Feature Request: OKex liquations

[joyser]

I think it would be awesome to have OKex liquidations showing up similar to Bitmex.

Unfortunately, it doesn't look like there is a socket for liquidations on OKex, just a http: endpoint which contains the data: Eg. Filled liquidations: https://www.okex.com/api/futures/v3/instruments/ETH-USD-190927/liquidation?status=1&from=0&limit=50 Unfilled liquidations: https://www.okex.com/api/futures/v3/instruments/ETH-USD-190927/liquidation?status=0&from=0&limit=50

Dope! I was looking for thoses. But as you pointed out it is http endpoint and okex does not have any Access-Control-Allow-Origin header set.

• My server wont like to serve okex liqs every 1 to 3 sec * every aggr.trade users, idk really but that seems unlikely. http://cors.aggr.trade do cache results anyway...
• Only way I could add that is by only allowing the calls for client that have a PROXY_URL =/= to mine (and i don't think anyone run their own instance atm lol)

I will implement it in the old version tho, just for fun 👍

Nice! And yeah, I think you're right, probably no one running their own instance! Maybe in future, if there was more demand, I could look at setting up a light weight node.js server to retrieve OKex liquidations, and serve them through a websocket to your app. What do you think? How many people do you think use your app at any one time?

It would work yeah, not a big fan of running a server just for that tho, and what if I want liquidations on LTCUSD, does the server track them as well ? idk Best solution would be to port aggr.trade into an electron app. C.O.R.S. free.

Another question, do you know what the "loss" part mean exactly ? From my understanding (and Im really not an expert) if a position get liquidated you lost everything yet https://www.okex.com/api/swap/v3/instruments/BTC-USD-SWAP/liquidation?status=1&from=1&limit=20 list all of them with 0 loss, I wonder why

[joyser]

That's a fair point.. I didn't think of the other coins.

The loss, as far as I know, is the margin the user attaches to the position. In fixed margin mode the user can attach 1BTC to a position without having to put everything they have in their account at risk. When their margin call price is reached, they will be liquidated and lose the 1BTC only. In cross margin mode the loss would be their whole account balance. The price, it seems to me, is the bankruptcy price. The margin call price (ie. the price the user gets liquidated) = bankruptcy price + minimum maintenance margin %. Note that the minimum maintenance margin is different depending on the size of the position, so the bigger the order the further you get liquidated from the bankruptcy price.
