This agreement explains how you may use the market data you obtain with a ZaFeed market Key (real-time quotes, historical K-lines, snapshots and streaming, together the "Data"). It forms part of the Terms of Service.
1. Permitted use
- Use within your own systems or your team's systems: research, backtesting, quantitative strategies, risk control, internal reporting and monitoring.
- Processing the Data and displaying it to your users in your own website or app (for example charts, quote cards or watchlists), as long as you do not offer downloads of the raw Data or an API for it.
2. Prohibited use
- Reselling, sublicensing or redistributing the Data, including providing the raw Data to third parties through APIs, files, data feeds or similar means.
- Using the Data to build a market data service that is the same as or similar to ZaFeed.
- Publishing, selling or lending market Keys, or letting anyone outside your team use them.
- Obtaining data beyond the markets you have purchased, or trying to bypass authentication or rate limits.
3. Exchange and data source rules
The Data comes from exchanges and other data sources. Some exchanges have their own rules on how data may be displayed or used. If we need your cooperation (for example crediting the data source or limiting where the data is displayed), we will let you know by email or in News, and you must follow that notice.
4. Data accuracy
The Data may be delayed, interrupted or incorrect. It is for reference only and does not constitute investment advice. Do not rely on ZaFeed data as the sole basis for trading.
