Mean reversion in forex trading

Mean reversion is a concept based in statistics that assumes prices will move away from their ‘mean’ value in the short term while always returning to it in the long term. This theory cannot be confirmed given that markets are to an extent random and thus unpredictable, but there are many historical examples to support its relevance in asset classes like forex, interest rates, and stock volatility.* Historical mean reversion Mean reversion is especially popular among traders in forex markets. Even though many currency pairs can experience multiyear price extremes and high volatility, across decades the same pairs are widely viewed as mean reverting. The thirty-year chart of EUR/USD below illustrates how often the pair crosses the long-term mean. EUR/USD historical prices Managing price extreme risk While forex pairs may revert to historical means over a long horizon, positions can still move against traders towards extremes in the short term. There are several methods traders can employ to mitigate such risks: Scaling Scaling involves reducing lot size in order to save enough capital to act again if the market moves against you. By doing so, traders are more likely to capture the price extreme. In the example below, breaking the trade into four orders of 0.25 lots as the price moves higher allows the trader to profit from moves down from 158.00. However, if the market continued to trade higher, then the trader would still have a full 1.0 lot of risk and could experience large losses.

By setting exit prices upon entry using stop-loss orders, traders can automate management mechanics without having to actively enter closing orders in a moving market. In the example below, setting a stop-loss order at 156 when entering the trade at 154 allows the trader to elect whether or not to open a new position at 158 without holding the initial position all the way to the price extreme. Stop-loss orders can serve as a risk mitigation tool to limit adverse price action, but it should be noted that they do not guarantee a fill at a specified price; stop-loss orders technically trigger market orders when a price level is hit, and that market order can include slippage.

Price extremes can exist simultaneously in multiple currency pairs; taking several different mean reversion positions reduces exposure to a single currency pair that could experience price extremes for extended periods of time. EUR/JPY and GBP/AUD historical prices as diversification example How to trade forex using mean reversion Open an account to get started, or practice on a demo account Choose your forex trading platform Open, monitor, and close positions on forex pairs Trading forex markets using mean reversion requires an account with a forex provider like IG.
