Opportunity Addon for Warcraft gem sales.
By Nelson Minar aka Flyv. http://flyv.typepad.com/
Version 1.0. May 20, 2009.

The Opportunity addon makes it easier for jewelcrafters to recognize market opportunities for cutting and selling gems. Opportunity creates a window with a snapshot of the entire rare gem market, highlighting which gems are worth cutting and selling for a profit. It does this by looking at the current Auctioneer snapshot of the market, historical prices, and sales success history via Beancounter. I've used Opportunity for well over a year to great success.

Opportunity requires the Auctioneer Suite, including Beancounter.

This addon is being released *unsupported*. The author has no plans to improve or maintain the addon and any requests for support will be cheerfully ignored. I would be happy for someone to take the addon over and develop it themselves. The code is under MIT license so requires no permission from me, but drop me a note if you decide to take it over!

Usage:
1. Go to the auction house and complete an auction scan.
2. Open your Jewelcrafting spellbook
3. Type "/opp knock" at the console.
4. A window will pop up with a snapshot of the entire gem market.

The window contains the results from Opportunity. It has a lot of information, but once you learn to read it you can quickly pick out which gems are worth cutting.

For every raw uncut gem (such as Sky Sapphire), a line is displayed with the following information:
1. Raw gem name
2. Average gem price from Auctioneer
3. List of 5 cheapest auctions for the raw gem. Green is a bargain.

For every gem cut (such as Solid Sky Sapphire), a line is displayed with the following information:
1. Cut gem name. Coloured by status of the gem.
   Blue = profitable, White = not profitable, Red = been undercut.
2. Percentage of sales that were successful (from Beancounter)
3. Historical cut gem price (from Auctioneer)
4. Name of the seller for the cheapest gem.
5. Five cheapest auctions for the raw gem.

For a quick scan-and-cut, the simplest thing is to look at the window for gem names in blue. Then check their percentage sales success and if it's reasonable, cut a few. Much of the other market snapshot data is clutter you can probably ignore.

Ideas for future expansion: less cluttered display, automatic scanning of the live auction, clickable text so that gems can be cut right off the display window. I would be wary of expanding this addon to other professions, its simplicity is because of the one raw gem = one gem construction of Jewelcrafting.
