This question is, which exchanges? The answer is only US-listed companies it seems. US-listed companies' data is already widely available so this isn't useful to me. Would be interested if other exchanges might be on the roadmap.
The exchanges would be mainly CBOE, NYSE, NASDAQ, OTC. Yes, mostly it is US-listed companies. Thank you for your proposal, we will add this to our to-do list.
TSE?
We don't have it at the moment, we will add it in the near future.
