  • 01 · Connect with confidence

    Understand keys, account IDs and transport before sending a request.

    Authentication →

  • 02 · Control the lifecycle

    Start once, inspect state, pause and clean up your test.

    Copier lifecycle →

  • 03 · Make sizing explicit

    Choose lot, balance or equity sizing and account for broker constraints.

    Sizing and settings →

  • 04 · Diagnose the result

    Separate network success from management success and broker execution.

Your first successful request

Requires Ruby 3.1+ and Bundler. Install dependencies and run the read-only List example. Keep your key in MRPC_API_KEY.

require_relative '../lib/rubycopier'
service = RubyCopier::CopierService.new('copy.mrpc.pro:443', user_key: ENV.fetch('MRPC_API_KEY'))
# list raises on failure; [] means a successful response with no copiers.
service.list.each { |copier| puts "#{copier.id}: paused=#{copier.paused}" }

Watch a real demo failure and recovery

Copier troubleshooting video follows an oversized follower request from its broker rejection through a corrected demo opening and closing. It demonstrates the control-panel workflow; the lifecycle recipes, sizing guide and error guide explain how to apply the checks in this SDK.

Use disposable demo accounts first. Hosted service usage is paid; consult current pricing. A successful management response does not prove that a broker executed the copied trade.
