How the Track Record Is Sourced

This is a self-published record of one real account. The public curve comes from stored daily NAV values: CPAPI points can be provisional and later IBKR Flex daily closes can settle them. Imported executions are de-duplicated using broker execution IDs when available and a documented fallback key otherwise. This is not an independent audit or attestation.

1. 01

   Daily-close source: IBKR Flex

   The current portfolio snapshot is selected from cached IBKR-linked tiers. Separately, IBKR Flex daily summaries can settle or correct a provisional CPAPI NAV point in the historical series. The public route does not query IBKR directly on each request.

2. 02

   Execution key when available

   An imported trade with a broker execution ID receives the key EXEC|executionId|symbol|action. If no execution ID is present, the importer falls back to timestamp, symbol, side, quantity, price, and order reference. These keys reduce duplicate imports; they do not constitute external verification.

3. 03

   Cross-feed de-duplication

   Currency is excluded from the execution-ID key because CPAPI and Flex can represent the same listing in different currencies. Order references are stored separately and help group partial fills. Rows without an execution ID rely on the fallback key above.

4. 04

   Retained daily NAV history

   Daily NAV values are stored by date without a display cap. CPAPI rows are provisional and may be updated intraday; a later IBKR Flex close or operator override can replace that date. The code does not guarantee a gap-free series.
