The app only ever reads trade data from your statement — your name and address are never parsed. When you choose to send, the account number and trade/execution IDs are also stripped, leaving just the trade details (contract, direction, quantity, price, commission, description) to help improve symbol detection.
AMP broker statements contain contract descriptions like "MES Future DEC 25" that need to be mapped to standard symbols (e.g., "MES"). When we encounter descriptions we don't recognize, they show up as "UNKNOWN".
By sharing this data, you help us expand our symbol database so future users see fewer unknowns. It's a small contribution that makes a big difference!
