UpstoxNet can be used to connect Excel, AmiBroker and Other COM supported windows applications to your trading a/c using API.
Simply put, you can fire orders, check position details and can do lot more from AmiBroker.

We have included sample AFLs in the zip file.
We plan to launch Excel/AFL library, which will host lot many trading systems coded in VBA/Excel.
