I contacted Tradovate. Here is the scoop.
1.) Their main office is in Columbus, Ohio and they also have an office in Chicago.
2.) Tradovate will work on iPad Gen4. Tradovate also offers a version for the Mac, iPad and iPhone. Once you sign up for the demo,
https://www.tradovate.com/trial/, you will be able to download any or all of them. When you trade say on the iPhone you can see your orders on the iPad. The are completely in sync.
3.) All your orders will be placed either directly with the exchange or if they are advanced orders like trailing stops, OCO, OSO, GTC, Time Released, they will be held on a server. This protects you in the event your computer loses internet or your turn it off. Your orders will still be working.
4.) They currently do not have recording/playback functionality. This functionality is part of of historical data, back testing module that will be released at a later date
5.) Their minimum subscription is one quarter. I am not sure where you are currently trading but the savings can be significant and you do not have to pay for any software.
6.) they have a browser version and a cloud version of their platform and number 3 above applies to both the browser or cloud version.
7.) you do have to pay exchange fees but i think it comes less than $1.30 per contract say for the ES. Their website list the exchange prices for different contracts.
I have not used their services but am seriousely thinking of giving it a shot. Their platform offers dom..charts..and the type of orders i use. That is basically all i need. As i generally don't use indicators i do not need piles of indicators but i think they offer some.
I especially like being able to use a pc or mac or ipad or iphone.
