You do not need to include those types of transactions.
Examples of Cash Flow transactions are…
- Any deposits into your account (e.g. 401k contributions, when you transfer money into any investment account)
- Any withdrawals you make from your account
You do not want to classify any transactions that are “internal” to the Account. Internal transactions include…
- Dividends (either automatic dividend reinvestment or cash dividends)
- Market change Transactions
- Fees
- etc.
The reason you don’t want to include these types of transactions is their effects are accounted for in the balance and will be reflected in overall returns.
