Exposure Protector
Defensive rebalancer that trims skew and protects exposure.
Best used when
- one side of the book dominates the account
- Hermes wants to reduce imbalance
- the market is still tradable, but caution is needed
- controlled rebalancing is more important than new alpha
Avoid when
- the market is thin or chaotic
- the venue is unstable
- Hermes wants a pure entry strategy
- frequent churn would be too expensive
Core parameters
trail_distance_pct: distance from price for execution
rebalance_target_ratio: desired base/value balance
rebalance_step_ratio: how much to move per action
min_rebalance_seconds: minimum time between actions
min_price_move_pct: minimum move before a new action
Hermes policy mapping
risk_posture controls caution vs aggression
priority controls urgency and cadence
Notes
- This strategy is passive until Hermes enables it.
- It should protect and rebalance, not decide regime.
- Trader derives concrete execution values from policy.
