Trade Efficiency
Trade efficiency compares the profit you actually captured with the maximum favourable move during the trade (MFE capture). Taking $3 of a $5 move is 60% efficiency. Consistently low numbers suggest exits are too early or too late.
Getting the direction right is only half the job; the other half is how much of the move you keep. Trade efficiency compares what you captured with the best price the trade reached. Capturing $3 of a $5 favourable move is 60% efficiency, and tracking it shows whether exits leave too much behind.

Trade efficiency in plain words
Maximum favourable excursion (MFE) is the biggest open profit a position reached while it was open.1
The closer your actual result is to the MFE, the more of the move you captured.1 Efficiency is simply the result divided by MFE.
Tracking MFE and MAE after the trade shows how well-timed your exits were.2
How to measure trade efficiency
Record MFE
Note the best price each trade reached while open.
Record the result
Log the actual exit result in the same units.
Divide
Efficiency = result ÷ MFE; $3 of a $5 move is 60%.
Average many trades
Look at efficiency across many trades, not one.
Test exit rules
Set trailing stops where they keep most winning trades while limiting how much profit gets given back.3
Check post-exit moves
Check post-trade MFE — how far the move went after you exited.2
Worked examples
Example 1 — 60% efficiency
Good captureA hypothetical long reaches +$5 per share, then exits at +$3.
| MFE | $5 |
| Captured | $3 |
| Efficiency | 60% |
The closer results are to MFE, the more complete the use of the favourable move.1
Example 2 — Gave it back
Poor exitA hypothetical trade reaches +$4, then exits at −$1.
| MFE | $4 |
| Result | −$1 |
| Efficiency | −25% |
Reviewing MFE against results shows the timing efficiency of the exit criteria needs work.2
Example 3 — Trailing stop test
Exit improvedA hypothetical trader tests a wider Trailing Stop over 100 trades.
| Avg efficiency before | 35% |
| Avg efficiency after | 48% |
A trailing stop placed to capture the majority of winners lifted average capture.3
High vs low trade efficiency
| Aspect | High efficiency | Low efficiency |
|---|---|---|
| Exit relative to MFE | Close to the best price | Far from it |
| Typical cause | Well-placed exits | Late or early exits |
| Effect on R-multiples | Larger | Smaller |
| Fix | Keep rules | Test exits |

Advantages and disadvantages
Advantages
- Shows how much of each move you keep.
- Separates entry skill from exit skill.
- Gives a clear target for exit tests.
- Works with any market or timeframe.
Disadvantages
- Needs MFE data for every trade.
- 100% efficiency is impossible in practice.
- Chasing efficiency can cut winners short.
- Small samples give noisy averages.
Going deeper
Read as far as you need. Each level builds on the one before it.
The MFE basis
Beginner
MFE is the largest open profit during a trade; landing close to it means you used most of the move.1
Exit timing
Intermediate
Excursion data after the exit shows whether you tend to get out too early or too late.2
Trade-offs
Advanced
TradeStation frames exit placement as capturing the majority of winning trades while limiting profit erosion.3 Higher efficiency on a few trades can lower Expectancy if it cuts big winners, so test on large samples.
Common mistakes
Judging on one trade
Efficiency varies a lot.
Aiming for 100%
No exit catches the exact top.
Ignoring losers
Negative efficiency matters most.
Not logging MFE
No data, no measure.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
Key points to remember
- Efficiency = result ÷ MFE.
- It measures exit quality.
- Track it over many trades.
- Use it to test exits.
- Do not cut winners just to raise it.
