There are several sites to watch the market.

BitcoinWisdom has a very nice ticker and BitcoinAverage I find very useful when I'm trading at LocalBitcoins.

CoinMarketCap and CoinIndex gives a bigger picture of bitcoin.

Andreas M. Antonopoulos has taught me a lot on the turning of the cogs in the Bitcoin machine and the difference between Bitcoin and bitcoin.

All are in my bookmarks. Look 'um up and let me know of any sites you'd recommend for my bookmarks.
