How to Use a Trading Journal and Review Your Trades
Record decisions, grade execution, and turn repeated mistakes into specific rules for the next trading session.
A trading journal is a record of decisions, not a diary of feelings or a scoreboard of wins. Its job is to show whether you followed a defined process and whether the process has evidence behind it. Without consistent records, a memorable win or loss can distort the next decision.
Keep it small enough to complete after every trade. A complicated spreadsheet that is abandoned after a week is less useful than a plain template used for months. The best fields are the ones that let you compare similar trades honestly.
Record the plan before the result
Capture the market, date, direction, setup, entry idea, invalidation level, target, intended size, and order type before or at entry. Add the reason the trade qualified. A screenshot can preserve the context, but a short written reason makes later review faster.
Also record what would make you skip the trade. This creates evidence about restraint, not only execution. A journal should include missed trades and no-trade decisions when they followed the rules; otherwise it rewards activity rather than discipline.
Capture execution and costs
After entry and exit, record actual fill prices, quantity, commissions or trading fees, spread effects where relevant, funding or borrowing costs, and any slippage. Use the platform's own trade report when possible rather than relying on memory.
The difference between planned and actual execution is valuable data. A strategy that looks acceptable with chart prices can fail once real-world costs are included. Link each record to the calculation described in fees, slippage, and break-even, rather than treating net results as an afterthought.
Grade the process separately from profit
Give each trade two simple labels: plan followed or not followed, and outcome positive or negative after costs. This creates four possibilities. A planned loss can be a good process trade. An unplanned profit can be a warning, because it can reinforce a rule break.
Add one short note about the biggest deviation: late entry, early exit, stop moved, oversize, unclear setup, or no deviation. Avoid writing an essay after every position. The weekly review is where patterns deserve more thought.
Review by setup, not by emotion
Once a week or after a chosen number of trades, group records by the same setup and market conditions. Look at count, net result after costs, average planned risk, average win and loss, rule-following rate, and repeated errors. Do not draw strong conclusions from a tiny sample.
Ask precise questions. Did the setup have a defined trigger? Did losses occur after rules were followed? Did certain times or volatility conditions produce more slippage? Did one recurring rule break cause most damage? This makes a journal a feedback loop for your trading plan.
Change one variable at a time
When review identifies a problem, choose one specific experiment: reduce size, require a clearer trigger, avoid a time window, or use a different order rule. Keep the rest of the method stable long enough to observe the effect. Changing entry, stop, target, and size at once produces noise, not learning.
Document the date of the change and why you made it. If a new rule is not followed, that is a process issue to solve before judging the strategy. A backtesting process can help examine a rule historically, but historical results still need cautious forward observation.
Keep the review factual. Replace labels such as “bad market” or “felt wrong” with observable notes: the entry occurred before the trigger, the stop was widened, the spread exceeded the plan, or the setup did not meet the written condition. Specific language makes it possible to count an error and decide whether a rule needs changing.
It also helps to record the conditions in which you did nothing. If the rule required a liquid session or a confirmed close and neither was present, note that the skip was intentional. This prevents hindsight from turning every later move into an imagined missed opportunity.
Protect perspective and privacy
A journal may contain account balances, broker reports, and personal notes. Store it securely and avoid sharing sensitive account information. Use percentages or risk units for review where possible, so the analysis does not depend on public disclosure of balances.
Reviewing less often can be better than obsessing over every tick. Set a scheduled time, inspect the evidence, make one modest process decision, and then return to executing the current rules. The goal is not to eliminate losses. It is to make risk, costs, and behavior visible.
