COST RECONCILIATION GUIDES

Start with the ledger problem you actually have

Original English guides built around field-level reconciliation and anonymized examples—not translations of the Chinese library.

What these guides assume

Each guide starts from an exported Binance or OKX perpetual futures ledger and works at the field level: which column answers which question, and which rows must not be double counted. They assume you have the export in front of you, not that you want a general explanation of futures.

How to pick one

If your realized P&L and your wallet balance disagree, start with the P&L reconciliation track. If you want to know what a month of trading actually cost, start with the cost accumulation track. Each guide ends with a five-item check you can run against your own file.

About the numbers

Every amount and rate is an anonymized example chosen to make a formula legible. None represents a real account or a current fee schedule. Your own rates depend on the venue's published schedule and your fee tier.
