I think beside Bitfinex and Gate.io , other exchange that has feature to place sell limit and stop loss in single potition is ZB.com. This is new exchange but now already include top 10 exchange. They listed alot of potential coin to trade. I hope Binance as the biggest crypto exchange add this feature so trading will be more easy to make profit with less risk.
i prefer to trust biggest on market and beign estabilished on market for years
for above example my choice is bitfinex, its most versatile, allow everything i need and stop loss is very important
