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
min_order_notional_quote: minimum quote notional for one action
max_order_notional_quote: optional quote notional cap for one 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.
report().supervision should be interpreted as a defensive attachment signal, not as a preferred replacement for a healthy grid during persistent trend continuation unless imbalance is genuinely severe.
live fee rates are used directly, and quote notional is the canonical sizing unit.
