Key takeaways
- A written one-page plan moves decisions from the heat of the market to a calm moment.
- Keep the plan small: markets, setup, entry, stop and target, size, limits and no-trade conditions.
- Record every trade, including whether you followed the plan, and review weekly in R.
- Name your biases and attach a counter-rule to each; revenge trading and moving stops cost the most.
- Routines and hard limits create discipline when willpower is weakest.
- Change the method only after enough plan-following trades; otherwise fix the process.
Two traders can follow the same method and get opposite results, and the difference is rarely the method. It is whether they do the same thing every time: the same sizing, the same stop, the same patience after a loss. Discipline is not willpower; it is a plan written when you are calm, a journal that shows you the truth about your behaviour and routines that make the right action the default. This guide shows how to write a one-page trading plan, how to keep a journal you will actually use, which biases cost the most money and how to build rules that survive a bad day.
Why a written plan beats a good intention
In a live market you are making decisions under uncertainty, with money at stake, which is the worst time to invent rules. A written plan moves those decisions to a calm moment. It answers in advance what you trade, when you enter, where you place stops, how much you risk and when you stop for the day. Its value is not that it predicts the market but that it makes your behaviour consistent, which is the only way to learn whether your method works. Without a plan, every result is a mixture of method, mood and luck, and you cannot tell them apart.
The one-page trading plan
| Section | Question it answers | Example entry |
|---|---|---|
| Markets and sessions | What do I trade and when? | EUR/USD and GBP/USD during the London session |
| Setup | What conditions must be true to enter? | Price retests a prior level with confirmation on the hourly chart |
| Entry | How exactly do I enter? | Limit order at the level, or market order on confirmation |
| Stop and target | Where am I wrong, and where do I take profit? | Stop beyond the swing; target at least twice the stop distance |
| Position size | How much do I risk? | 1% of equity per trade; size from the stop distance |
| Limits | When do I stop? | Two losing trades in a day, or 3% daily loss, ends the session |
| No-trade conditions | When do I stay out? | Ten minutes either side of high-impact news; when tired or distracted |
| Review | How do I check the plan works? | Weekly journal review; monthly expectancy in R |
The trading journal
A journal is the feedback loop that turns experience into improvement. Each trade gets a record made at the time of the trade and completed after it closes. The point is not a diary of feelings but a dataset that reveals patterns: which setups pay, which times of day lose money, which emotional states precede mistakes and whether your results come from method or from rule-breaking.
| Field | Why record it | Example |
|---|---|---|
| Date, time, market, direction | Finds patterns by session and instrument | Tue 08:40 UTC, EUR/USD, long |
| Setup name and reason | Shows which setups work | Level retest with confirmation |
| Planned entry, stop, target and size | Compares the plan with what happened | Entry 1.0850, stop 1.0820, target 1.0910, 0.2 lot |
| Actual entry and exit | Reveals slippage and early or late exits | Filled 1.0851; exited 1.0910 |
| Result in R and money | Measures the method independent of size | +1.9R, +$114 |
| Followed the plan? (yes or no) | Separates method quality from discipline | Yes |
| Emotion and condition before and after | Links behaviour to outcomes | Calm; slightly rushed after a morning loss |
| Screenshot of the chart | Allows honest review later | Entry and exit marked |
How to run a weekly review
- Count and classify the trades. How many trades, how many followed the plan, how many did not.
- Compute the results in R. Total R, win rate, average win, average loss.Tip: Compare plan-following trades with plan-breaking ones separately.
- Find the biggest leak. Usually one thing: moving stops, oversizing after a loss, trading outside the plan.
- Write one change for next week. A single, specific, testable rule beats a list of resolutions.
- Review the best and the worst trade. Ask what was repeatable in the best and avoidable in the worst.
The biases that cost the most
Cognitive biases are not character flaws; they are normal shortcuts that happen to be expensive in markets. Naming them helps you notice them in the moment. The table lists the most common, what they look like in practice and a rule that counters each.
| Bias | What it looks like | Counter-rule |
|---|---|---|
| Loss aversion | Holding losers too long and taking small profits early | Fixed stop and target before entry; no moving stops further away |
| Overconfidence | Increasing size after a winning streak | Change size only by written rules, never after a streak |
| Recency bias | Treating the last few trades as the new normal | Judge the method over a large sample, not the last week |
| Confirmation bias | Seeking only information that supports your trade | Write what would prove you wrong before entering |
| Revenge trading | Trading larger or recklessly to win back a loss | A daily loss limit that ends the session |
| FOMO | Entering because the price is moving without you | Only enter at setups from the plan; missed trades cost nothing |
| Gambler's fallacy | Believing a loss makes a win more likely | Each trade is independent; size from risk, not from streaks |
Routines that make discipline automatic
- A pre-session checklist: calendar of events, levels marked, limits written, state of mind noted.
- Fixed trading hours, with the platform closed outside them.
- A hard stop after a daily loss limit or a set number of consecutive losses.
- Orders with stops attached at entry, so the exit is decided before emotion arrives.
- A cooling-off rule: after a large loss, no trades for a set period, with a written note of what happened.
- A weekly review at the same time every week.
- Rest, sleep and breaks: tired traders break rules more often.
When the plan stops working
Every method has losing periods and some stop working. The journal is how you tell the difference. If results fall but you followed the plan, the issue may be normal variance and the right response is to keep size small and keep recording. If you did not follow the plan, the issue is discipline and the right response is to reduce size and fix the process. Only change the method after a large enough sample of plan-following trades shows a persistently negative expectancy, and change one thing at a time so you can learn from the result.
Frequently asked questions
How long should a trading plan be?
One page is enough. If you cannot follow it from memory, it is too long.
What should I record in a trading journal?
The plan, the actual trade, the result in R and money, whether you followed the plan, your emotional state and a chart screenshot.
How many trades do I need before I judge my strategy?
More than you think. Thirty trades are rarely enough; a few hundred give a clearer picture. Judge plan-following trades separately.
Is it normal to break my own rules?
Yes, especially after losses. That is why limits are written in advance and why you track compliance in the journal.
Should I increase size after a winning streak?
Not by feeling. Overconfidence after wins is a common cause of large losses. Change size only by written rules.
What is revenge trading?
Trading larger or recklessly to win back a loss. A daily loss limit that ends the session is the simplest remedy.
Do I need to trade every day?
No. Staying out when conditions do not match your plan is part of the plan, and missed trades cost nothing.
When should I take a break?
After reaching a daily or weekly loss limit, after several rule breaks in a row or when you are tired, stressed or distracted.
