Execution Modes

Mode	Purpose	Usage
DRY_RUN	Logging only, no orders placed	Testing, debugging
DEMO	Paper trading at live prices	Testing signals, validating strategy
LIVE	Real money on Polymarket	Production trading (after validation)

Quick Start (Demo Mode)

1. Update Configuration

Add to .env or .env.local:

# Execution settings
EXECUTION_MODE=demo              # DRY_RUN, DEMO, or LIVE
DEFAULT_POSITION_SIZE_USD=100    # Demo position sizing
MAX_POSITION_SIZE_USD=5000       # Hard limit per trade
MAX_DAILY_LOSS_USD=1000          # Stop loss for the day
MAX_DAILY_VOLUME_USD=10000       # Max daily trading volume
MAX_CONCURRENT_POSITIONS=10      # Max open positions

2. Install Dependencies

Requirements already added in Phase 1. Just verify:

pip install sqlalchemy asyncpg

3. Create Phase 2 Tables

PostgreSQL will auto-create on first run:

# When you start the bot with Phase 2 enabled, tables are created automatically
# OR manually initialize:
python -c "
import asyncio
from polytracker.db_pg import AsyncDatabase
from polytracker.models_execution import Base

async def init():
    db = AsyncDatabase()
    await db.connect()
    # Tables created automatically via SQLAlchemy
    await db.disconnect()

asyncio.run(init())
"

4. Enable Execution in Main Bot

Edit polytracker/main.py to wire in Phase 2 (shown in PHASE_2_INTEGRATION.md).

5. Run in Demo Mode

export EXECUTION_MODE=demo
export DEFAULT_POSITION_SIZE_USD=100
export TELEGRAM_BOT_TOKEN="your_token"
export TELEGRAM_CHANNEL_ID="your_channel"

python -m polytracker.main

Bot will now:

Detect whale signals
Execute paper trades at live Polymarket prices
Track P&L in demo
Send Telegram alerts
Log execution statistics

Database Schema (Phase 2)

Orders Table

Tracks all trade orders:

id — Order ID (primary key)
order_id — Polymarket order ID (after placement)
wallet_address — Whale wallet address
market_id, market_slug, market_title — Market details
direction — YES or NO
size_usd — Position size
entry_price, avg_fill_price — Execution prices
status — PENDING, PLACED, FILLED, CANCELLED, FAILED
execution_mode — DRY_RUN, DEMO, or LIVE
created_at, filled_at, closed_at — Timestamps
pnl, roi_pct — Profit/loss when resolved
error_message — Failure reason (if applicable)

Positions Table

Open trading positions:

id — Position ID
order_id — Links to order (FK)
wallet_address — Trader
market_id — Market
direction — Original entry direction
size_usd, entry_price, entry_timestamp
current_price, unrealized_pnl — Live P&L
is_closed — Position status
realized_pnl, realized_roi_pct — Final P&L when closed

Risk Events Table

Risk management event log:

Tracks every risk check (passed or blocked)
Why orders were rejected
What limits were breached
Actions taken (cancelled, blocked, etc.)

Execution Stats Table

Daily execution summary:

Orders placed, filled, cancelled, failed
Daily P&L, win rate
Max concurrent positions
Risk events triggered

Configuration Options

Risk Limits (in config or .env)

# Position size
max_position_size_usd = 50000.0          # Max per order
default_position_size_usd = 1000.0       # Default scale for demo

# Daily limits
max_daily_loss_usd = 10000.0             # Stop loss
max_daily_volume_usd = 100000.0          # Max daily trading

# Position limits
max_concurrent_positions = 10            # Max open trades
position_max_age_hours = 72              # Auto-close after 72h

# Signal filtering (existing)
min_whale_win_rate = 0.60                # Only follow 60%+ win rate whales
min_market_liquidity_usd = 10000.0       # Liquid markets only

Logging & Monitoring

Console Output

Phase 2 execution logs show:

🐋 Processing signal: Should Bitcoin hit $100k? | YES | high_conviction | Strength: 0.95
  ✅ Risk check passed
  📊 Execution size: $250.00 (whale: $2,500.00, scaling: 10.00%)
  📋 Demo execution: fetching current price...
    Current price: $0.6234
    ✅ Demo filled: $250.00 @ $0.6234

Execution Statistics

Track stats with:

# In main bot (if integrated)
await orchestrator.get_execution_stats(hours=24)

# Output:
{
  'period_hours': 24,
  'orders_placed': 15,
  'orders_filled': 14,
  'total_pnl': 234.50,
  'winning_trades': 10,
  'losing_trades': 4,
  'win_rate': 0.714
}

Telegram Alerts (Phase 2+)

When orders execute (will be wired up in Phase 2 integration):

Order Placed ✅
Market: Should Bitcoin hit $100k?
Direction: YES
Size: $250
Entry: $0.624
Mode: DEMO

Testing & Validation

1. Dry Run (No Orders)

export EXECUTION_MODE=dry_run
python -m polytracker.main

Logs all signals but places zero actual orders. Perfect for testing signal detection.

2. Demo Mode (Paper Trading)

export EXECUTION_MODE=demo
python -m polytracker.main

Places paper orders at live Polymarket prices. Watch P&L without real money risk.

Demo validation steps:

Run 2-4 hours, capture 5-10 demo signals
Check that orders fill at reasonable prices
Review demo P&L (should trend positive if signals are good)
Verify risk checks are working (blocks exceed limits)
Check Telegram alerts format

3. Live Mode (Real Money)

Only after demo validation and Phase 1 signal quality confirmed:

export EXECUTION_MODE=live
export MAX_POSITION_SIZE_USD=1000         # Start small
export DEFAULT_POSITION_SIZE_USD=500
python -m polytracker.main

Before going live:

Phase 1 signals validated (win rate >60%)
Demo mode tested (2-7 days minimum)
Risk limits configured appropriately
Telegram alerts working
Team aware of live trading
Start with small position sizes
Monitor first 24 hours closely

Position Sizing Strategy

Demo/Live position sizes scale whale positions:

Alert Type	Execution Mode	Scale Factor
Standard	DRY_RUN	0% (no orders)
Standard	DEMO	10% of whale
Standard	LIVE	25% of whale
High Conviction	DRY_RUN	0% (no orders)
High Conviction	DEMO	25% of whale
High Conviction	LIVE	50% of whale

Examples:

Whale buys $5,000 YES (standard alert) → We buy $500 (DEMO) or $1,250 (LIVE)
Whale buys $2,000 YES (high conviction) → We buy $500 (DEMO) or $1,000 (LIVE)

Risk Management in Action

Example: Daily loss limit = $1,000

Trade sequence:

Order 1: Lose $400 → OK, total: -$400
Order 2: Lose $300 → OK, total: -$700
Order 3: Requested $500 → BLOCKED (would exceed $1,000 daily limit)
- Result: "Daily loss $700 exceeds limit $1,000" (shown as $1,200 if we placed it)

Risk event recorded:

Risk Event [warning] daily_loss_exceeded:
  Daily loss $700 exceeds limit $1,000
  Action: blocked new order

Next Steps

Validate Phase 1 signals (in progress by you)
Configure execution settings (.env or config)
Run Demo Mode (2-7 days, watch P&L)
Review P&L, risk events, alerts
Adjust thresholds based on demo results
Graduate to Live (if validated and confident)

Debugging

Check Execution Status

# In a test script
import asyncio
from polytracker.db_pg import AsyncDatabase
from polytracker.execution.orchestrator import TradeOrchestrator
from polytracker.execution.executor import ExecutionMode
from polytracker.config import get_config

async def test():
    config = get_config()
    db = AsyncDatabase()
    await db.connect()
    
    orchestrator = TradeOrchestrator(config, db, ExecutionMode.DEMO)
    stats = await orchestrator.get_execution_stats(hours=24)
    print(f"Stats: {stats}")
    
    await db.disconnect()

asyncio.run(test())

View Order History

-- Connect to PostgreSQL
psql -h localhost -U polytracker -d polytracker

-- List all orders
SELECT id, market_title, direction, size_usd, status, execution_mode, created_at 
FROM orders 
ORDER BY created_at DESC 
LIMIT 20;

-- Check risk events
SELECT * FROM risk_events ORDER BY timestamp DESC LIMIT 10;

Known Limitations (Phase 2 MVP)

No order updates (orders placed but status not monitored)
Position tracking is basic (not synced with blockchain)
P&L calculation simplified (binary outcomes)
No stop-loss orders (manual close only)
No partial fills handling
Alert system not fully integrated

These will be refined in Phase 3 (hardening).

Phase 2 Status: ✅ Complete & Ready for Demo Testing
Next Phase: Phase 3 — Hardening (integration tests, alert tuning, logging refinement)
Telegram Bot: @mcinerney_bot

Ready to execute. Start with demo mode!
