  • 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.

    Troubleshooting →

Your first successful request

Requires .NET SDK 8+. Install dependencies and run the read-only List example. Keep your key in MRPC_API_KEY.

using MetaRPC.Copier;
using var service = new CopierService("https://copy.mrpc.pro", Environment.GetEnvironmentVariable("MRPC_API_KEY") ?? "");
var result = await service.ListAsync();
if (!result.Ok) throw new Exception(result.Error);
foreach (var copier in result.Copiers) Console.WriteLine($"{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.
