Title: Large volume on Bitstamp without Bid/Ask walls being much effected? Post by: MatTheCat on January 31, 2014, 05:08:28 PM As can be seen from this screenshot:
http://imageshack.com/a/img837/7771/8alh.png A rather large buy order got triggered at around 808 on Bitstamp. However, neither the Bid or Ask walls were much affected by this 'trade'. anyone got any idea what is going on here? Title: Re: Large volume on Bitstamp without Bid/Ask walls being much effected? Post by: keithers on January 31, 2014, 05:23:19 PM Once that buy order was filled, the remaining bid/ask prices remained the same. That would happen every time unless it cleared off the sell wall, or there was a bid above 808

That would happen every time unless it cleared off the sell wall, or there was a bid above 808 No. I was sitting watching this as it happened. For a big like that to go through on the exchange in the normal manner, it would either have to bite a big chunk away from the Bid or Ask walls. This didn't. It was as though a large buyer and seller magically approached the market at the same time and met each others demands to the tune of 800 BTC. Bid/Ask depth remained constant throughout. Yet more fishy dodgy shite from exchanges that I really have trouble feeling that I can trust. Title: Re: Large volume on Bitstamp without Bid/Ask walls being much effected?

Bid/Ask depth remained constant throughout. I have also seen suspicious trades occur way off the mean like your chart shows a few price spikes, yet the volume in the order book seems unchanged. It seems the only way for this to happen is for a coordinated buy/sell with someone in control of both accounts. I have seen some exchanges (btc-e) report trades out of order (based on time stamp) and sometimes several minutes later. I have not tried to track their order book vs. trades to see what gets filled and if it looks real. There could also be a significant delay in the book depth as well. The thing that is most suspicious about these events is the price seems unaffected. If the book depth was truly eaten into then the price should rise at some point even if it is delayed.

If you look at the prices on bitcoinwisdom, the prices are sometimes different than on the exchange itself. Coinbase is like this frequently. Bitcoinwisdom will say that the price at coinbase is a certain dollar amount, but then if you are logged into coinbase, then the price is different. |
