# ================================
# NOTES FOR PRODUCTION
# ================================
# Before deploying to production:
#
# 1. Set DRY_RUN_MODE=true initially and monitor for 24+ hours
# 2. Verify profit calculations match expected values
# 3. Ensure circuit breaker triggers correctly
# 4. Test emergency stop mechanism
# 5. Set up monitoring/alerting
# 6. Start with minimal position sizes
# 7. Gradually increase limits after validating profitability
# 8. NEVER set ENABLE_EXECUTION=true without thorough testing
#
# Recommended deployment sequence:
# Day 1: DRY_RUN_MODE=true (monitor only)
# Day 2-3: If stable, test with ENABLE_EXECUTION=true but MAX_POSITION_SIZE=0.1 ETH
# Day 4-7: If profitable, increase to MAX_POSITION_SIZE=0.5 ETH
# Week 2+: If consistently profitable, gradually increase limits
