See page 36 on API PDF attached for Reuters data feed that needs to be available inside MT4 offline chart.
This should be working just like a standard chart in MT4
I understand that Metatrader 4 can use it's offline chart mode to import an external data feed.
I currently have access to a Reuters data feed..
If both historical data & Live data can be successfully used within MT4 Offline charting.. The project will then become completed :)
Look forward to be working with anyone that comes my way !
