Mainland disclosures: prepare comparable source documents
Locate mainland company reports, preserve cumulative periods and revisions, and avoid treating a public page as a redistribution license.
Read process & limits →CoTrading · Data & sources
Start with your files. Know where data comes from.
Free sources, your own files and your own accounts. Check permissions, definitions and coverage before starting research.
Return to original disclosures
Public access does not mean unrestricted redistribution. Follow source access rules and preserve retrieval time and references.
Use what you already have
Keep readable reports, original theses or CSVs in your own environment. This site does not receive your files.
Connect within your permissions
Configure provider accounts in your tools, not this site. Check quota, costs and reuse rights before connecting.
Source guides, not a hosted data API
No paid data procurement, data resale or key-application endpoint in this release. Future services depend on actual licensing and costs.
