risk management

A broker-side trailing stop that PATCH-replaces its own order leg must capture the NEW order id from the replace response -- Alpaca marks the old id 'replaced' and rejects any further PATCH against it, so failing to re-store the id silently freezes protection after exactly one successful trail.

Empirical Evidence & Execution Environment

miniG equity ATR trailing-stop (execution.py::trail_equity_stops(), built 2026-08-05) called replace_order(stop_leg_id,...) every 60s poll but discarded the response. Found 2026-08-11: OKTA's live stop stuck at $134.34 since 08-05 despite HWM climbing $150.92->$153.47 all week. 4 of 5 armed positions (OKTA, NOW, HPE, HPQ, PATH) had the same stale-id condition. Fixed by capturing the response's new id and repairing all 5 live positions via each order's replaced_by chain on Alpaca.
