Where do you trade these? And is this graph from there?

I'm a former gox user and now a bitstamp user. To be honest- I trade on Bitstamp because I'm not interested in the drama at Gox and I'm not interested in squeezing every last satoshi of profit out of every price swing. I have a feeling a large number of Bitstamp users feel the same. We will buy and sell when the price suits our interests, but the low volume is just fine. While Gox is $6 above stamp, it feels ephemeral- I'm more convinced it's someone manipulating the market into people raising their buy orders, just to dump on them big time. It's like a cycle. I'm more then happy to sit at $6 below in exchange for a calmer market.
This. Without a closed money loop between Gox and Bitstamp, it is what it is. And while a cheaper price means you get less $ for selling BTC, it also means you can buy more coins for your cash. The relative price change is more or less the same and the gap between those two isn't always like this. There were even times, where Bitstamp was higher valued.
