Plan the Trade Before You Take It

A pre-trade checklist does two jobs. Before the trade, it stops you from taking something that isn't in your plan. After the trade, it leaves a written record of what you intended, so you can measure how far your execution drifted from it. Most traders use it only for the first job. The second one is where the learning is.

This post gives you a checklist you can copy, explains why each line is there, and then walks through the part most traders skip: putting the plan next to the result and reading the difference.

Why pilots and surgeons use checklists

Checklists work best in jobs where skilled people make simple mistakes under pressure. In 2007 and 2008, the World Health Organization tested a 19-item surgical safety checklist in eight hospitals across eight countries. Deaths fell from 1.5% to 0.8% and complications from 11.0% to 7.0% after it was introduced. The surgeons didn't learn anything new. The checklist made them do, every time, the things they already knew to do.

Trading has the same failure mode. You know your stop belongs at the invalidation point and your size comes from the stop. You still skip it when a stock is moving and you're afraid of missing it. A checklist doesn't make you smarter. It makes the obvious steps hard to skip.

Atul Gawande's The Checklist Manifesto describes two styles. A read-do list is followed step by step, like a recipe. A do-confirm list is run after you've done the work from memory, as a pause to catch what you missed. A pre-trade checklist is do-confirm: you've found the trade, and now you stop and confirm it before the order goes in.

The pre-trade checklist (copy this)

Every line is a yes or no. If any answer is no, there is no trade.

PRE-TRADE CHECKLIST                         Symbol: ____   Time: ____

CONTEXT
[ ] Inside my trading window, with no scheduled news in the next 15 minutes
[ ] Market condition matches the one this setup is written for

SETUP
[ ] This trade matches a named setup in my plan: ______________
[ ] Every entry condition for that setup is true right now

THE NUMBERS (write them before the order goes in)
[ ] Entry ______   Stop ______   Target ______
[ ] Stop sits where the trade idea is proven wrong, not at a round number
[ ] Target is at least ____R away and inside the day's likely range
[ ] Size = dollar risk ÷ (entry − stop) = ______ shares / contracts

RISK
[ ] This trade's risk fits inside today's remaining loss limit
[ ] I am not adding to a position or trading to win back a loss

STATE
[ ] I would take this trade if my last three trades had been winners

Ten items, under a minute to run. Copy it into your journal, your notes app or a sticky note on the monitor. The format matters less than the habit of filling in the numbers before you click.

Why each line is there

Context. Most setups are written for a particular kind of market: trending, ranging, or quiet. The same pattern in the wrong conditions is a different trade. The news check exists because a scheduled release can move price several times your stop distance in seconds, and slippage on a stop is worst exactly then.

Setup. "This matches a named setup" is the most important line on the list. If you can't name the setup, the trade isn't part of your plan, and its result can't teach you anything about your strategy. Writing the name also tags the trade, so you can later read results by setup instead of as one blended number.

The numbers. This block is the heart of the checklist, and it is why the checklist has blanks, not just boxes. The entry, stop-loss and take-profit define the trade's 1R and its planned risk-reward ratio. The size line forces position sizing from the stop. If you buy at $50.00 with a stop at $48.75 and plan to risk $125, the size is $125 ÷ $1.25 = 100 shares. A size picked by feel is one of the quickest ways for a single trade to become a large loss.

Risk. Your risk per trade is fixed in your plan, but the day's remaining room isn't. If you're already down 2R against a 3R daily limit, a 1.5R trade breaks the limit even though it looks like any other trade.

State. The last line is a test, not a feeling. Ask whether you'd take this exact trade after three wins. If the honest answer is no, you're trading the last result, not the setup.

Why the plan has to be written before the trade

Memory is a poor record of intent. In a classic 1975 study, Baruch Fischhoff found that people told how an event turned out rated that outcome as more predictable than people who weren't told, and didn't notice the shift in their own judgment. That is hindsight bias, and trading is full of it. After a trade hits its target, it feels like you always planned to hold it. After you exit early and price runs on, the early exit feels like the plan.

The only defense is a record made before you know the outcome. That's why the numbers block has blanks to fill in, and why it has to be filled in before the order goes in. Our list of what to track in a trading journal puts the planned entry, stop and target first for the same reason.

Plan vs actual: where the learning is

Once a trade closes, put the plan and the result side by side. Here's one long trade, planned with the checklist above:

Price reached $52.50 about forty minutes after the exit. The trade made money, so a quick review would mark it a win and move on. Measured against its plan, it gave up more than half of what the setup delivered.

Measuring everything in R-multiples, with 1R as the planned $125 risk, the gap breaks into two parts:

• Late entry: paying $50.20 instead of $50.00 cost $0.20 × 100 = $20, or 0.16R.
• Early exit: selling at $51.40 instead of $52.50 cost $1.10 × 100 = $110, or 0.88R.

Planned +2.00R, minus 0.16R, minus 0.88R, equals the actual +0.96R. Nothing is left over, because every dollar of the gap has a cause you can name.

One trade like this is a story. Fifty of them are data. If your reconciliations show that early exits cost you an average of 0.4R a trade, that is a specific, fixable leak, and it probably matters more than any change to your entry rules. Your maximum favorable excursion on each trade tells you how much the market offered; the plan tells you how much you meant to take.

Sorting trades by what the plan tells you

Reconciling against a plan also lets you sort every trade into one of three groups, and each group needs a different fix:

1. Followed the plan, lost. The setup or the market is the question. One loss means little; a run of them across a meaningful sample means the setup needs work.
2. Broke the plan. Execution is the question, whatever the result. A rule break that made money is still a rule break, and it trains the habit you'll pay for later.
3. No plan at all. The trade never passed the checklist. It can't tell you anything about your strategy, only about your discipline.

Do this for a month and the second and third groups are often bigger than you'd guess. That's useful. It means part of the problem is something you control directly, not something the market is doing to you. The weekly trade review process shows how to score these groups each week before you look at P&L.

Common mistakes with a pre-trade checklist

• Making it too long. A twenty-item list gets skipped on fast trades, which are the ones that need it most. Keep it under a minute.
• Writing wishes instead of checks. "Is this a high-quality setup?" can always be answered yes. "Is price above the rising 20-day average?" can't be fudged.
• Filling it in after the entry. Then it records the trade you took, not the one you planned, and the reconciliation shows a perfect match every time.
• Using one list for every setup. The context, risk and state items are shared. The entry conditions belong to each setup, written out in your trading plan.
• Never reconciling. A checklist that is filled in and never compared with the result is just a ritual. The comparison is the point.
