This document describes a javascript language interface that allows users to create their own custom algorithms.

Introduction

Price Spectre is a dynamic pricing agent for eBay and Half.com listings. Every user has access to several pre-defined algorithms (pricing scripts) but some users may need more flexibility or control with their pricing.

Price Spectre provides a javascript interface which allows users to write their own scripts to control their pricing. Each user-defined script is run once per pricing cycle per managed listing.

It is assumed the reader already has a beginner level understanding of javascript and programming concepts. An introduction to the javascript language can be found at https://developer.mozilla.org/en/A_re-introduction_to_JavaScript . Since pricing scripts are run server side and not in a browser all browser related javascript functions are disabled.
