SierraChart is desktop application providing a professional Trading, Real-time and Historical Charting, and Technical Analysis platform for the financial markets. It's not so intuitive as other platforms, but once you learn how it works (and remember few shortcuts), it is very strong tool for professional technical analysis. Because of lacking real trading tools for Bitcoin economy, I decided to write simple Mtgox->Sierrachart bridge, which enable real time Mtgox charting in Sierrachart.
How to start- 1. Download and install SierraChart software (use default settings and data directory)
- 2. Download SierraChart feed for MtGox market.
- 3. Start feed in a console (no parameters required, list of all parameters: sierrachartfeed.exe --help)
- 4. Start SierraChart software
- 5. Go to File->New/Open Intraday Chart and select mtgoxUSD.scid
- 6. Customize your view using F5 (chart settings) and F6 (analysis/studies) menus
- 7. Enjoy real time mtgox charting!
After those steps, you should see something similar like following image:

Used settings/indicators in this screenshot: 60min candles, Volume, Current price line, Moving Average-Exponential, vertical line every week. There are hundreds of other indicators and studies. I'm sure you will find something which fit your needs...
Linux supportOlder Sierrachart releases works also in Linux under Wine. Main charting functionality in older versions is the same, they improved mainly DOM and trading functionality, which is disabled anyway on mtgox. Last version I tested on Linux was 559 (details:

sierrachartfeed.exe is using mtgox's websocket API for real time updates and bitcoincharts.com for downloading historical mtgox prices. Thanks tcatm for providing this API. Bitcoincharts.com currently provide 3 day history for everybody, longer history will be probably available for some small fee.
Source for sierrachartfeed.exe is available
here.
this is good but does it do realtime during off hours (NYSE closing) or in middle of night?
