Understanding Lots and Total Cost for Cost Basis Updates

Learn about tax lots, multiple transactions, and how total costs are calculated when entering cost basis information for your transferred securities.

What is a lot?

A lot is a record-keeping method that tracks the purchase date, sale date, cost basis, and quantity for each security in your portfolio, even when multiple trades occur in the same security.

A lot represents shares, contracts, or other units traded together in a single transaction.

How can I edit position cost basis?

UPDATE COST BASIS

If you bought all shares in one transaction:

If you bought shares through several transactions:

  1. Click 'Add Lot' for each transaction
  2. Enter quantity, Acquisition Date, Total Cost, and Currency

What is the total cost?

Total cost represents the complete cost basis of a transaction, including:

  • Corporate action adjustments

Example: 100 shares of ABC at $30/share plus $5 commission = $3,005 total cost
