Net flow
Shows how much money was added to the account minus how much was taken out.
Net flow is the owner's money movement: deposits and similar funding minus withdrawals. It is like topping up or taking cash from a wallet. The wallet size changes, but that movement is not trading profit.
This metric helps separate account performance from capital changes. If the balance grew after a deposit, net flow shows that part clearly, so the trading result is not confused with money that was simply added.
Positive net flow means more money came in than went out. Negative net flow means more was taken out than added. Zero can mean no flows, or deposits and withdrawals that offset each other. A common mistake is to read a deposit as return or a withdrawal as a trading loss.
Example: the owner deposits $5,000, later withdraws $1,500, and receives a $100 broker credit. Net flow is $5,000 - $1,500 + $100 = +$3,600. That $3,600 explains capital movement, not profit from trades.
How we compute it
Flows come from account cash movements: deposits, withdrawals, broker credits and, for Exante/IBKR investment accounts, transfers or funding converted into the account currency. In TWR they become capital-flow events and are separated from strategy performance.
