The Problem
Every year, trading ops teams waste hundreds of hours on a process that should be automated.
Trading ops teams manually check exchange websites, parse PDFs, and copy holiday dates into spreadsheets every year.
Each ETRM system needs calendars in a different format — Endur XML, Allegro CSV, RightAngle SQL. Manual conversion is error-prone.
A missed holiday means failed settlements, broken forward curves, and compliance risk. Mid-year changes make it worse.
How It Works
Automated scrapers check 20+ exchange websites daily for holiday schedule changes and mid-year revisions.
Every change is reviewed before publication. No silent updates. You get notified of exactly what changed.
Pull calendars via REST API, download files, or receive webhook notifications. Endur XML and Allegro CSV included.
