Live node:
- Registered in STRATEGIES dict (8th strategy)
- Signal: KalmanPairsTrader.step(eth, btc) every compute_signals()
- Adaptive hedge ratio updates with every tick
Paper trader:
- Registered in STRATEGIES dict
- Signal: KalmanPairsTrader integrated into compute_signals()
- Falls back gracefully if kalman_pairs module not importable
Historical backtests:
- Ran for BTC, ETH, HYPE, VVV (4 files)
- kalman_pairs_{TICKER}_*.json in results/historical/
- Visible on dashboard under Historical tab (8 strategies x 4 coins)
Dashboard: now shows Kalman Pairs card on all three tabs.
Risk panel now shows below strategy grid: VaR 95%, CVaR 95%, Max DD,
Calmar ratio, Sharpe, Sortino. Strategy correlation summary with
color-coded ρ values (red=high >0.7, amber=medium). Auto-refreshes
when paper data updates (throttled 30s). Collapsible with ▶ toggle.
backtests/historical_runner.py: Fetches real 1h candles from Hyperliquid
mainnet API (candleSnapshot endpoint). Runs all 7 strategies against
actual BTC price history (721 candles, 30 days, $63,024→$63,605).
Each strategy's signal logic operates on real OHLCV data with
configurable fee tiers. Saves to backtests/results/historical/.
Results on 30d BTC data at VIP0:
Mean Reversion: +93.87% net (Sharpe 0.94)
Order Book Imbalance: +54.31% net (Sharpe 1.03)
Avellaneda-Stoikov: -1.02% net (Sharpe -0.13)
Iceberg Detection: -33.20% net
Momentum Breakout: -54.72% net
Server: Added /api/backtests/historical (list) and
/api/backtest/historical/{name} (full data) endpoints.
Dashboard: Added "Historical" tab with "Real Data" badge. Cards show
coin + mainnet source. Click opens the same detail panel with fee
tier dropdown and equity chart.
Backtest detail: openDetail() now fetches full backtest JSON from the API
instead of showing "Full trade data not in summary". Renders equity curve
chart + full trade history table with 100 rows.
Backtest reproducibility: replaced hash(key) with fixed per-strategy seeds.
Python's hash() is randomized per process (PYTHONHASHSEED), causing wildly
different results for same strategy across runs. Now deterministic.
Server: added total_trades and sortino to /api/backtests summary response.
Paper trader: fixed Avellaneda-Stoikov simulate using TAKER_FEE instead of
MAKER_FEE. Lowered OBI signal threshold from 5bps to 1.5bps for flat markets.
Live node: added None-guard in get_mark_prices — Hyperliquid testnet API
sometimes returns null, crashing the node. Wrapped in try/except.
Paper trader now tracks individual equity history per strategy
(strategy_equity dict with deque per strategy). Metrics file
exports per-strategy data for dashboard rendering.
Dashboard paper chart upgraded to 7 overlaid area series:
- Each strategy gets its own colored curve (green, blue, purple, etc.)
- 300px height for better visibility of multiple lines
- Color palette distinguishes strategies at a glance
$100K total capital: $10K per strategy × 7 + $30K reserve.
Exeria Charts evaluated: excellent library (Benzinga award winner,
Canvas/WebGL, exchange connectors) but requires npm+bundler —
not suitable for single-file dashboard. Lightweight-charts
remains the right choice for our architecture.
Tab IDs now match JavaScript: tab-backtest instead of tab-bt.
Paper trading increased to $100,000 ($10K per strategy, $30K reserve).
Server default paper metrics updated to $100K.
New paper trading engine (live/paper_trader.py):
- Pulls real mainnet prices, orderbooks, funding rates every 2s
- Runs all 7 strategies in simulation without placing orders
- Simulates fills at market with realistic taker fees (0.05%) and slip (1bp)
- Avellaneda-Stoikov: simulates spread capture with 15%/tick fill probability
- Tracks virtual positions and PnL per strategy
- $5,000 capital ($1,000 per strategy, $1,000 reserve)
- Writes to /tmp/ftdt-paper-metrics.json
Dashboard updated with 3 tabs:
- Live Trading (Testnet) — real orders on testnet
- Paper Trading (Mainnet) — simulated fills on real mainnet data
- Backtesting — 30-day simulated results
Server.py: added /ws/paper WebSocket endpoint, paper_clients set,
paper metrics reader and broadcast loop.
