GLOBAL TRADER RANKINGS / RECORD COMPARISON
Benchmarks, Currency and Investment Mandates
Make relative-performance questions explicit before comparing heterogeneous traders.
A benchmark expresses a question
A benchmark is not a universal opponent for every trading approach. Its relevance depends on the mandate, investable universe, currency and observation interval. An equity portfolio, a leveraged currency account and a hypothetical signal sum need different context. Choosing the weakest benchmark after seeing the result can make a relative-performance claim look stronger without improving its evidence.
Freeze the benchmark and return convention before the comparison. Keep total-return and price-only series separate. A dividend-excluding price series cannot silently stand in for a reinvested investment return. If a matching benchmark source is unavailable, report that the relative result is not reconstructed.
Currency belongs to both numerator and baseline
A return expressed in one account currency can differ from the same assets measured in another currency. Currency conversion can also depend on the flow dates and valuation schedule. One current exchange rate does not reconstruct a historical investor's sequence of translated values.
The comparison tool treats mismatched currency labels as a compatibility gap. It performs no currency conversion and fetches no market prices. User-supplied matching labels only pass that metadata check; they do not establish that the records used the same conversion or hedging policy. Keep source definitions beside the labels.
Mandates change the economic comparison
A mandate can constrain concentration, leverage, shorting, liquidity and cash holdings. A trader pursuing absolute return has a different task from a long-only fund benchmarked to an index. Comparing cumulative percentages alone does not establish which manager better satisfied their stated objective.
Record the mandate as it applied during the observed period, not merely the current website description. Strategy changes can divide a history into different phases. A source-backed narrative may explain those phases without inventing a continuous factor profile or attributing every institutional result to one person.
Risk budgets and capacity require actual records
Exposure limits, available liquidity and investment capacity can affect the implementation of a strategy. A small contest account's reported percentage is not proof that an institutional allocation could obtain the same fills. Likewise, a large firm's capital figure is not itself a trading return or a personal wealth measure.
Do not infer capacity from fame or copy an undated capital estimate into a ranking formula. If implementation constraints are relevant, retain their original source and period. A qualitative description can be useful while still leaving capacity unknown. This publication does not estimate assets or economic risk for archived profiles.
Publish descriptive comparisons honestly
A reader may benefit from understanding that two approaches have different mandates rather than seeing them forced into one order. Use side-by-side fields for object, currency, dates, costs and benchmark. Identify which conclusions are sourced and which are editorial questions for further research.
The final statement should say what the benchmark comparison measures and what it does not. It cannot establish universal trading skill, guarantee future outperformance or certify subscriber execution. A well-defined descriptive comparison is more retrievable and more defensible than a global-best claim that collapses unrelated investment tasks.

Apply the distinction
Use the complete authored packet to inspect how this issue changes the permissible comparison. Record unresolved inputs rather than replacing them with a made-up number. Keep an original source reference beside each factual observation, and state when the calculation is illustrative rather than based on an actual account.
