From afee3489cd5332abbc7505ff13668c0ea6bb15e4 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sun, 22 Feb 2026 16:18:04 +0100 Subject: [PATCH] feat(broker_gateway_service): wire cTrader client for live order routing Add optional cTrader broker integration behind `icmarkets` feature flag. When CTRADER_ENABLED=true with credentials, orders are routed to cTrader after DB persistence. Handlers for account state, positions, execution streaming, and cancellation all proxy through the live broker when connected.
