METARPC / DEVELOPER GUIDES

Trade copying.
Built with Python.

From your first authenticated request to a monitored master–follower workflow. Clear examples, explicit sizing and practical recovery.

Start building → Explore the API

TLS transport · Owner authentication · Demo-first validation

• 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 Python 3.10+. Install dependencies and run the read-only List example. Keep your key in MRPC_API_KEY.

import asyncio
import os
from pycopier import CopierService

async def main():
    service = CopierService("copy.mrpc.pro:443", os.environ["MRPC_API_KEY"])
    try:
        result = await service.list()
        if not result.ok:
            raise RuntimeError(result.error)
        for copier in result.copiers:
            print(copier.id, copier.paused)
    finally:
        await service.close()

if __name__ == "__main__":
    asyncio.run(main())

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.
