Suspend mode for programs

On top of the 1 way communication channel (manager can make announcements to his investors) which was previously suggested, introduce a "suspend" mode. It would work the following way. 

A manager wants to take a 2 week vacation away from his trading desk. He puts his program in "suspend" mode:
- all open trades need to be closed
- all withdrawal requests are immediately executed since the trades are closed. 

It prevents investors from the opportunity of being in another program while his funds aren't actively traded. It also gives the opportunity to a trader to go on vacation with his investors feeling antsy.
