The short answer

The mean reversion strategy applied to USD/MXN typically targets a 1:1–1:2 risk-to-reward ratio with a hold time of 1–48 hours. USD/MXN is a exotic pair with a 30-pip spread and 800-pip average daily range, which provides plenty of room for this strategy to work. Best timeframes for this combination: H1, H4.

How Mean Reversion Works on USD/MXN

Measure how far price has deviated from the mean (e.g. 2+ standard deviations outside Bollinger Bands, or RSI above 70/below 30). Enter against the move, targeting a return to the mean. Use a stop beyond the extreme. Applied to USD/MXN: High swap rates (positive for short USD/MXN when Banxico rates are above Fed). Wide pip ranges. Moves on Banxico decisions, US trade policy, and EM risk sentiment. Bet that price will return to a statistical average (moving average, Bollinger mid-band, or VWAP) after moving too far away from it.

    Don't fade strong trends — mean reversion works in ranges, not trends

Best Conditions

Range-bound markets, low-trend environments. Works well on EUR/GBP, AUD/NZD, and other low-volatility crosses. For USD/MXN specifically, the best session is the New York session. Trade during that window for tightest spreads and deepest liquidity.

When This Setup Fails

Trending markets. Fading a strong trend is how traders blow up — mean reversion assumes the trend doesn't exist, and sometimes it does. On USD/MXN, also watch out for spread blowouts during off-hours that can trigger stops prematurely.
