How to Build and Use a Trading Journal
Create a journal that measures setup quality, execution, risk and costs instead of becoming a collection of unstructured notes.
A trading journal should answer specific questions: Which setups perform under which conditions? Are losses coming from the strategy or from execution errors? How much do costs change the result? A list of entries and exits is not enough. The journal needs a consistent structure, a review schedule and a small set of metrics connected to decisions you can actually improve.
What to record
For every trade, capture date and server time, instrument, direction, setup tag, market condition, entry, initial stop, target, position size and planned monetary risk. Add actual exit, gross and net result, commission, funding or swap, slippage and maximum favourable and adverse movement when available. Save before-and-after charts and mark whether the trade followed the checklist. Use neutral notes describing what happened rather than explanations written to defend the outcome.
Turn records into decisions
Review weekly for process errors and monthly for strategy patterns. Group trades by setup, session and market condition. Compare win rate, average win, average loss, expectancy, drawdown and rule-compliance rate. Avoid changing a strategy after a handful of trades; define a minimum sample beforehand. Choose one improvement for the next review period, such as reducing late entries or improving stop discipline, and measure whether it changes.
