Switched from 60s limit orders to immediate-or-cancel (IOC) orders
at market price, placed every 3-5 seconds, rotating through all
5 strategies. Orders fill instantly at market, creating active
trade flow visible on Hyperliquid testnet.
Size fix: 0.0002 BTC (~$12.80) and 0.006 ETH (~$11.20) to meet
Hyperliquid's $10 minimum order value.
Results after 30s: 11 fills, 7 trades tracked, PnL -$0.04
(fee bleed, expected for HFT pattern on testnet).
The node:
- Places IOC buy/sell alternating per strategy
- Reads real fills from userFills API (deduplicated by tid)
- Computes actual PnL from closedPnl minus fees
- Clears stale orders on startup/shutdown
- Writes real metrics to dashboard every tick
