Hi All,

I am somewhat new to futures trading. There seems to be lack of resources available which explains the relationships between:

1. What are Platform data feed, external data feeds (IQFeeds, CQG etc), exchange data fees, broker data, platform fee, esignal -->> how they all interlink each other and uses for each? I thought platform provided by the broker already has futures data, then what are all these IQfeed, Rithmic, CQG feeds (& then these guys also have platforms in AMP futures). Very confusing.

Any help in clearly and slowly demystifying the above would be very helpful.
