What a trading journal is actually for
2 min readUpdated
Why recording your reasoning and your discipline matters more than recording your P&L.
Your broker already records what you traded and what it made. That is the part you do not need help with. What no broker records is why you took the trade, what you had decided in advance, and whether you actually followed it — and that is the part that determines whether next month looks like last month.
The idea behind this app is the one athletes call reviewing the film: you cannot improve a performance you only remember in summary. A journal turns a season of vague impressions into something you can actually look at.
The three things worth recording
- Rationale — what you saw, and what made it a trade rather than a chart you liked. Written before the outcome is known, this is the only honest record of your reasoning.
- Discipline — whether you broke a rule, and which one. A profitable trade that broke your rules is not a win; it is a habit forming.
- Strategy — which setup this was, so you can eventually compare setups against each other rather than judging them all as one blended account.
Why P&L alone misleads
Over a small number of trades, results are mostly noise. A good process can lose for weeks and a reckless one can win for weeks, and if P&L is your only feedback you will learn the wrong lesson from both. Recording the process gives you something to evaluate that is not at the mercy of the last ten outcomes.
This is also why the app computes R-multiples, expectancy, and profit factor rather than only totals — they describe the shape of your trading, not just its balance.
What this app deliberately does not do
There is no AI coach, no trade replay, and no automatic broker sync. Those either replace the thinking that makes journaling work, or promise a connection to your account that this app does not want. You import or log your trades, and you do the reviewing. See the full feature list.
