Trend following and mean reversion: two basic trading approaches
Ride the move or bet on a return to the average? How the two approaches work and where each struggles.
Most trading styles are variations of two ideas: prices that move tend to keep moving, or prices that move far tend to come back.
Trend following
Trend followers buy strength and sell weakness. They enter after a move has started and stay in as long as the trend continues.
- Typical tools: moving averages, breakouts of recent highs or lows, higher highs and higher lows. See Moving averages and volume.
- Profile: many small losses in sideways markets, a few large gains when strong trends appear.
- Struggles in: ranges and choppy markets, where breakouts fail.
Mean reversion
Mean-reversion traders assume that after a stretch away from an average, the price tends to return to it. They buy weakness and sell strength within a range.
- Typical tools: support and resistance, distance from a moving average, range position. See Trends, support and resistance.
- Profile: frequent small gains, occasional large losses when a range breaks into a trend.
- Struggles in: strong trends, where "cheap" keeps getting cheaper.
Knowing the market regime
Neither approach works all the time. Traders try to recognise whether the market is trending or ranging — for example, by the slope of a long moving average or by volatility. XFasil's AI Market Scanner shows which pairs are at the edge of their 24-hour range or moving strongly, based on real data.
