ramseshk 03ebe9e795 Paper trader: 00 per strategy, match live node 8-strategy set
- Capital: 00,000 -> 00 (8 x 00)
- 12 old strategies -> 8 core strategies matching live node
- Asset distribution: 4 BTC + 4 ETH
- Removed Hawkes/DeepLOB/Cartea/Gueant/QueueImbalance imports
- Added Kalman Pairs signal generation
- All strategies share same signal logic as live node:
  BTC: OBI, Iceberg, Funding, A-S
  ETH: Pairs, Momentum, Mean Reversion, Kalman

"""
Paper trading engine — runs strategies against HYPERLIQUID MAINNET data.
Pulls real mainnet prices, orderbooks, and funding rates every second.
Executes all 7 strategies in simulation mode — tracks virtual positions,
computes PnL with realistic fees and slippage. No real orders.
Writes to /tmp/ftdt-paper-metrics.json for the dashboard.
