Help me to choose the right data provider Hi there, I am a programmer with background in math and stat. I have started to build an automated trading system. I already have sorted out the communication between servers and database and the next step is to choose the right data feed provider so that I can start having the live feed. I would like to be able to monitor up to 1000 share / store / equity. I would like to know which provider will be best in terms of: Execution speed, Data coverage, Ease of usage, and Commission charge. At the moment I am looking at Interactive broker, e-signal and open e cry. Of which I find IB has an entry barrier as it mentioned that registered account need to put down some money (about 3k USD) into the account on the spot. Your opinion is welcome.
