We can set up a FIX API but the reason it is limited to what we deem as institutional clients is because the volume needs to be substantial in order to warrant the setup 
 

Can you please have the client respond with the following information: 

1) What is your expected volume (in USD terms) per month? 

2) What instruments will be traded through the API? 

3) What are your leverage expectations? 

4) Will you be setting up the FIX connection yourself? If so, how many years of experience do you have trading via FIX?
