Support Board

I'm investigating a new platform, and I have some questions:

1) do you support continuous futures contracts, i.e., so I don't have to roll them manually? (I use Interactive Brokers).
2) Do you support futures spreads, meaning can I pull those up on a chart?
3) Does your platform support the ability to write my own indicators?
4) Does your platform support multiple brokers? i.e., so I could trade futures from say Amp and stocks from Interactive Brokers?
5) Do you have a scanner window, so I can scan multiple stocks/futures at once for specific criteria and get an alert when triggered on the scan?

Thanks.
