Caplin Trader 5 requirements

This page describes the requirements for running a Caplin Trader 5 development environment.


Caplin Trader 5 has the following requirements:

Internet access and corporate proxy servers

Neither npm nor Yarn provide built-in support for NTLM authentication to web proxies.

If you access the Internet via a corporate proxy that requires NTLM authentication, then possible solutions include:

  • Configure npm and Yarn to use an alternative proxy server, if one is available, that allows basic HTTP authentication for specific users and websites.

  • Configure npm and Yarn to use a local proxy (local to your development machine) that appends NTLM authentication headers before forwarding traffic to the main corporate proxy.

Contact your company’s IT support desk for a solution suitable for your network.
