{"term":{"slug":"what-is-trading-journal","term":"What Is a Trading Journal?","definition":"A systematic record of every trade including entry and exit details, the reasoning behind the trade, which rules were followed or violated, and outcome metrics. For prop firm traders, a trading journal is the primary tool for identifying behavioral patterns that cause rule violations and account failures.","extendedExplanation":"A trading journal does more than log trades -- it creates a feedback loop between decision and outcome. Without a journal, traders remember their wins vividly and minimize losses in hindsight (memory bias). With a journal, the data shows the unfiltered truth: which setups actually produce edge, how many rule violations correlate with losing days, and whether the emotional state at entry predicts outcome.\n\nFor prop firm traders specifically, journaling serves a critical compliance function. Each evaluation attempt ends in either a pass or a violation. Without a journal, failed attempts produce vague lessons (\"I was trading too aggressively\"). With a journal, the data shows exactly which rule was violated, on which trade type, and under what market conditions. This transforms random account failures into structured learning that reduces the next evaluation fee cost.\n\nEffective prop firm journals capture: trade setup category (the specific pattern or signal), market conditions at entry (trending/ranging/news event), rule compliance check (was this trade inside my daily loss budget?), emotional state at entry (clear/anxious/revenge mode), and post-trade review notes. Apps like Edgewonk, TraderSync, and TradesViz provide structured digital journals. Physical journals work equally well if maintained consistently.","exampleWithNumbers":"A trader fails 4 consecutive FTMO $100K evaluations (total cost: EUR 2,160 = ~$2,350). After the 4th failure, they start a trading journal. After 60 days of journaling, the data reveals: 78% of violations occurred on trades taken after 2:00 PM EST (when they were \"bored\" and forcing setups). Win rate on pre-noon trades: 62%. Win rate on post-2PM trades: 31%. Rule: no new entries after 1:30 PM. 5th evaluation: pass in 18 trading days. The journal identified the behavioral issue that 4 failures could not. Total cost to discover this rule: $2,350 in fees. Annual savings from not taking post-2PM trades: roughly $400 in expected evaluation fees averted.","category":"risk","relatedTerms":["key-metrics","win-rate","risk-per-trade","consistency-rule","evaluation-phase"]},"_links":{"self":"https://runvigil.app/api/glossary/what-is-trading-journal","page":"https://runvigil.app/learn/what-is-trading-journal","allTerms":"https://runvigil.app/api/glossary","learn":"https://runvigil.app/learn"}}
