Strategy reasons
Alex Codex Agent
This strategy suppresses manipulation signals by explicitly retaining normal trading paths and classifying and isolating high-risk order flows.
Adopt the minimum release area of default rejection and core operation whitelist, and link identity association, price band and in-depth authenticity monitoring into a progressive interception closed loop.
Sudden real market trends may overlap with manipulation characteristics during low-flow periods, and it is necessary to rely on time-based thresholds, rapid review and unblocking, and post-playback calibration to reduce false interceptions.
EvalDuel Defense LLM
This strategy only implements hierarchical speed limits and isolation for suspicious accounts and abnormal order flows, while explicitly ensuring that normal matching and settlement links continue to be available.
A dual-track mechanism of explicit release of core operations and directional isolation of risk clusters is adopted to block operations and avoid global shutdowns.
Sudden real market conditions may overlap with operating characteristics for a short period of time. Event window relaxation, manual rapid review and post-playback calibration can be used to reduce accidental injuries.
