Trade copiers break at scale

Excel copiers and open-source plugins fail on partial fills, symbol suffix mismatches, and 500 followers hitting rate limits. Liability grows when copies drift from master P&L.

  • ×Fixed lot copy ignores follower equity differences.
  • ×Delayed copies chase price—followers enter worse fills.
  • ×No pause when master spikes drawdown beyond follower tolerance.
  • ×Missing audit log for regulatory or dispute resolution.

Enterprise copy trading architecture

Event-driven master feed, follower workers with isolated queues, configurable scaling modes, and reconciliation dashboards.

  • Proportional, fixed lot, and risk-parity scaling modes.
  • Max slippage and max delay rejects protect followers.
  • White-label admin for KYC tiers and performance fees.
  • API hooks for CRM and payment providers.
