SierraChart feed/bridge reborn - Realtime Bitcoin charting
ANN: New version of Sierrachartfeed and direct-download history files, working again (and fixed again Feb 10 2014)
Original post with details of what this software is, read first:
Sierrachartfeed gets data from bitcoincharts.com for multiple exchanges. Each time they change some API "feature", it seems to break other people's software. This is thefourth fifth "rebirth" of working software I've written since slush gave up maintenance of sierrachartfeed.

For history older than five days, before first running sierrachartfeed
The normal Bitcoincharts API only has five days of data available. If you have never run sierrachartfeed for a particular exchange ticker before, it will only get the last five days. However, if you want all trade data from the beginning of time, you can download some big files first:
You will also need to re-download a new CSV if it has been over five days since you last ran sierrachartfeed.
The SCID filenames are different from previous versions, to avoid using or overwriting obsolete data. New filenames are of the format mtgoxUSD-p4.scid (where p4 indicates precision 4).

Original post with details of what this software is, read first:
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 Bitcoin markets->Sierrachart bridge, which enable real time Bitcoin charting in Sierrachart.

For history older than five days, before first running sierrachartfeed
The normal Bitcoincharts API only has five days of data available. If you have never run sierrachartfeed for a particular exchange ticker before, it will only get the last five days. However, if you want all trade data from the beginning of time, you can download some big files first:
- Go to this web page: http://api.bitcoincharts.com/v1/csv/
- Download the individual CSV files for exchange tickers you wish to track
- Extract the gzipped files to the SierraChart data directory (C:\SierraChart\Data)
(a utility like 7-zip can help you with this) - When you first run sierrachartfeed and specify a ticker with CSV, data will be imported from this file first
- The CSV file will be renamed after all data from it is imported
You will also need to re-download a new CSV if it has been over five days since you last ran sierrachartfeed.
The SCID filenames are different from previous versions, to avoid using or overwriting obsolete data. New filenames are of the format mtgoxUSD-p4.scid (where p4 indicates precision 4).
