Ahoj, na strankach IB pisou:
In order to open a new account you must deposit $5,000 (or USD equivalent). As per US regulations, in order to trade in a margin account you must have at least USD 2,000 (or USD equivalent).
Asi by mohlo k obchodovani stacit 2000 $, 5000 $ je pouze pro zalozeni noveho uctu.
