$456 on Bitstamp could be the low for the day or week. It was $453 on BTC-E and $462 on Bitfinex so far.
UPDATE: While the USD market had already been stabilizing, China wasn't happy and started dumping bitcoins which caused the USD market to follow and break the very fragile bottom we had established when I published this chart. I was thinking about making another chart about the incoming extended crash based on the CNY trend before it happened with USD a few hours ago, but dismissed it because it's obvious based on the tight stop loss shown here.
