stock.py

retrieve (almost) realtime stock quotes

This is a quick and dirty script that retrieves stock quotes from finance.yahoo.com. The quotes are delayed by about 15 minutes by Yahoo. The script displays the change from the previous close, the previous close, the opening price, the days low and high, the price/earnings ratio, and the days volume. Display is colour-coded: green for gains, red for losses. It also has a 'ticker' ('-t') switch to monitor the price. By default it updates every minute, but you can change this by passing the number of seconds via the '-i' or '--interval' option..

Here is sample usage and output:

[you@yours]$ stock.py -q rhat goog amd novl msft aapl

The script can also do currency conversions, again using info from Yahoo Finance. I am not sure if these currency symbols are international standards or specific to yahoo but you can see them all at the finance.yahoo.com website. Here is an example of usage:

[you@yours]$ stock.py -c 100 CAD USD
100.00 CAD at 0.908600 is 90.86 USD as of 1:19pm 5/10/2006
[you@yours]$ stock.py -c 100 cad eur
100.00 CAD at 0.710200 is 71.02 EUR as of 1:20pm 5/10/2006
