Outgoing API from Deutsche Bank Platform, and Gain GTX to MT4

My company is an NFA regulated introducing broker in the U.S. We currently work in the FX space.
I have FX managers that trade at several institutional brokerage shops, such as Deutsche Bank and Gain GTX. I also have retail investors with accounts hosted in Metatrader 4 at separate retail brokerage shops such as FXCM. 
My managers would prefer not to enter their trades in meta trader, but would prefer to execute their trades as they do at the shops they are already trading books of business.
I would like an API from the Deutsche Bank Autobahn FX Execution Platform and or the Gain GTX platform that could communicate to a Metatrader account at a separate brokerage shop. The signal does not need to be copied into several accounts... only one master meta trader account.

These platforms already have API's that are available to connect into these platforms. What I need is an outgoing API...

The Latency of the signal is obviously an issue. Hypothetically if it would be faster both the Deutsche bank platform and the MT4 platform could be hosted on the same computer. The signal would not necessarily need to be sent across the internet into a separate brokerage shop from the DB platform. I just need the two platforms hosted on the same computer to sync.  This seems like for my needs it my be a better solution than a "tradecopier" signal being sent to the broker

If you need further explanation or have a bid/solution feel free to contact me.

DB's platfrom https://autobahn.db.com/microSite/docs/autobahn_FX_brochure_sept2011.pdf

Gain's GTX platfrom http://www.gaingtx.com/technology.shtml

If you need it, I have relationship with these brokers and I might be able to get my hands on their internal development documentation.

Thanks
