Developing auto-trading with IG API (and NADEX)

Hello

I would like to connect my trading signals to a live account at IG.com (and Nadex on second phase) 

The script would grab my signals (we can discuss about the best way to do that) and would place a trading order at IG.com, using the API

signals can be fired anytime during the day, and it will include the current time, the asset name, the current price, the direction and the end time of this prediction.

IG API documentation can be found here    labs.gi.com

if this goes well, we will continue to NADEX, using their FIX api (The NADEX FIX api will be a different job)

Thanks 

Ben
