The short answer

The mean reversion strategy applied to USD/SGD typically targets a 1:1–1:2 risk-to-reward ratio with a hold time of 1–48 hours. USD/SGD is a exotic pair with a 3-pip spread and 40-pip average daily range, which can be tight — make sure the spread doesn't eat your edge. Best timeframes for this combination: H1, H4.

How Mean Reversion Works on USD/SGD

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/SGD: Low volatility for an exotic pair because MAS actively manages the SGD band. Moves on US data more than SGD data. Popular with Asian session range traders. Bet that price will return to a statistical average (moving average, Bollinger mid-band, or VWAP) after moving too far away from it.

Mean Reversion Rules for USD/SGD

  1. 1

    Step 1

    Identify a mean (20 EMA, Bollinger mid-band, or session VWAP)

  2. 2

    Step 2

    Wait for price to extend 2+ standard deviations from the mean

  3. 3

    Step 3

    Confirm with RSI > 70 (sell) or < 30 (buy)

  4. 4

    Step 4

    Enter against the move with a stop beyond the recent extreme

  5. 5

    Step 5

    Target: the mean itself (conservative) or 1 SD back (aggressive)

  6. 6

    Step 6

    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/SGD specifically, the best session is the Asian 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/SGD, also watch out for spread blowouts during off-hours that can trigger stops prematurely.
