Quantity is the number of shares referenced by the transaction. This will be zero for a “Watchlist” item, that is, a holding or stock that you have added into your portfolio to monitor performance, not because you own any shares of it.
Price is the cost to purchase each share, in the currency of the exchange on which the share is traded. In the case of cash deposits or withdrawals, this is just the amount of the transaction.
Fees are the commission or cost with executing the transaction with a broker.
In the FT portfolio tool, fees are all optional, so if left blank, we calculate this as zero.
