What is mean reversion trading?
Mean reversion is the idea that when price stretches unusually far from some average — a moving average, VWAP, a session's fair value — it tends to snap back toward it. It's one of the two great families of trading strategies, and it works precisely when its opposite, trend following, doesn't.
The mechanic is simple: define a mean (a moving average, VWAP, or Bollinger midline), measure how far price has stretched from it (often in standard deviations), and bet on a snap-back when the stretch is extreme. You're fading the move — buying weakness, selling strength — which is emotionally the hardest thing to do.
When it works and when it kills you
Mean reversion shines in ranging, balanced markets where there's a genuine fair value to return to. It is lethal in strong trends, where “overextended” price simply keeps extending and your fade gets run over. This regime-dependence is the whole story — the same setup that prints in a range blows up in a trend, which is why a defined stop is non-negotiable.
The psychology trap
Fading a move means acting against what just happened — selling something that's been ripping higher. Every instinct screams not to. Discretionary traders hesitate, miss the entry, then chase late; or they fade without a stop and hope through a trend that doesn't revert. The setup that feels worst is often the valid one, which is exactly why a human's nerve fails here.
Mean reversion done systematically: our Anchor strategy
This is the family our Anchor strategy belongs to: a systematic VWAP mean-reversion model that waits for price to extend a defined number of standard deviations from session VWAP, looks for rejection, and scales targets back toward the mean — with a hard stop for the trend case. The edge is in taking that setup identically every session, which a human can't do reliably but a system that never flinches can.
Mean reversion bets that stretched prices snap back to fair value — gold in ranges, ruin in trends. It means fading moves, the hardest thing emotionally, which is why it's best run by a system with a hard stop, not a nervous hand.
