Samples :: Dynamic Acceptor

Dynamic Acceptor Sample

Description

This is a Dynamic FIX Acceptor that waits for incoming connection and accepting FIX session without a prior creation of session object.

Usage

  • Run the sample:
    • win: 1-DynamicAcceptor.bat
    • linux: 1-DynamicAcceptor.sh
  • Clean everything:
    • win: clean.bat
    • linux: clean.sh
