Can I withdraw funds from my account once I've met the minimum deposit requirement?

IB's intent with respect to the minimum is for account holders to maintain at least USD 10,000, or equivalent, although it's understood and accepted that equity may fall below that level due to trading losses and/or fees. Account holders are not, however, allowed to fund an account at a level sufficient to meet the minimum threshold and subsequently withdraw funds in an effort to circumvent the minimum.
