100 round-trip scalps a day, engineered around maker fees.

Micro-movement scalping is a fee game before it's a directional game. This playbook runs maker-first on Hyperliquid native pairs and HIP-3 equity markets, in the two windows where order books are actually deep enough to fade.

Maker-first, always

Taker fees (0.045–0.09%) on 200 fills eat the entire edge. Sit on the book; if you can't get filled, the trade wasn't there.

Two windows only

09:30–11:30 EST and Sun 18:00–21:00 EST. Outside those, the book thins and slippage silently doubles your fee drag.

Fixed-R exits

Hard TP/SL set on-chain at entry. 1:2 R:R minimum. No moving stops, no averaging down.

API-driven, not clicks

Use the Hyperliquid Python SDK for entries and OCO exits. 100 manual scalps produces fatigue errors that dwarf fee savings.

Volume → tier discount

$100k notional × 100 round-trips = $20M/day → Tier 1 within days. Blended fee falls ~50%, which is the difference between profitable and flat.

Kill switch

Daily drawdown cap at 2× expected loss (e.g. -$1,350 on the $10k book). Auto-flatten and stand down for the session.
