Would it be possible to set up the option on T212 that when you sell a stock that’s in dollars, the money goes into its own separate fund of dollars, not incurring a fee, being set up as a default for dollar transactions.
That way you have an available fund of dollars that should not incur a fee when being used to purchase new or additions to existing dollar stocks.
Only when you do not have enough funds in the dollar fund, will it then use your primary fund to complete the purchase, will then incur the fees.
Setting these options via a default, so people can set once and ignore after.
Just a thought.
