Your challenge
The right API can make or break your portfolio management tools

Good portfolio tools need perfect data on dividends, stock splits, and security details. With the wrong API, positions show incorrect values and performance numbers break. Our API gives you all this critical data through one simple endpoint, so your allocation tools and risk calculations actually work. No more emergency fixes when client reports show wrong numbers. Just reliable data that keeps portfolio tools running smoothly.

Ensure Accurate Portfolio Valuations
  • Incorporate critical trading status indicators and auction prices into daily pricing logic.
  • Reflect all halt, pause, and resume events in asset valuations.
  • Avoid pricing errors tied to missed market context.
Track Corporate Actions and Position Adjustments
  • Detect and account for stock splits, auction movements, and IPO phases.
  • Timestamped events help apply adjustments to historical positions with precision.
  • Full message feed ensures no action goes unnoticed.
Maintain Consistent Historical Context
  • Use nanosecond-precision timestamps to align events with historical trades.
  • Replay exact market states to support forensic performance analysis or post-mortem reporting.
  • Great for both ongoing position management and historical auditing.
Power Allocation, Risk, and Reporting Tools
  • Deliver correct inputs for IRR, allocation weight, and performance attribution models.
  • Prevent data inconsistencies that lead to client-reporting issues.
  • Automate downstream data checks with complete, structured inputs.
Simplify Data Integration
  • Single, RESTful API delivers metadata, trades, quotes, and event signals in one place.
  • Standardized format means less time on ETL and more time building user value.
  • Avoid the need for multiple providers or proprietary SDKs.
