It is worth adding this exchange real volume + a lot of liquidation

I was about to implement but I didn't find any public api exposing liquidation data on coinex ?
This greatly reduces the interest in adding that exchange back into aggr

Only this https://www.coinex.com/res/contract/order/finished/liquidation?market=BTCUSDT&page=1&limit=100 which is NOT going to be available on client side as it is protected by CORS (server side can still fetch those, even tho it's a pain in the ass to implement, I guess that's how coinglass do it ?)

But maybe I just didn't look deep enough into their documentation...
