What sites do you use to track the current price of bitcoin?

[therealtimcoulter]

I made one recently (this is a real question, so I won't link to it). I'd like to see other sites that are highly popular to improve mine. Are there features that you prefer? As a trader, what is the most useful piece/pieces of information?

What have you learned from trading?

This is pretty much an open question. Would love your response.

I use this since it includes the relative value of other altcoins to bitcoin.

Do you trade multiple alt-coins?

btc-e, mtgox.

I've started using: http://bitcoincharts.com/markets/

I like how you can see each of the different exchanges and the prices on them, especially since China seems to be more and more important.

Very simple to use and you can also view the price in SEK which is nice for me as a swede.

I use mtgox just because I can take a quick peak on my phone when I want.

They have an iPhone app I use all the time and have just released an android version I believe.

I use BTC-e to check on some other coins too.

I use clarkmoody in a minimized window with sound enabled so I can hear the up/down ticks.

Then I use a few windows of bitcoinity with the exchanges I am tracking. Bitcoinity has large text which is useful since I have a PC plugged into my TV and can just glance at it to easily track the prices. It's pretty useful when arbitrage opportunities show up.  I know bitcoinity has sound also but the downticks aren't loud enough.

Just a cool little site that updates regularly.  You can choose an average of the 4 exchanges they track (BTC-e, Bitstamp, Localbitcoins, and Mt. Gox) or pick the one you use most.  It keeps the price right on the tab so you can always see the current price.  

I'm not really a trader though.  More of a hobby for me.

My go to site: http://bitcoinity.org/markets

Otherwise, I just use Python scripts to retrieve the last trading price using the various exchange API's. I pipe that into xmobar (status bar thing) every 15 minutes or so.
