We've just published a developer section to the personalstockmonitor.com site, mirroring the content up on personalstockstreamer.

Personal Stock Monitor includes the same scripting extension API present in Personal Stock Streamer. Similar to Excel Macros, Personal Stock Monitor can be customized using VBscript (or any other Microsoft Scripting Host language). The possibilities are numerous from:

creating new indicators for charts
writing custom reports
adding calculated columns
integrating with other applications like Excel.
