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

### REPLY:
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$.

### END.
