If you've used our formula, you may have wished it updated faster — like you're used to with . This hasn't been possible yet due to Google Shees' technical limitations for third party developers. However, with this month's release, we've now implemented a quotes and daily candles update process via bulk downloading.

The new formula don't just support faster downloads — . That means you can bundle all your real-time quotes in a single request using a single formula. You'll be able to build a large table of stocks and request prices on everything all at once. The Add-on will make a single API call to Market Data and fetch all your prices at the same time — no more refreshing delays!

You could download all 500 prices of the S&P 500 in a single request — all without worrying about exhausting the quotas that Google places on your account. It is this process of combining all your quotes in a single formula that will allow a lightning fast update of your sheet.

We haven't forgotten about our API users, either. Bulk stock quote and stock candle downloads are available for API users as well. There are two new endpoints for this, stocks/bulkquotes and stocks/bulkcandles. These endpoints use most of the same parameters as the single quote / candle endpoints, so the integration into your application will be very quick if you are already using our existing endpoints.

Expanding our functionality to cater to your needs, we've added support for relative dates and times! Now, you no longer need to be restricted to specifying exact dates. Whether it's , , or even , our system understands and processes it for you. This allows you to easily "hardcode" dates into your Google Sheets formulas or API calls and get data that is forever updating relative to the current day/time. Perfect for screeners or dashboards.

More new tickers this month! We added support for that quote on NYSE and NASDAQ. For NASDAQ-listed stocks we support the 5 letter ticker and for NYSE-listed preferred you can use the original NYSE symbol or the more common root symbol and dash. We've prepared an article that explains how these symbols work.

The optionchain formula in sheets now allows you to use the keyword "LIMIT" to limit the number of strikes displayed to the strikes that are close to the money for any given expiration. For example, the formula would return the 4 strikes closest to the money for next month's AAPL option chain. You can combine LIMIT with other filters such as ITM or OTM to return 4 in the money or 4 out of the money strikes.

If you don't know the option symbol for the contract you want to look-up, you no longer need to worry. Just write out the option using natural language and the OPTIONLOOKUP formula will now understand you. Try it out yourself:

As long as the input includes (1) stock ticker (2) expiration date (3) strike price (4) call/put then the formula will work. It doesn't matter what order you use or how you format the dates. You can even put all this data in 4 different cells and use 4 cell references:

We haven't left API users out of this update. at /options/lookup/ that allows you to make use of the same functionality. It will return a properly-formatted option symbol that you can then use with the quote endpoint. Read the docs for full details.

Most common natural-language option formats have been added, . This should allow you to directly generate option quotes after downloading your position at your broker. However, if you find that you are making requests in natural language that the system does not understand, please do not hesitate to report that to us in the helpdesk. We'll get any missing formats added as they are brought to our attention.

If you're a Sheets user and you have 5 minutes to spare, you can learn to use OPTIONLOOKUP with this quick video tutorial. It has never been easier to work with your broker's CSV files.

We now have coverage of most indices including a customer request made on our feature request board for VIX3M, VIX6M, VIX9D, VIX1Y. We have also added new OTC stock tickers, including lightly traded tickers that were previously excluded. Market Data now has 100% coverage of U.S. equity markets, indices, mutual funds, equity and index options.

In the coming months we will be focusing on , with the goal of total U.S. financial market coverage. If you've already made the decision to purchase a Market Data subscription, this additional data will be added to your subscription at no additional cost to you. Our commitment is to never raise prices on existing customers.

As part of our urgent feature requests program, we added two new features this month: . Check the API & Sheets Documentation for full details.

The optionchain endpoint now includes a real-time quote for all options in the chain and the filtering of the chain is now based on real-time data rather than the previous day's data. It is no longer necessary to use the quote=true parameter to get a real-time quote.

If you're a Sheets user and you didn't check out last month's tutorial, now's the time! Learn to use our new OPTIONCHAIN formula with our video tutorial. Filter by expiration, strike, DTE, delta, and learn how to build an options screener.

You can now request (or even the current minute when requesting intraday candles). Before this update, candlestick data was only updated once per day in the middle of the night. Now we are pleased to offer you a real-time feed of this data. No new formulas or endpoints are needed. Just use the STOCKDATA or INDEXDATA formulas in Sheets or the STOCK CANDLES or INDEX CANDLES endpoints in the API. We also added the special relative date keyword "now" that will always refer to the current time. This will let you create formulas or API calls that always give you the latest candle data.

As part of our urgent feature requests program, we added three new features this month: for quotes. These were not big user requests (you won't find them with many upvotes on our feature request board), but individual Market Data users needed these features urgently and now it they are available to all users. , we're happy to implement features by request. Check out the details of this program if there's something you urgently need added and you're willing to pay for its development. The only condition is that we don't develop private features. Any feature we develop will be made available to all Market Data users after it is finished.

You can now use the STOCKDATA formula in Sheets or the STOCK CANDLES or STOCK QUOTE endpoints in the API with mutual fund tickers. These tickers are always 5 characters and end with an X, for example: VFINX (Vanguard S&P 500 Index Fund). Remember, mutual fund NAVs are updated once a day and use a single daily price, so they won't have bid/ask values; they aren't traded the way ETFs are; and the candles will give duplicate values for each OHLC price for the day.

We've added a MARKETSTATUS formula in sheets and a new MARKET STATUS API endpoint. and get the open/closed status of the market on that day.

You'll see two new attributes in all our stock and index quotes: and . This will display the change in dollars and in percent from the previous close. These values are now automatically included in the API responses and in Sheets when you request "ALL" columns for a stock or index quote. You can also request them specifically using change or changepct in the attributes part of our formulas or the columns parameter of the API.

You can now use the new formula to download hundreds of options at once in Google Sheets. With you were limited to a single option in each formula. With you can download every option for a single expiration at once.

There are more than 25 columns you can use in the output. Use "ALL" to see them all and then pick just the ones you need. Column output is also ordered in the same order as you input them!

You can get the expiration date you need by using North American date formats "MM/DD/YYYY", a cell reference with a date in sheets, or timestamp format "YYYY-MM-DD". What's perhaps the best feature of the formula? You can now use "DTE 30" and get the expiration 30 days from today. Each time you open your spreadsheet this will update giving you an expiration 30 days in the future.

That means you can use "100-200", "100,200", or "<100" in the strike filter to get the exact strikes you want. What's even better? "DELTA 50" and get the at the money option.

And of course you can to calls, puts, in the money or out of the money options and eliminate the rest. Check out the video tutorial to see the formula in action or read our blog post for a complete tutorial with examples.
