Ok yeah I see what you mean.
I'll try Bitstamp then, it's not really for the best to stay on a trading platform with such problems xD
It's not that I am vouching for Bitstamp either, considering the risks any and all trading platforms present. I am just talking about my personal experience/incidents or lack thereof.
Can you tell how many BTC were bought/sold in that huge spike to 2082€? According to the order books, it should take a massive order of almost 2000BTC to reach this price now. According to the charts, that did not happen (the volume in those spikes was about 100BTC). Therefore it was not a massive bought order but some kind of bug/error in their API. Dont you think so?
That does seem to be a likely explanation. Looking at the 5m chart, there seem to be two separate spikes above 2000Eur but both with rather low volume (100BTC)
Of course it was a "small" order that produced that spike BECAUSE IT BYPASSED THE ORDER BOOK.
But the problem is not in the API:
XBT/EUR
Last
€1,894.680
High
€2,082.958
Low
€1,757.400
24 Hour Volume

Weighted Avg

There was real coins being bought at that price... but not from me or others even if we had lower sell limit orders in place way before that spike happenned. (days).
So the question is... who was the fortunate guy that sold them at that high price BYPASSING THE ORDER BOOK?
I was watching Kraken at that time. I was waiting in a queue for two hours and had very little to do except keep refreshing all my coin charts, including the Kraken app. I did not see that price reached or any unusual fluctuations in the price. I do not believe it was real, or if it was it must have been so momentary that no other prices were hit in between. A fat-fingered buyer perhaps? Someone who thought they were trading USD instead of EUR??
It could be a fat finger or most probably a short squeeze. That doesn't matter... the price reached 2082€ (as you can see on kraken site itself as high price today), I had sell limit orders placed on the ORDER BOOK from several days ago at 19XX€ which should have been honored. The price cannot reach higher without honoring orders in the order book. It's as simple as that.
Even if the site became unusable during that spike, orders already in the order book BEFORE the fat-finger/short squeeze must be honored (My orders were there from several days ago). YOu can even halt the trading for some issue, but the price cannot get higher without honoring previous lower orders. That's how an order book (should) works.
I also had a sell limit order today that did not execute but should have, at 12:51 GMT+2. I saw the chart, new my order should've executed, went to Kraken to go place a buy order, but no joy.
I have opened the issue not only on a support ticket but also in the Kraken thread:

Please contribute as I am sure there are many people affected by this issue.
