Define what is being observed
A curve can represent a backtest, demo account, live account or selected transactions. Establish that distinction before reading the result. Record the period, instruments, open positions and calculation method. A screenshot alone cannot reconstruct the series.
Look for gaps
Reconcile operations with a dated statement. Ask how cancellations, costs, corrections and discontinued accounts are treated. Results selected afterwards do not describe every scenario encountered. Useful evidence also identifies inactive periods and incidents without turning missing observations into invented zeroes.
Read COF evidence within its scope
The COF evidence page is a reference point, not a performance guarantee. Read each item’s source type, date and limitations. Unavailable evidence remains unverified. Documented past performance cannot predict the results of your own account.
Reconstruct a complete sequence
An isolated screenshot may show an outcome without the preceding decision, costs, missing events or period end. A more useful reading looks for a dated sequence and explicit scope: source or replicated account, simulation or live, full history or excerpt.
Keep interruptions visible. A history limited to favourable episodes cannot establish service coverage. Missing data does not become a loss-free operation, and a missing row does not prove there was no activity.
Classify evidence before interpreting it
Label the observation type, period and limitations. Readers should be able to find the source and understand what remains outside the file. A verifiable series is still historical; it is not a promise about future operations.
Your verification grid
| Item | Document or check to request |
|---|---|
| Scope | State live or simulated, source or copier, and the covered dates. |
| Completeness | Request losing trades, incidents and inactive periods too. |
| Account events | Separate market trades, deposits, withdrawals and corrections. |
| Charges | Identify what the history includes, excludes or leaves unknown. |
| Traceability | Link a claim to a dated statement while protecting private data. |
Practical questions
Is a curve screenshot enough to verify a history?
It shows an image at a point in time. Without scope, statements and method, it cannot reconstruct trades, external flows or charges. Evidence may be useful for one precise fact without establishing a complete history.
Does source history prove copying for every member?
No. Replication evidence requires reconciliation of the relevant account and its events in a private setting. The presence of a source or service does not prove every copy was executed.
