Lang & Schwarz TradeCenter API

The goal of this project is to receive the live data from the Lang & Schwarz TradeCenter using the Lightstreamer Protocol.

The protocol

The client sends a request to /lightstreamer/create_session.js to create a session. The LS_adapter_set must be WALLSTREETONLINE and the LS_phase a random number.
The server will answer with a response that contains the session key.
Next, the client sends a request to open a websocket.
Using this socket, the client tries to bind the session, sending the bind_session command togehter with its LS_phase and the session key. However, instead of the response I get on the website, I receive the following content which probably means that someting went wrong: setPhase(<LS_phase>);retry();. Unfortunatly, I don't know why...

Any contribution to this project is welcome. Thanks!
