How the Track Record Is Verified

“Verified” is a word that gets thrown around. Here it has a specific meaning: the published equity curve and every closed position are reconciled trade-by-trade against the founder's Interactive Brokers Flex statements — the same broker-generated records used for tax and audit. This is a single real account, disclosed retrospectively.

1. 01

   Official source of truth: IBKR Flex

   Positions and executions are matched against Interactive Brokers' official Flex statements — the same regulated brokerage records used for tax and audit. The curve reflects executed fills, not estimates or self-reported numbers.

2. 02

   Stable per-execution key

   Every trade is keyed with the fields EXEC, brokerExecutionId, symbol, and action. The broker execution ID is globally unique, so the same fill is never counted twice even when it arrives via two different feeds (Activity Statement and TradeConfirm).

3. 03

   Cross-feed de-duplication

   Currency is deliberately NOT part of the key: CPAPI maps non-base listings to the account base currency (EUR) while Flex returns the instrument currency (USD). Including it would split one execution into two rows. Order references live in their own column and only group partial fills of the same order.

4. 04

   Append-only, gap-free NAV history

   Daily NAV points are written to an append-only equity-history table (no cap, no silent overwrite). A point is only rewritten under an explicit, logged decision — the series you download is the series that was recorded, in order.
