Trading journals, drawdown, and strategy review
Record decisions and fills consistently, measure drawdown and recovery, and separate process errors from normal strategy variation.

A journal is useful when it preserves what was known and decided before the outcome. A collection of annotated winning charts is closer to a highlight reel. Keep original signals, rejected opportunities, execution records, and rule changes together.
Use fields that answer real questions
Record the timestamp and timezone, instrument, strategy version, market condition, trigger, planned entry, stop, target, size, and estimated costs. After execution, add actual fills, costs, exit reason, and realized result. Keep the original plan rather than overwriting it with what eventually happened.
A short process note can identify whether a trade followed the rule. Distinguish a valid losing trade from a rule violation that happened to make money. Otherwise, outcome alone can reinforce an unreliable process.
Measure drawdown consistently
Drawdown compares equity with its previous peak. If a hypothetical account falls from 10,000 to 8,000, the decline is 20%. Returning from 8,000 to 10,000 requires a 25% gain. Recovery percentages differ from loss percentages because the starting amount has changed.
State whether the equity series includes open positions, deposits, withdrawals, fees, and financing. An account curve that excludes unrealized losses can understate the risk of a strategy that holds losers open.
Avoid reacting to every small sample
A losing streak can occur under a strategy with positive expected value. It can also indicate that the strategy or execution has deteriorated. A predeclared review process is more useful than changing parameters after each loss.
Compare observed costs with assumptions, check data freshness, inspect rule compliance, and review performance by market condition. If you introduce a change, assign a new version and evaluate it separately. Combining all versions into one history can hide which rule actually produced the results.
Define pause conditions before stress
A risk plan can include maximum aggregate exposure, operational failure conditions, and review thresholds. The appropriate values depend on the situation; no universal daily loss limit fits every account or strategy. The essential requirement is that a threshold triggers a defined action rather than an improvised response.

A useful weekly journal review ends with a specific conclusion: the rules were followed, the data or execution failed, or a clearly stated hypothesis needs a new test. It does not need a new indicator every week.
