If you run a grid bot or any automated strategy, you've optimized the spacing, the range, the rebalance logic. But the fee side often goes unexamined — and on a high-churn bot it can quietly eat 20-30% of your gross returns. Here's the checklist I use.
1. Know your effective fee, not the headline
The exchange shows 0.02% maker / 0.05% taker on futures. Your real cost is the blend:
effective_fee = maker_share * maker_fee + (1 - maker_share) * taker_fee
Most bot operators assume they're mostly maker. Verify it. If your grid uses post-only orders you should be 90%+ maker. If you cross the spread to guarantee fills, you're paying taker on those, and it adds up fast.
2. Three levers that cut the effective fee
- Maker share — switch limit orders to post-only (rejected if it would take, so you never accidentally pay taker).
- VIP tier — your 30-day volume already discounts your base fee; concentrate volume on one venue to climb faster.
- Fee rebate — a referral / sub-broker channel passes back a percentage of the fee you pay. It stacks on top of the VIP tier and token discount (BNB / OKB); it does not replace them.
3. The rebate is the most-overlooked lever
The standard referral code caps the rebate at ~20%. A sub-broker channel pushes it toward 40%. For a bot doing $5M/month that's a few hundred dollars a month back — pure margin, no strategy change.
