Is there some API available to try out your brokerage services? I would like to do some L2 market data analysis, and place some execution trades at your platform.
I would prefer to start from low-latency APIs since it involves trading. Either something similar to IB-API (C++), or FIX gateways would be fine.
Can you also share with me the costs involved to setup such a brokerage account for this type of connectivity?
