Mean Reversion Trading: What to Track in Your Journal
Mean reversion fades the stretch and bets on the snap back. Done with rules, it is an edge; done on a hunch, it is catching knives. The journal is how you tell which one you are doing.

What mean reversion trading is
A mean reversion trade bets that price has stretched too far from a reference — a moving average, a value area, a prior range — and will revert toward it. Instead of buying strength, you are buying weakness, or selling strength, on the expectation that the extreme does not hold.
The risk is structural: you are trading against the current move, so being early looks exactly like being wrong, and a trade that does not revert can run a long way against you. That makes context and exits the whole game, and both are things you can only judge by reviewing how your reversion trades actually played out.
Ideal setups
Reversion setups worth taking
Stretched from the mean
Price is meaningfully extended from your reference, not just slightly off.
Context supports it
The broader structure is range-bound or balancing, not a strong one-way trend.
Evidence of exhaustion
Slowing momentum or a rejection, rather than fading purely on "it is too high."
Defined invalidation
A clear level beyond which the stretch is real continuation, not an extreme.
The rules
Rules to write into your play
Reversion punishes vague plans hardest, because adding to a loser feels like conviction. Define:
Entry trigger
What confirms exhaustion enough to enter — not just distance from the mean.
Hard stop
A fixed invalidation. Mean reversion without a stop is how accounts blow up.
No-averaging rule
Decide in advance whether adding to a losing reversion is allowed. Usually it should not be.
Target
Where you expect reversion to — often the mean itself — and where you take profit.
Journal checklist
What to track on every reversion trade
Context check
Was the broader structure actually range-bound, or did you fade a trend?
Stretch evidence
What told you it was extended — and was it real or wishful?
Re-entry behavior
Did you respect the stop, or average down and call it conviction?
Behavioral tags
Tag the trades where you fought the tape after invalidation.
The scorecard
How to score your execution
Grade what you controlled so the review separates a sound process from a lucky bounce:
Entry
Did you wait for your trigger, or fade on a hunch?
Stop
Did you set and honor the invalidation?
Exit
Did you take the reversion target, or get greedy past the mean?
Sizing
Risk within limit, with no averaging down?
You grade these yourself. Mettle structures the self-report so it is fast and comparable week to week; it does not objectively grade your fills.
FAQ
Is mean reversion trading riskier than trend following?
It can be, because you trade against the current move, so a failed reversion can run far. That is exactly why a written invalidation and an honest review of whether you respected it matter more here than in most strategies. Mettle is built for that review, not for picking the trades.
Are the scores objective or self-reported?
Self-reported, by design. No software can see whether you hesitated, chased, or broke your own rule — only you can. Mettle structures that self-report so it is fast, honest, and comparable week to week, and keeps its analysis grounded in what you actually logged.
How do I stop averaging down on reversion trades?
Write a no-averaging rule into your play, then tag every trade where you broke it and let the weekly review show the rate. Averaging down survives because it hides; once it is a tagged, counted habit in front of you, it shrinks.
Is Mettle free to start?
Yes. You get full access free for 14 days with no card. We only ask for a card once you have reviewed three sessions, after the product has earned a place in your routine.
