Well, its definitely odd.. but is it important? It looks to be someone just fluffing the volume, possibly testing a HFT bot. No fees, so its not like there are repercussions to it like on USD exchanges.
It is important when the buys and sells doesn't match with the orderbook... Isn't it?
No, not really? I guess if you are a TA PRO who relies on volume as an indicator
I give a lot on volume on stamp chart... I don't see chinies exchanges as a price leader. Problem is that 70% of traders thinks chinies exchanges are reliable despite all this.
Well I dont think anyone disagrees that gauging the "real" volume by China is quite difficult. Thats why I rarely bother trying to compare it. I just think of them as equals (Huobi, Okcoin, Bitstamp, and Bitfinex) despite China having a lot more volume.
If I really want to compare, then I'd look at the orderbooks, copy it down, and compare it in future. For example, if there were 5k of bids to break 2100CNY, and 12 hours later its 4k, but there was 50k of volume... I'd consider it a lot closer to '10k real' volume than 50k. So that absurd 10k volume spike earlier? Well, its pretty much insignificant volume and can be ignored.
Likewise, if the price broke 2100CNY on 10k volume, then I'd say most of it was real.
You see this sort of activity a lot when volume dies down. The price is just as volatile with a tenth of the volume, presumably because there isnt so much "high frequency trading".
