Why link a trade to an account
The link shows where the money for a buy came from and where the money from a sell went. It's optional: Strum calculates asset quantities and portfolio value without it.
You need the link if you want the cash balance in your portfolio to match your trades.
What "Update cash balance" does
- On. The balance of the selected account changes by the trade amount: a buy reduces it, a sell increases it.
- Off. The trade changes only the asset quantity. It doesn't touch cash.
Turn it off if you don't track cash in Strum.
"Cash balance is not affected" after import
This warning means Strum recognized the trade but couldn't link it to your account on its own. Choose the account manually: while reviewing the import, or later in Portfolios → Trades.
