In my younger days of trying to be a more active investor I moved money around a few times within my IRA, which makes the transaction history quite confusing. For instance, moving money from an index fund into an individual stock involved "exchanging" money into a money market fund and then "buying" the individual stock, so if I just look at the "buys" in the transaction history, that money would be counted twice - once when I originally bought the index fund, and again when I bought the individual stock.
