I don't think they would let you move more money then you have in 'available to withdraw' balance

No its not that. Its not the amount of money moved in on transaction. Its lile a net or gross. So you buy X stock for 100$. and then later you sell it for the same 100$ lets say you broke even. 
  
 200$ was transferred even though the account is only worth 100$.
