Your worst trades were decided before you entered them. The oversized position, the revenge entry, the setup that wasn't really there — every one of them would have failed a 30-second check at the moment it mattered. Here's the checklist to run before every entry, and how to make it stick when discipline is hardest.
Almost everything in a trading journal is retrospective. You log the trade, tag the setup, note the emotion, and review it later. That loop genuinely works — over weeks, it surfaces patterns you can't see in the moment.
But it has a built-in flaw: by the time the journal tells you a trade was a mistake, the mistake already cost you money. Review is how you learn. It's not how you stop a bad trade that's about to happen.
That takes a gate — a short, fixed set of checks between "I want in" and "I'm in." Pilots don't review the pre-flight checklist after landing. The whole point is that it runs before.
Run these in order. If a check fails, the answer is not "probably fine." The answer is no trade.
Name the setup out loud. If it doesn't have a name — if it's not one of the specific patterns you've defined, journaled, and reviewed — you're not trading your system, you're improvising. Improvised trades can't be evaluated, because there's no standard to evaluate them against. If you find yourself saying "it just looks good," that's your answer.
Before entry, you need three numbers: entry price, stop price, and target. From those, the risk-reward ratio is arithmetic, not opinion. If the trade needs to travel three points to make one, the setup has to win far more often than most setups do just to break even. Decide your minimum acceptable R:R in advance — and let the math veto the trade, not your excitement about it.
The stop also has to be a real level, placed where the trade thesis is invalidated — not a dollar amount you're comfortable losing, dressed up as analysis.
Size comes last, not first. Fixed risk per trade divided by stop distance gives you the position size — that's the whole formula, and we've broken it down with worked examples in our guide to position sizing for day traders. If you picked the number of contracts first and are now hunting for a stop that makes it feel safe, you've inverted the process. Start over.
Max trades per day. No entries in the first two minutes after a news release. No adding to losers. Whatever your rules are, they only work if they're checked at entry time — a rule you only discover you broke during the weekly review is a rule that exists on paper only. If you don't have written rules yet, that's the real finding of this checklist.
This check saves accounts. If your daily loss limit is $500 and you're down $400, the only position size that respects the limit is one that risks $100 or less — which probably means the correct trade is no trade. Prop firm traders should treat this as the sharpest check on the list: a trade that could push you through your daily loss or trailing drawdown limit doesn't have a bad risk-reward — it has an unlimited downside, because the account itself is the stake.
If your last trade was a loser and you're back at the order ticket within minutes, stop. Ask one question: would I take this exact trade if my last trade had been a winner? If the honest answer is no, this isn't a trade — it's an attempt to make the last loss not have happened. That pattern has a name, and it ends accounts. We've written about how to break it in our guide to trading discipline and revenge trading.
"Long above yesterday's high, targeting the overnight high, stop below the breakout bar — because acceptance above that level puts the shorts trapped." One sentence: direction, level, target, stop, reason. If you can't produce that sentence, you don't have a thesis; you have an urge. Writing it down takes ten seconds and doubles as your journal entry's pre-trade note — the single most valuable field to review later.
Here's the uncomfortable truth about pre-trade checklists: the trader who calmly runs all seven checks didn't need them. The checks exist for the moments when you're frustrated, behind on the day, and convinced the next trade fixes everything — and those are precisely the moments a paper checklist gets skipped.
Willpower is a bad enforcement mechanism because tilt disables the very judgment that's supposed to invoke the checklist. Knowing this, you have two options: build so much habit that the checklist survives tilt, or take the checklist out of willpower's hands entirely.
The habit route works for some traders: print the checklist, tape it to the monitor, and require a physical checkmark on all seven items before any entry. Cheap, low-tech, and better than nothing — but it still depends on you choosing to look at it.
The stronger version is software that runs the checks for you and sits between you and the entry. This is exactly what Journali's Trade Check does: you enter the trade you're about to take, it runs the risk-reward math and your risk rules, and it gives you a red or green light — with a 10-second cool-off if you try to override a red. Most journal software analyzes trades after the fact; a blocking pre-trade check is a different category of tool, and it's worth understanding the difference when you're choosing a platform. Our comparison of the best trading journal apps covers which tools offer pre-trade discipline features and which are review-only.
Whichever route you choose, the principle is the same: the decision standard has to be set when you're calm and enforced when you're not.
One last habit that separates traders who use checklists from traders who merely have them: log the trades you didn't take. When a check fails and you pass on the entry, note it — which check failed, and what you were feeling.
Two things come from this. First, you'll see which check does the most work for you; for many traders it's the tilt test, and that's worth knowing about yourself. Second, on the days when the checklist keeps you flat while the market chops everyone else up, you'll have a record that doing nothing was a decision — and a good one. That record is what makes the checklist feel like an edge instead of a cage.
The market will always offer another trade. Your job at the order ticket isn't to find a reason to enter — it's to give the trade seven chances to disqualify itself.
Journali's Trade Check runs your risk-reward and rules before you enter — red light, green light, and a cool-off if you try to force it.
