GSFX Investment, managed accounts service works with a system called PAMM (percent allocation management module). This means that your trading account is linked to their master account. Each time their master account executes a trade, your account will also execute a trade with a specific allocation of funds based on the size of your account. The investor still remains in full control of their account and will be the only person permitted to add or withdraw funds. Withdrawals from your trading account can be made when there are no open trades running. This means you can withdraw at any time when the market is closed over the weekend (provided all positions have been closed).
