I am building an API for a smaller Stock Market. What are some crucial functions, features and calculations should it have out of the box?

So this is for a stock exchange in a different country than the US. But I want it to be good if not great. This is also an ongoing experiment by the way.

So far, the API can return:

• price
• price change
• previous close
• open
• average daily volume
• stock exchange name
• market cap
• book value
• ebitda
• dividend share
• dividend yield
• earnings share
• day's high
• day's low
• year high
• year low
• 50 day moving average
• 200 day moving average
• price earnings ratio
• price earnings growth ratio
• price sales
• price book
• short ratio
• trade datetime
• historical (start date, end date)
• stock information
• refresh

What other stuff should I add? Nothing too niche, but i definitely want to add more stuff. Suggestions most welcome!
