Start with the trades you already made

Create your trading journal from your broker's history first, then add one short note for each trading day. That order matters more than which app or spreadsheet you pick.

New journals usually fail the same way. You design a sheet with thirty columns, type in every fill by hand and write an essay about each trade. It feels serious for four days. Then a busy afternoon comes, you skip one entry, and catching up feels like homework.

The fix is to make the boring part automatic and the human part short. Your fills, times and P&L already exist at your broker. The journal's job is what the broker can't record. That's what you were thinking, and whether you kept your rules.

Before you write a single note, load what you've already traded. A few months of history gives your first review something real to look at.

In Excel or Google Sheets, export a CSV from your broker. Keep one row per trade with date, symbol, side, size, entry, exit, fees and P&L. Add a formula column for win or loss. Resist adding more columns until you've used these for a month.

In Notion, build a database with the same fields as properties. Notion is good for notes and weak at math, so expect to do the sums elsewhere.

In a dedicated journal, connect your broker or upload the CSV. TraderLog imports from Schwab through its API and from IBKR through a Flex query. Whatever you use, check a few imported trades against your statement before you trust the totals.

Write one entry at the end of each trading day. Keep it to a few sentences. Per-trade essays are the habit that breaks first, so don't start there.

Two prompts are enough. Did I trade the way I meant to this morning? What's the one decision I'd change? If you didn't trade, write that too, along with why. A day you stood aside on purpose is worth recording.

Write before you look at your P&L for the day. Once you see a red number, the note turns into a story that explains the number. Written first, it records what you actually did.

Set a fixed time, such as ten minutes after the close. Same time, same place, every day. Missing one day is fine. Missing three in a row means the note is too long.

Thirty minutes at the end of week one. You're after one observation you can test next week.

After a month you have enough trades for patterns to start showing. Treat each one as a question to test. A handful of trades can make anything look like a pattern.

Look at behaviour as well as results. Do your losers stay open longer than your winners? Do you take a new trade within minutes of a loss? Does your size jump after a red trade? Do your afternoons give back what your mornings made?

You can dig these out of a spreadsheet with filters and some patience. A journal built for it does the counting from your executions. TraderLog's stats page also shows results after a win versus after a loss, and by hold time.

Pick the finding that costs you the most. Make one change for the next month and watch that single number.

Pick the one you'll still open on day twelve. That's a better test than any feature list.

A spreadsheet costs nothing and does exactly what you build. The price is your time: every fill typed or pasted, every formula maintained. It suits traders with a few trades a week.

Notion is pleasant for writing and linking notes. It's clumsy for statistics, and imports need manual work. It suits traders who care most about the written side. A dedicated journal imports your fills and does the math. You pay for that, so use the free trial on your real trades before deciding. Import a month, check the totals and see whether you'd open it daily.

Whichever you choose, the 30-day plan stays the same. History first, short notes daily, one weekly review.
