Thin EA, Thick Server

How MyFXCopier keeps terminals lightweight while doing heavy lifting in the cloud.

Traditional copiers embed parsing, risk logic, and routing inside MetaTrader. That makes EAs brittle, hard to update, and expensive to support across brokers.

Our split

Layer Responsibility
EA agent License activation, heartbeat, inbox poll, trade execution
Cloud API Signal intake, normalization, delivery queue, risk checks

When a provider posts a signal, the server validates it, maps symbols per subscriber terminal, and queues a delivery. The EA only executes what the inbox returns — no Telegram parsing on chart.

Why it matters

  1. Faster fixes — change parsing rules without redeploying hundreds of EAs.
  2. Consistent risk — lot sizing and filters apply centrally per copy setting.
  3. Observability — every delivery and execution is logged for support and analytics.
