Good Losses and Bad Wins

A good loss follows the plan and stays within the planned risk — sometimes it is simply an unlucky trade. A bad win makes money while breaking the rules — a lucky trade. Rewarding bad wins teaches habits that eventually cost money.

A trade can follow every rule and still lose — that is a good loss. Another can break the rules and make money — that is a bad win. Judging trades by process instead of outcome stops luck from teaching you bad habits.

Good losses and bad wins in plain words

The SEC's investor bulletin warns about the disposition effect: holding losing investments too long and selling winning investments too soon.1 A good loss is the opposite — a planned exit at the planned risk.

Having a Trading Plan only helps if you have the discipline to follow it.2

A journal shows whether you followed your strategy or just reacted to the market — that is how you separate a bad win from a good loss.3

How to grade trades by process

  1. Plan first

    Write entry, Stop Loss, target and size before the trade.

  2. Grade the process

    Score whether each rule was followed, separately from the result.

  3. Grade the outcome

    Record the result in R as a separate field.

  4. Sort into four boxes

    Good win, good loss, bad win, bad loss.

  5. Review bad wins

    Review the journal for habits that keep leading to losses.3

  6. Reward the process

    Treat a rule-following loss as a success of Trading Discipline.

Worked examples

Example 1 — Good loss

Good loss

A hypothetical trader enters on plan, the stop is hit at −1R as planned.

Example 1 — Good loss — calculation
Rules followedYes
Result−1R

Sticking to the plan avoided an unnecessary larger loss, so this is a good loss.2

Example 2 — Bad win

Bad win

A hypothetical trader removes the stop, the price drops then recovers, and the trade closes +2R.

Example 2 — Bad win — calculation
Rules followedNo
Result+2R

The money was made while reacting to the market rather than trading the strategy, so it is a bad win to review.3

Example 3 — Bad win repeated

Habit costs money

The same hypothetical trader removes stops again, and this time the price keeps falling.

Example 3 — Bad win repeated — calculation
Planned loss−1R
Actual loss−6R

Refusing to admit the mistake and holding on turned a small, planned loss into a big one.4

Where this helps

  • Journal reviews

    Grading process in a Trading Journal.

  • Coaching

    Discussing decisions, not just Profit and Loss.

  • After streaks

    Keeping calm through normal Drawdowns.

  • Rule changes

    Changing rules on evidence, not single results.

Advantages and disadvantages

Advantages

  • Separates skill from luck.
  • Rewards discipline.
  • Reduces emotional reactions to single trades.
  • Makes reviews more useful.

Disadvantages

  • Grading process takes effort.
  • Rules themselves may be flawed.
  • Bad wins feel good, so they are hard to criticise.
  • Needs honest self-scoring.

Going deeper

Read as far as you need. Each level builds on the one before it.

Outcome is not process

Beginner

Because a journal records decisions as well as results, you can grade the two separately.3

Why bad wins are dangerous

Intermediate

The SEC-published review finds the disposition effect widely operative and counterproductive; a bad win that came from holding a loser reinforces exactly that habit.5

Emotions

Advanced

Even a careful plan can fall apart in seconds when panic or euphoria takes over.4 Scoring process helps you notice when that happened, even on a winning trade.

Common mistakes

  1. Celebrating every win

    Some wins were rule breaks.

  2. Blaming every loss

    Some losses were well executed.

  3. Changing rules after one trade

    Single results are noisy.

  4. Skipping the process grade

    Then luck drives learning.

Check your understanding

Test yourself before moving on. Each answer comes with an explanation.
