Your Style Decides Your Journal Columns

You searched for what to record in a trading journal, and every answer looks the same: date, instrument, direction, entry, exit, stop, size, result, a screenshot, a box for notes. That list is not wrong. It is just not yours.

A journal is not a receipt. It is an instrument, and an instrument is built to measure one thing well. The thing you need it to measure is the mistake you keep repeating. A scalper and a swing trader do not repeat the same mistake, so they should not be filling in the same sheet.

A template built to suit everybody can only ask the questions everybody shares. Anything a template can ask every trader is, by definition, something that does not separate one trader's mistakes from another's. Entry price, exit price, direction, result — these are true of every trade ever placed. They record the outcome, not the decision that produced it.

Sort a generic journal by result and you learn which trades lost. You already knew that. What you want to know is what the losing trades had in common, and the common factor is almost always behavioural: the hour, the repetition, the size, the holding period, the re-entry straight after a stop-out. None of those have columns on the standard sheet, so none of them can be sorted, counted or seen.

The second failure is quieter. A generic journal gives a false sense of diligence. You fill it in every day. It looks like discipline. But it is carefully recording the parts of the trade you were never going to get wrong twice, and leaving blank the part you get wrong every week.

A scalper takes a lot of trades, holds them briefly, and pays cost in proportion to how often they click. The damage, when there is damage, rarely comes from one bad idea. It accumulates in the gaps between trades and in the fine detail of execution.

So the sheet has to be fine-grained in time and in cost. Useful columns include: the spread at the moment of entry; the fill price against the price you intended; how many seconds or minutes the position was open; the trade's number in that session; how long it had been since the previous trade closed; whether the entry was a planned setup or a re-entry after being stopped; and which session you were in.

Each of those exists to catch something specific. Trade number in the session catches the drift from trading a plan to trading boredom. Minutes since the last trade catches revenge clicks. Spread at entry catches the habit of taking a marginal setup in a thin window where cost quietly eats the edge. Fill against intended price catches chasing. Sort twenty scalps by "trade number in session" and the shape of your day shows up in a way no screenshot can give you.

Notice that none of those columns describe the market. They describe you. That is the point. A scalper's recurring errors are errors of repetition and cost, so the diagnostics are about repetition and cost.

For a swing trader the entry decision is a small slice of the trade. Most of what can go wrong goes wrong afterwards, over hours and days, in private, with no candle to blame.

The sheet has to cover the holding period. Useful columns include: days held; which scheduled events the position was open across; whether the stop was moved, in which direction, and on what evidence; whether you added to the position; how many separate times you opened the chart while it was live; whether the original reason for the trade still existed when you closed it; and what the risk was as a fraction of the account, because a position open across days sits alongside whatever else you take while it runs.

"Stop moved and why" is the single column most swing journals are missing. Moving a stop away from price and moving it to protect the position are opposite behaviours that look identical in a result column. Separate them and you can count them. "Times you checked the chart" sounds soft until you sort by it and see which trades you managed and which you merely held.

And the exit reason matters more than the entry reason. Closing because the thesis broke is a different act from closing because the position made you uncomfortable on a Tuesday afternoon. If the sheet cannot tell those apart, it is not describing your trading.

A column exists to catch a mistake you actually make. That is the whole rule, and it cuts both ways.

Before you add a field, name the mistake. If you cannot name it in a sentence, the column is decoration. After twenty or thirty entries, apply the second test: sort the sheet by that column. If the ordering tells you nothing you would act on, retire the column. A journal with fifteen fields that you abandon in a fortnight is worth less than a journal with eight fields you still fill in six months from now.

Keep the spine. Date, instrument, direction, entry, exit, stop, size, result — that is the record, and you need it. The style-specific fields sit on top of the spine as diagnostics. The spine tells you what happened. The diagnostics tell you why it keeps happening.

One more thing about reading what you collect. A column, like a framework, cannot be judged on five or ten trades. Give it a sample before you decide it taught you nothing. Changing the sheet every fortnight is the same habit as changing the strategy every fortnight, wearing a tidier shirt.

All of this assumes you know which trader you are. Many people do not, and they default to the generic template precisely because they have never said out loud what kind of mistakes they make.

That is where the know-your-style tool in the member app fits. It works through a short profile and returns an archetype — the System Hopper, the News Trader, the Brand New Beginner and others — with that archetype's listed weaknesses, common mistakes and focus points. It is a description of behaviour, not a market call, and it does not tell you what to trade.

Use the list it gives you as the source of your diagnostic columns. If your profile is the System Hopper, whose common mistake is abandoning a strategy after five or ten trades, you need a column naming which framework each trade belongs to and a running count against it, because the stated focus is to trade one framework for 100 trades or more before judging it. If your profile is the News Trader, whose common mistake is entering into a spike before liquidity returns, you need a column for the minutes between the release and your fill, and a column recording whether you took the spike or the pullback. If your profile is the Brand New Beginner, the honest columns are demo or live, and which part of the framework the setup came from.

The tool names a starting point, not a verdict. Styles change, and when yours changes the sheet changes with it. What should not change is the principle: the columns are chosen by the mistakes, and the mistakes are chosen by the style.

Trading carries risk of loss. Every decision you take is yours, and nothing on this page is financial advice.
