i found this review :
So recently I created an account at chinese future exchange 796.com. I don't have any large amounts of Bitcoin there - I was only interested in future markets and wanted to give it a try.
It seems like they changed their API without any customer notice. A few days ago a ClosedBuy Order was the closure of a Long position (i.e. a sell order). Now it seems to be the closure of a Short position (i.e. a buy order).
http://imgur.com/C3pGH9ZI swear to god it was the other way around a few days back.
If I want to close my Long Position I still have to submit the close_buy request.
https://796.com/wiki/futures.html?type=weeklyfutures&api=close_buy2nd thing I noticed is that their API is giving weird net-assets & total-btc balance returns (+- ~4BTC jumps all the time in my case) even if i have no open order at all. Be careful!
