Feature Requests

It would be great if we could get the option history from a specific date, or by default from the creation date of the option and return OHLCV data, and ideally the greeks. I tried searching the feature list but did not find anything that corresponds.

Being able to retrieve an array of dates of upcoming market holidays would be helpful. I currently hardcode a table of holidays in my spreadsheet, but it would be nicer to populate it automatically. I know the Market Status endpoint can be used to infer when holidays will occur by querying a huge range of future dates and picking out the weekdays when the market status is "closed", but that's awkward and inefficient.

I tried for a few hours today to guess the correct symbol for NASDAQ with no success.

I believe Websocket Data could provide a huge beneficial use and reduce API calls. The industry standards for websocket have greatly improved and it'd provide a boost

Get more historical data for indices

Many options can be traded at increment of X when price above A and increment Y when price below. An option to return a structure like this would be helpful to place a valid option trade {min-increments: {above: 0.05, below: 0.01, cutoff_price:3}}

Add fundamental data for stocks

Currently the API returns "no_data" if the from/start date of an API request exceeds the historical data age limit. It would help if the API only limited data to the plan limit and returned what you were allowed instead. This would allow for transparent plan upgrades and downgrades without code modification. (easier integration) It would also be a more accurate response, since "no_data" is not a correct response. (there actually is data).
