In addition to data sources, Polaris relies on the following providers to operate the service. None of these providers receive your financial data for resale purposes.
Market data is refreshed at variable intervals depending on the source: intraday prices (~15-minute delay outside premium feeds), end-of-day closings, weekly or monthly macro series. Polaris is not a real-time trading platform.
Despite our verifications, errors or omissions may occur in the data we relay. The data is provided "as is", without warranty of accuracy or completeness. Always cross-check with the original source before any investment decision.
Polaris does not generate its own financial data. Our added value is in aggregation, cross-referencing, editorial synthesis and contextual reading — not in creating new data.
