MtGox BTC Price Excursion Starting 2013-06-21T07:05:49 UTC?

[jabowery]

I've got a program monitoring MtGox and it picked up a price excursion that was way out of the ordinary from 2013-06-21T07:01:32 until 2013-06-21T07:06:04 UTC.  I mean like an order of magnitude excursion.

I have to presume I have a bug in my program but if so it is so intermittent that it happens only once in a few weeks because that's how long I've been monitoring the streaming data out of MtGox and nothing like this has happened before.

PS:  I sure wish they'd include basic stuff like checksums and sequence numbers on their streaming interface.

Perhaps you can elaborate on what you exactly found.

Exactly?  Well I don't have the raw data from the mtgox stream for that time period if that's what you mean.

What I saw was the bid price go:

2013-06-21T07:01:32 $113.17302
2013-06-21T07:05:52 $2857.14285714286
2013-06-21T07:05:56 $6666.66666666667
2013-06-21T07:05:58 $12500
2013-06-21T07:06:04 $50000
2013-06-21T07:15:27 $113.01001

The main reason I'm not certain this is a bug in my code is that MtGox had just announced they were suspending withdrawal of USD.  DId someone panic over the temporary suspension of USD and decide to convert a huge holding to BTC so they could get money out of MtGox to somewhere they could access it?

It happened again today -- unfortunately before I got around to adding total logging of the MtGox data stream:


2013-06-22T12:57:31 $107.76001
2013-06-22T13:07:44 $10000
2013-06-22T13:19:42 $107.53001
