We have all proprietary software, so I am probably not the right person to ask; however I used to use Tradestation, a lot of problems loading all the symbols, can not follow the universe of strikes, lousy technical support, etc..
We use a combination of feeds, the best one for options is probably Hyperfeed, but very expensive, Real Tick is all right for an inexpensive alternative, just be careful, there option quotes hang up when a lot is going on, ILX is as good as Hyperfeed, just more expensive,
