you can trade.

At the same time, you take an equal-sized short position in another asset. They can be anything from two stocks, currencies, commodities, options or exchange-traded funds (ETFs). In this regard, to help minimize the risk of an unexpected event, professional traders can use the pair trading strategy to protect a particular trading idea. To take full advantage of crypto trading pairs, you need to understand base currencies. A base currency is a way to denote an agreed-upon value of different assets. Base currencies are a common tool for comparing exchange rates across fiat currencies in different countries.

Step #3: Apply the BB indicator using 200 periods and 2 standard deviation

For instance, in this case, if the equation above is stationary, that suggests that the mean and variance of this equation remain constant over time. If you make 0.5% per trade (net of fees) and manage to fire 5 trades a month, you will make 2.5% a month. For futures, the dollar value per unit of movement is usually different for different future contracts. Entering an equal dollar amount for both assets usually doesn’t work, especially if the 2 assets are very different.

To do stocks pairs trading well, we should have many pairs (maybe hundreds) running at appropriately low position sizes. This is the most difficult and time-consuming step in the process. It includes selecting a trading universe, constructing and testing a model, if one is to be used, and creating general buy and sell guidelines. An individual trader’s resources and expected trade duration will affect each of these factors, but the structure is functionally the same in all cases. The line of best fit over the whole data set has a slope of 1.68, which we’ll use as our hedge ratio.

It is assumed that the pair will have similar business performance as in the past during the holding period of the stock. There can be many ways of defining forex broker rating take profits depending on your risk appetite and backtesting results. Stop loss is defined for scenarios when the expected outcome does not occur.

Pair trading originated in the 1980s on Wall Street as a hedging method but is commonly used on the crypto market. The strategy is most efficient when there is a discrepancy between two pairs. A trade that sees profits of £1000 on one day, but then the second day sees that fall to £500 has a drawdown of £500. But the loss on activtrades mt4 one position is tempered by profits on the other, and thus the expected drawdown of the strategy can be smaller.

For example, if you own BTC, then you can trade with any pairing listed on an exchange that includes BTC. In an important research paper written by Yale Business School economists Even G. Gatev, William Goetzmann, and K. Geert Rouwenhorst, the authors attempted to prove that pairs trading is profitable. Using a large set of data from 1967 to 1997, the trio found that over any six-month trading period, the pairs trade averaged a +12% return. To distinguish profitable results from plain luck, their test included conservative estimates of transaction costs and randomly selected pairs. The successful pairs trader will look to make money on the inequality between the two markets and close out the trade when the inequality has been reversed.

Another approach: total least squares

In practice, you’ll find that dealing with a changing hedge ratio is more an issue than the statistical significance of the Johansen test. TLS is symmetrical, and will give the same result regardless of our choice of dependent variable. In practical terms, the hedge ratios obtained by OLS and TLS usually won’t differ greatly, but when they do differ, that difference is likely to be significant. For starters, if a series was mean reverting in the past, it may not be mean reverting in the future. Constructed spreads typically mean revert when random, non-structural events affect the value of the components.

Pairs trading

The relative performance of the two markets is the key element, and not just whether the market goes up or down, as is the case for those traders that only go long or short. In order to do the pairs trading, you must devise a trading strategy . Before implementing the strategy in the live market, you must observe all the parameters of the strategy such as maximum drawdown, the average positive trades, negative trades, the profit and loss, etc. Also, a stationary time series means that the pair of stocks is co-integrated and can be traded together by generating trading signals.

This usually results in a profit, although there is always a risk that the price difference will continue to widen and you will make a loss. However, there are times when this relationship breaks down, and the two assets move in opposite directions. When this happens, it presents an opportunity to profit from the price difference between the two assets. To do this, you need to buy the undervalued asset and sell the overvalued one.

The Johansen test is another test for cointegration that generalizes to more than two variables. It is worth being familiar with in order to build mean reverting portfolios consisting of three or more instruments. Such a tool has the potential to greatly increase the universe of portfolios available and by extension the diversification we could potentially achieve. It’s also a data-miner’s paradise, with all the attendant pitfalls.
