## Next Steps?
1. First of all, we need to know which mandatory fields you cannot provide. Please, send us feedback about the fields.
2. And then we're going to investigate how we get that unavailable data.
3. We might want to arrange meetings with you or another partner (specially for offline stock data) to find answers for these fields.
