dooglus, it is probably safe to say, that Bitstamp BTC/EUR price is a much better representation of BTC value in EUR. it's a regular exchange, with higher transaction volume than bitcoin.de, just it may have not reached the daily transaction volume of Kraken yet, but with Kraken's service, that will eventually happen.
I think people care more about the actual highest trade of the day rather than the weighted average, even though a single tiny high-priced trade doesn't really mean anything much.
We didn't make new all-time high prices today - but did make a new all-time high daily weighted average.
