CoinEx stands out for zero-fee spot trading on select pairs — a massive advantage for bot traders. But their native bots are basic. This guide shows you how to combine CoinEx's fee structure with 3Commas' automation for maximum edge.
Why CoinEx + 3Commas Is Powerful
Zero maker fees on BTC/USDT, ETH/USDT, and other major pairs means your grid bots keep 100% of profits instead of paying 0.1% per trade. Over hundreds of trades, that's thousands saved.| Fee Comparison | CoinEx | Binance | Savings on 1,000 trades |
|---|---|---|---|
| Maker fee | 0% | 0.1% | $100 per $1K traded |
| Taker fee | 0.05% | 0.1% | $50 per $1K traded |
For grid bots making hundreds of small trades, CoinEx's zero maker fees are a game-changer.

CoinEx-Specific Tips
Pair Selection
Stick to zero-fee pairs for grid bots. Check CoinEx's fee schedule — the zero-fee list changes but always includes BTC/USDT and ETH/USDT.
Liquidity
CoinEx has decent liquidity on top 20 pairs. Below that, spreads widen and slippage increases. Monitor your bot's fill prices.
API Stability
CoinEx API is stable but slightly slower than Binance. For high-frequency strategies, test latency first. For DCA and grid bots, it's fine.
Security Setup
The Verdict
CoinEx's zero maker fees make it ideal for grid bots. Pair it with 3Commas for professional automation and you're running one of the most cost-efficient bot setups possible.
