Trading process
A trading journal that can explain an execution mistake
At a glance
A useful journal preserves what was planned before the trade and what actually executed afterward. Keep timestamps, order settings, fills and costs, then classify discrepancies. A profitable result does not prove the process was correct.

“Good trade” is a poor diagnosis. A lucky price move can hide a wrong quantity, and a losing trade can follow the recorded plan exactly. A useful journal makes the sequence reconstructable without rewriting the original intention after the outcome.
Keep the before and after separate
CME's trade-log lesson encourages recording and reviewing decisions. The worksheet below is CoinFom's original execution-focused adaptation, not a tested method for improving returns.
| Before submitting | After execution |
|---|---|
| Asset, venue, product and timezone | Order ID and fill timestamps |
| Intended quantity and maximum exposure | Filled and still-open quantity |
| Limit, validity and trigger reference | Average fill price and final status |
| Planned invalidation or exit condition | Actual exit instruction and fills |
| Fee assumptions and other costs | Actual fees, funding and credited rebates |
Keep credentials and recovery phrases out of the journal. If screenshots include account identifiers, store them privately rather than publishing the raw files.
Reconstruct a small mistake
Suppose the plan was to buy four fictional units, but the submitted quantity was five. Later, all five sell at a profit of 1 USDT per unit before costs. The gross result is positive 5 USDT, yet actual quantity exceeded the plan by (5 − 4)/4 = 25%.
Calling it successful solely because it made money hides the input error. Conversely, correcting that process does not guarantee future profits. Record the discrepancy as quantity entry, preserve the evidence and choose a concrete review step, such as checking quantity against the written plan before submission.
Make the cost column auditable
Do not mix estimated cashback with confirmed credits or subtract fees twice from a net result. Bybit's P&L FAQ illustrates why the platform's field definitions matter. Link the journal entry to actual statement rows rather than relying on a rounded screenshot total.
Use one consistent sign convention: payments reduce the result, receipts increase it. Keep transfers between your accounts separate from trading P&L. If a cost is missing, mark it unknown instead of silently entering zero.
Review patterns without inventing statistics
After several entries, group issues by quantity, order type, timing, unfilled remainder and data interpretation. Count only the records actually reviewed and state the sample period. Ten entries cannot establish a reliable lifetime win rate, and a journal is not a substitute for a controlled strategy test.
For a worked ledger example, see reconciling profit and fees. The aim is a traceable account of decisions and execution, not a polished story about the result.
