## Notes

`https://api3.sgx.com/JsonRead/chartdata` still returns `Not a valid request !` for all guessed parameters (`qryId`, `code`, `noCache`).

- The current `www.sgx.com` frontend does not appear to call this endpoint.
- **Use the modern chart endpoints instead:**
  - `SECURITIES_API_URL`: `/charts/historic/stocks/code/{code}/{period}` and `/charts/intraday/stocks/code/{code}/1d`.
  - `INDICES_API_URL`: `/charts/historic/pid/{pid}/{period}` and `/charts/intraday/pid/{pid}/{period}`.
- Include `Origin`/`Referer` headers for `api3.sgx.com` calls.
