Maximum Continuation Excursion (MCE)

What did the market do after you closed? MCE measures the move you missed — and reveals whether your exit was on time or premature.

Maximum Continuation Excursion (MCE) is the best favorable move the market made after you closed a position, measured in a window that scales with how long you held the trade. Positive MCE means the move kept going without you. Negative MCE means price reversed soon after your exit, which is the cleanest signal you can get that your timing was right.

MCE measures the favorable continuation in the post-close window, bounded by min(4h, max(5min, duration × 5)).

The gap MFE and MAE leave open

Maximum Favorable Excursion and Maximum Adverse Excursion both end at the exit bar. They tell you how much heat you sat through and how much profit was on the table while the position was open. Neither of them has anything to say about the bar after your close. If your goal is to find out whether you exited too early, MFE and MAE will not answer the question, because the data they look at stops the moment you flatten.

We added MCE to the Tradeways journal because we needed a single number to answer "did I leave too early?" across hundreds of trades. MFE and MAE describe the trade while you held it. MCE picks up where they stop, at the exit, and looks at what happened next.

What MCE measures

MCE is the highest unrealized P&L you would have had if you had stayed in, scanned over every 1-second bar in a post-close observation window. We compute it from the same Databento 1-second OHLCV feed we use for MFE and MAE, so the three numbers are directly comparable.

Three signals come out of this:

  • Large positive MCE. The move kept going without you. Your exit was early relative to what the market offered.
  • MCE near zero. Clean exit. The market neither extended much nor reversed sharply.
  • Negative MCE. Price moved against your direction shortly after your close. Your exit timing caught the turn.

This is a Tradeways-original metric. It is not in standard literature. The gap it fills is narrow but real: every exit-quality discussion you have ever read talks about "I exited too early" as a feeling, and MCE turns it into a number on every closed trade.

Why the observation window scales

A 30-second scalp does not care what happens 4 hours later. By then the regime has changed, the session has moved on, the order flow that drove the trade is gone. A 90-minute swing, on the other hand, might still be relevant 7 hours later because it lives on the same daily structure.

The duration × 5 rule keeps the observation window proportional to the trade's own timescale. The 5-minute floor stops noise from dominating ultra-short trades. The 4-hour cap stops a multi-day position from being judged against the next morning's open, which has nothing to do with your exit. Concrete examples:

  • A 90-second scalp gets max(5min, 90s × 5) = max(5min, 7.5min) = a 7.5-minute window.
  • A 15-minute day trade gets max(5min, 75min) = a 75-minute window.
  • A 30-minute swing gets a 2.5-hour window.
  • A 2-hour position hits the cap at 4 hours.

The post-close window scales with the trade's own timescale. A 90-second scalp and a 90-minute swing get different observation windows because what comes 'after' means different things.

Reading positive MCE

Large positive MCE means you exited too early. The market kept moving in your direction and you were not there to take it. One trade is anecdote, but a pattern of large positive MCE on the same setup is a structural finding about your exit rule.

Look at it by setup. If MCE on your scratch exits (the ones where you cut early because "something felt off") is consistently large and positive, your stop-loss-tightening logic is firing on noise rather than on real reversals. The market was not turning, you were just nervous, and the metric proves it. If MCE on your target exits is consistently large and positive, your targets sit too close to entry for that setup and you should test moving them.

Reading negative MCE

Negative MCE is your strongest evidence that an exit rule is real. A consistent pattern of negative MCE on a particular setup means that, again and again, you got out and the market then reversed against you. That is not noise. That is your exit rule capturing turning points.

This is the rarest reading of the three, because most exits are either approximately on time (MCE near zero) or early (positive MCE). When you find a setup where the median MCE across 50+ trades is meaningfully negative, you have found something worth protecting. Do not change that rule. Size up the setup instead.

MCE across many trades, not one

The point of MCE is never the number on trade #47. It is the median across your last 100 trades, sliced by setup. One trade tells you nothing because the post-close window is dominated by whatever random thing the market did that afternoon. A hundred trades smooth out the randomness and let the structure of your exits show through.

A concrete rule of thumb: a setup with median MCE of +0.3R is leaking roughly 30% of risk per trade in unrealized continuation. Over 100 trades that is 30R of missed move. That number changes how you think about whether the setup is "good enough" or whether the exit needs rework.

What MCE cannot tell you

MCE answers a narrow question and you should not stretch it. It does not know your re-entry costs (slippage, commissions, the cost of getting stopped out before the continuation arrived). It does not know your psychological budget for sitting in a trade longer. It says "the move kept going", not "you should have stayed in." Staying in usually means accepting a wider stop, and a wider stop changes the risk side of the equation in ways MCE does not see.

Treat it as one of three numbers, not as a verdict. The full picture comes from looking at MFE, MAE and MCE all three together: what was available while you held, how much heat you took to hold it, and what you left behind after you walked away.

Putting MCE to work

Once MCE is logged on every closed trade, the weekly review collapses into a single loop.

The point is not to feel bad about exits you missed. It is to convert "I think I exit early" into a number that updates every week, and then to find the one or two setups where the number is large enough to be worth fixing first.
