# 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
