Exchange can work with cold wallets. Only 0.01 Bitcoin and Litecoin equivalent are stored on the server (this option can be disabled).
When the established balance is reached, the script itself drops the excess into cold wallets. Wallets Bitcoin, Litecoin, from Fiat Perfect Money are connected.  

There is a robot that places orders for the remainder of its established balance, that is, it can work as an exchanger.

Have your own API.  

It is possible to install trial version on your server.
