How the rules are applied:1. If any account is set as 'All transactions' then it will take precedence over all other accounts.2. There can only be one account set as 'This Currency' per currency, this rule will take precedence over the 'This Portfolio' rule.3. There can only be one account set as 'This Portfolio' per portfolio.
In case currencies dont match:When a new dividend is automatically added through the automatic dividends feature, if the default account uses a different currency than the dividend, then an appropriate exchange rate will be applied to the new Dividend.
