what the heck triggered that spike?

[genuise]

It's my service bitcoin-analytics.com.
and yes I had reprted those volume descripancies to clark before.

We on bitcoin-analytics.com get trading data from bitcoincharts.com and clark uses mtgox streamAPI so this possibly is the cause of differences. In general the difference is that clark's service shows double volume than ours at spikes. And at spikes it is clearly visible. But I guess it is not big deal cause it seams nobody really cares... Althought I think this is very important.

Who is right then?

[genuise]

Although we are working on implementing mtgox streamAPI interface, we currently plan to release only orderbook volume based on full orderbook state.

From this experience I must admit that it is not as easy as one could think. To make it stable and robust. And in case of trade stream this task needs to be made much more carefull because of tricky filtering of only those trades which are relevant to the chart as the same trade can appear twice in cases when trade involves automatic currency conversions (based on mtgox stream api docs).
And we yet did not feel like touching this area yet, thus relying on bitcoincharts  trade stream which is universal for all exchanges. And support for multiple exchanges is our priority.

Nevertheless we really apriciate Clark's work which is an excelent example of design and usability for us.

wrong - no more than 15K... check the data

i think he took 2 days and 12 hours time period.

so youre both right.

how do you guys figure it was just one buyer? That makes no sense whatsoever.

[DoomDumas]

few guess..

- second wave from cash transfert after WP news
- BitInstant article that Challenge Wiki
- a big intelligent investor
- start of a more volatile market due to the halving (I would not bet on it, neighter on a significant increase in volatility or price swing due to halving)

imo, halving may have an effect on the long term, due to less pressure downward from miner having less coin to sell..

Actually there is no way to tell it except when big trade is performed in 15 seconds interval or in several consequtive intervals. In latter case it is also a guess... Also there are very often trades rounded by 0,5K or 1K BTC. When this happens and you see big trade of 3.5K for example, you can be sure that is was one person order than several which coincided into 3.5K

and there it was, boom!

what happened?

Someone bought ~36K BTC. In one big bite. (More than 420000 USD worth.)

did you say....420?

I envy you who aren't dealing with 3 strike laws. In the mean time more moonshine and designers. Which if you haven't figured out yet is why some of, well most of my post are garbage junky slur.
Legalize soon for humanity!

Thanks. I had no idea. That does sound pretty bad.  

If true, it seems very likely that this behavior has, and will continue to,
wrongly influence people's investment decisions in the aftermath of major movements.

(And perhaps lead to bigger swings when swings first happen.)

I mean, imagine if the kitco had an intermittent and erroneous 2x volatility multiplier. Scandal.

Questions:

(1) How do you know it is not the other way around? (I have to ask.)
(2) Is bitcoin.clarkmoody.com the only service affected? In particular: Is btccharts.com reliable?

Hi, as I showed in clark's thread

and as also acknowledged one post after the error definitly is not on our side.

as for the btccharts I do not have any data yet.
Maybe someone who has can say something?

\....\The reason for price to rise is buyers out number sellers. \....\

THIS!

Not necessarily.

i think it's just the latest pump and dump.

...and that just now is how you do your classic MtG pump and dump for dollars, which we have seen on MtG from the earliest days.  

The B exchanges are a joke, because they all still follow MtG and its pumpNdump teams up and down. Pathetic!

Any price difference leads to arbitrage, which traders will quickly take advantage of and close the price gap.

Depends on what "quickly" means to you. We've been waiting for arbitrage since other exchanges started to appear, which is what - more than a year now? Instead, they all simply follow MtG rates worldwide like a bunch of zombies. 

To me, simply confirms and reconfirms that the B xchange rate to any currency has little to no foundation in real supply and demand. Rather, it is still set by MtG pump & dump artists, and perhaps even MtG trading against itself. When all the other xchanges worldwide simply follow that, there is no way to tell what's really happening...

I think it's one of the main reasons B is still considered a ponzi scam in the mainstream, and something not to take seriously.
