Installation for GNU/Linux Systems

1. Install Redis (some steps might require root privilege)

http://redis.googlecode.com/files/redis-2.0.4.tar.gz
tar xzf redis-2.0.4.tar.gz
cd redis-2.0.4
make
cat redis.conf  | sed -e 's/^timeout.*/timeout 0/'  | sed -e 's/^daemonize.*/daemonize yes/'  > /etc/redis.conf
cp redis-server redis-cli /usr/local/bin/
redis-server /etc/redis.conf
Note that the redis-server must be manually started with this approach. It's also possible to configure a system script to automatically start redis-server: see your system administration manuals.

Note also that you may wish to edit other parameters in the /etc/redis.conf configuraiton file.

2. Install IQ Feed

This step probably requires q Windows system and possibly the iqcast repeater service for Windows. Make sure that you can access the IQ Feed from the machine that bars will run on with, for example: 
telnet localhost 5009

3. Install bars

wget http://illposed.net/bars_1.2.tar.gz
tar zxvf bars_1.0.tar.gz
cd bars
make
make install
./bars
Note that, once running, your process table should show *two* copies of the bars program--the parent process talks to the iqfeed server, and the child process talks with Redis.

The bars manpage shows how to access bar data from R. The raw ticks are also available from Redis, just look up the symbol name to retrieve them in text format.
