Trading Journal is an ongoing record of trading decisions and their outcomes linked to original supporting records. It allows the intended process to be compared with actual execution and rule compliance, costs and results to be assessed separately.
Trading Journal connects the original reason for a trade with what actually happened later. CME recommends recording reasons, price targets, time and entry or exit levels when entering a trade. Our editorial distinction: a profit table without the original conditions cannot establish whether a trade followed the plan. The record should separate information available at the decision from later commentary. An explanation added afterwards can be a useful reflection, but must not be presented as the reason held at the time. A journal is not proof that its author can predict prices. [1]
The CME worksheet separates the risk plan from results tracking and records opening and closing time, product, direction, size, entry, exit and notes for the result. Our journal design also preserves the order identifier and individual fill identifiers. A submitted or cancelled order is not automatically an executed trade. Partial execution requires recording the quantity actually traded and the remaining open position; intended size must not replace confirmed size. Time zones and units must be unambiguous so records can be matched. [2]
For securities trade confirmations, FINRA highlights price, quantity and fees or intermediary compensation. This US framework cannot be transferred to every Bitcoin service without verification. Our journal accounting principle is to state which costs the net result includes. A fee already included in a record must not be deducted twice. The valuation of an open position must be separated from the realized outcome of closed trades; an account deposit is not itself trading profit. A summary needs a common currency and a documented conversion method. [3]
Investor.gov recommends retaining and checking statements and trade confirmations because an intermediary might not keep records available forever. This source describes US securities, not a universal retention period for Bitcoin services or Czech taxes. Our working method is to reconcile the journal with exported fills, fees and account movements. A discrepancy is a reason to trace the supporting record, not silently overwrite an inconvenient number. A correction should preserve the original value, the reason for the change and its link to the document. [4]
CME emphasizes reviewing the reasons and course of trading afterwards, rather than only adding up results. Our own review framework therefore marks compliance with the plan in force at the time separately from profit or loss. A losing trade can follow the rules and a profitable one can break them. The compliance criterion must exist before assessment and refer to a specific plan version. An adherence flag does not confirm strategy quality; it only says the observed process matched the chosen rules. [1]
NFA warns that selecting a portion of historical results with hindsight can make their presentation misleading. Our methodological implication for a journal is to state the full observation period, the trade inclusion rule and each group's size. A favorable subset chosen after inspecting results is not an independent test. Differences between trades that followed the plan and those that broke it can also reflect other conditions. Without an appropriate comparison, they cannot establish that following the rule caused the profit difference. [5]
NFA explicitly distinguishes hypothetical results from actual trading and highlights hindsight, liquidity, slippage and behavior under real losses. Our journal design therefore separates confirmed trades, simulations and rejected opportunities. A rejection can record its reason and the data available, but a subsequent price move is not realized profit. A model result must be labelled and its assumptions stated; it must not be added to the account's actual result. Even a complete record does not remove uncertainty about the future. [5]
Investor.gov emphasizes keeping your own copies of trading documents and addressing errors promptly. Our organizational method adds separate retention of original exports and derived calculations, version labels and a verified backup. A repeat assessment must make it possible to establish how the summary was derived from its inputs. Recording an error should lead to a specific, verifiable corrective measure, not to rewriting past reasons. A personal trading journal does not itself replace required accounting or tax documents or professional assessment of those obligations. [4]
Profit and plan adherence are two different measures
For the clearest picture, read this entry together with Trading Plan, Expectancy, Max Drawdown, Slippage, Risk Management. The reverse links also lead from Trading Plan, Backtesting, Walk-forward Analysis, Paper Trading.
01Is it enough to record profit and loss?+
Not if we want to assess the decision process. We also need the conditions at the time, the plan version, actual fills and included costs. The outcome alone does not show whether rules were followed.
02Is the strategy that earned more in the journal better?+
A higher historical total alone is insufficient. Groups may differ in size, risk, period and selection method. A conclusion about a strategy's edge requires an appropriate comparison and consideration of uncertainty; the journal supplies records, not automatic proof.
