  - strategy: VIP Tier Advancement
    description: Increase CET balance, total assets, or trading volume to qualify for higher VIP tiers with lower fee rates.
    criteria:
      - CET token balance (including off-exchange)
      - Total asset value on CoinEx
      - 30-day spot trading volume
      - 30-day futures trading volume
  - strategy: Market Making
    description: Apply for Market Maker status to receive separate (potentially lower) fee schedules. Market maker level updates monthly on the 1st at 01:00 UTC.
  - strategy: Maker vs Taker Order Strategy
    description: Prefer limit orders (maker) over market orders (taker) to benefit from lower maker fee rates, especially significant at lower VIP tiers.

rate_limit_cost_implications:
  description: Hitting long-cycle rate limits triggers "low-speed mode," which can severely throttle trading throughput for up to 24 hours. Design API clients with rate limiting awareness to avoid unintended trading slowdowns.
  periods_at_risk: [1H, 4H, 8H, 24H]
  mitigation: Implement client-side request queuing and respect X-RateLimit-Remaining headers
