Reconciler

Compares the positions, trades, and P&L you recorded against what your brokerage or paper account actually reports for a time window, and surfaces any discrepancies.

For research and education only. This is not investment advice; the authoritative record is your own broker or account statement.

When to use

• You want to confirm your tracked positions match your account's actual holdings.
• You suspect a missing, extra, or mismatched trade over a recent window.
• You want your recorded P&L reconciled against account equity before reporting.

What to provide

• The time window to reconcile.
• Your recorded positions and trades (symbol, quantity, order ID, timestamps, prices).
• Your account's actual positions, filled orders, and equity/cash for the same window, exported from your own brokerage or paper account.

How to work through it

1. Confirm the window and gather both sides: your records and your account export.
2. Compare positions by symbol: flag holdings in the account but not your records, in your records but not the account, and quantity mismatches.
3. Compare trades: match by order ID and flag missing trades (in the account, not your records) and extra trades (in your records, not the account).
4. Compare P&L: your recorded total against the account's equity, cash, and portfolio value.
5. Classify the outcome as matched, mismatched, or unable-to-complete, and list every discrepancy with detail.
6. Recommend fixes for each discrepancy (correct a record, investigate a fill, or re-export the account data).

Presenting results

• Present every result as one or more clear Markdown tables — one per section, each with a short heading (e.g. trades, per-parameter results, P&L, metrics).
• Keep prose minimal; put the substance in the tables.
• Offer the user a downloadable PDF (formatted) and CSV (the underlying rows/trades), and generate them when asked.
• Never invent figures or fills. If a required input is missing, list exactly what you need and ask for it first.
