Grid Trader

Passive, structure-based liquidity strategy.

Best used when

price is range-bound or choppy
volatility is low to moderate
liquidity is decent
Hermes wants to harvest mean reversion inside a structure

Avoid when

trend is strong and persistent
event risk is high
liquidity is thin or chaotic
execution quality is poor

Core parameters

grid_levels: number of orders per side
grid_step_pct: spacing between levels
recenter_pct: when to rebuild the grid
volatility_timeframe: timeframe used for adaptive sizing
max_notional_per_order: per-order cap
fee_rate: fallback fee assumption

Hermes policy mapping

risk_posture adjusts grid spacing, levels, and recentering
priority adjusts aggressiveness and order cadence

Notes

The strategy does not decide regime fit itself.
Hermes decides activation.
Trader applies policy on reconcile.
report().supervision is descriptive, not imperative.
side_capacity and inventory_pressure describe the grid's current shape.
ordinary directional conditions alone should not force a rebuild or switch.
