Has anyone done Quant Trading on smaller exchanges?

Hi guys! I was wondering if anyone had an opinion on trading on smaller exchanges? For instance trading on regional exchanges in Europe, Asia etc…

My assumption is that there is less competition, easier to use basic quant strategy and more volatility.

What’s your thoughts?

If it makes sense, what are my option for brokerage? IBKR has access to smaller venues but not all of them. Do you know if there are alternatives for smaller API exchange?

Thank you 🙏
