Trading journal guides

A trading journal is a structured record of every trade you take. It exists so you can see your real edge through win rate, average win, average loss, profit factor and expectancy, instead of guessing from memory.

Expectancy is your average expected profit per trade. Formula: (Win% x Average Win) - (Loss% x Average Loss). Positive expectancy means the strategy makes money over a large sample.

Profit factor equals gross profit divided by gross loss. Above 1.0 is profitable, 1.5 is solid, 2.0+ is excellent. It measures how many dollars you make for every dollar you lose.

Export a trade history or account balance CSV from your broker, then drop the file into TradeStack's importer. The columns are auto-detected and mapped, duplicates are skipped, and your P&L calendar fills in instantly.

A genuinely free trading journal should include a daily P&L calendar, win rate, average win/loss, profit factor, expectancy, an equity curve and unlimited CSV import. TradeStack provides all of it free with no card and no trial countdown.

Log date, symbol, side, size, entry, exit, fees, realized P&L, setup tag and one note per trade. Per day, log total P&L, number of trades, and whether you followed your rules.

Max drawdown is the largest peak-to-trough decline in your equity curve, expressed as a percentage. A 50% drawdown needs a 100% gain to recover, which is why controlling drawdown matters more than chasing returns.

Track daily loss against the daily limit, running drawdown against the overall limit, and consistency of daily P&L. Most evaluations fail on risk rules, not on the profit target.

Tag each trading day with your mental state and rule adherence, then compare P&L across those tags. Revenge trading, FOMO and overtrading show up as measurable clusters of losses, not vague feelings.

Neither matters alone. What matters is that Win Rate x Avg Win exceeds Loss Rate x Avg Loss. A 1:2 R/R only needs a 34% win rate to break even; a 1:1 R/R needs 50%.

FINRA's old pattern day trader (PDT) rule required $25,000 in a margin account after four day trades in five business days. FINRA retired that rule on June 4, 2026 and replaced it with real-time intraday margin monitoring instead of a fixed trade-count and equity floor. Brokers have until October 2027 to fully roll out the change, so some firms may still apply the old $25k rule in the meantime.

Write the rules down first, replay historical charts bar by bar without looking ahead, log every trade the rules produce, then measure win rate, expectancy and drawdown over at least 100 trades.

Pick one market and one setup, define your risk per trade before your entries, trade small, log every single trade, and only increase size after 100 logged trades with positive expectancy.

Maximum adverse excursion is how far a trade went against you before it closed. Maximum favourable excursion is how far it went in your favour. Compare them across your winners and losers to place stops and targets on evidence instead of habit.

Size every trade so a full losing streak can't hit the daily loss or max drawdown, cap trades per day, stop after a set daily loss well inside the firm's limit, and let the profit target come slowly. Journal every evaluation trade so you know your numbers before you pay for the next one.

Export the report that lists individual fills or closed positions, not an account summary or balance report. Summary files only hold totals, so no journal can rebuild your trades from them.

Risk of ruin is the probability of losing enough to end the account. It rises with risk per trade and falls with positive expectancy. Cutting position size is the fastest way to lower it.
