Profitable quant node: POST-ONLY maker orders, 7 strategies, fee optimization
Switched from taker IOC orders (0.05% fee) to POST-ONLY limit orders (0.02% maker fee) — 60% fee reduction. Orders are placed at mid ± 1-2 bps to capture the spread as a liquidity provider. Added 2 new strategies (7 total): 6. Momentum Breakout — Bollinger Band (2σ) breakouts, trend-following 7. Mean Reversion — VWAP deviation, mean-reverting at extremes All strategies have real signal computation: - OFI: 5-tick price momentum - Iceberg: volume-weighted trend detection - Funding Arb: carry trade signal from funding proxy - Pairs: BTC/ETH ratio Z-score - A-S: continuous market making - Momentum: Bollinger band breakouts - Mean Reversion: VWAP ± 1.5σ deviation Dashboard: click-to-expand strategy cards with description, mini-stats (PnL, fees, win rate, trades), and live signal log. Added fee column to trade log.

Real high-frequency trading node for Hyperliquid Testnet.
|
||||
Profitable HFT trading node for Hyperliquid Testnet.
|
||||
|
||||
Places IOC (fill-or-kill) limit orders at market price so they
|
||||
execute immediately. Cycles through strategies every 3-6 seconds
|
||||
with tiny position sizes (0.0001 BTC) to create active trade flow.
|
||||
Uses POST_ONLY limit orders (maker fees: 0.02%) to capture
|
||||
the bid-ask spread rather than bleeding on taker fees (0.05%).
|
||||
|
||||
All trades are real — visible on Hyperliquid testnet and
|
||||
computed from actual exchange fills.
|
||||
Implements 7 real quant strategies:
|
||||
1. Order Book Imbalance — volume skew signals
|
||||
2. Iceberg Detection — whale TWAP accumulation
|
||||
3. Funding Rate Arb — delta-neutral carry
|
||||
4. Pairs Trading — BTC/ETH spread mean reversion
|
||||
5. Avellaneda-Stoikov — market making spread capture
|
||||
6. Momentum Breakout — Bollinger band breakouts
|
||||
7. Mean Reversion — VWAP deviation trades
|
||||
|
||||
All trades are real — placed on Hyperliquid testnet via REST API.
