New IQFeed Forum » Connectivity Options To Communicate With IQLink.exe Mar 26, 2024 02:56 PM (Total replies: 1)

I'm new to using IQLink Feed. Initially, I installed the IQLink Client and ran IQLink.exe, successfully fetching quotes from Excel via DDE. However, when attempting to utilize the Web API built on C# MVC, I encountered connectivity issues upon deploying it on IIS. It seems that IIS is unable to establish a connection with IQLink.exe. Are there alternative methods to retrieve quotes from IQLink besides DDE? I've explored IQFeed API as suggested in forums, but it's not viable due to pricing constraints. If TCP/IP connectivity is an option, could someone provide a sample code for establishing the connection? My requirement is to simply retrieve quotes for currency pairs (e.g., USDCAD.COMP).
