From the developer:
NQuotes connects MetaTrader 4 forex platform and Microsoft.NET enabling development of automated trading programs ("expert advisors" and indicators) for MT4 with C#, Visual Studio tools and .NET libraries. You can inspect values, place breakpoints and inspect execution step by step. Have a nicer experience than "Print" debugging in pure MQL.
