# May 2023 Update

Thousands of new tickers: most indices including VIX3M, VIX6M, VIX9D and VIX1Y, new OTC stocks, and further OPTIONCHAIN improvements.

-   Last updated February 5, 2024

## NEW INDICES, OTC STOCKS & OPTIONCHAIN IMPROVEMENTS

**Thousands of new tickers this month!** We now have coverage of most indices including a [customer request made on our feature request board](https://roadmap.marketdata.app/features) 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 **futures, futures options, currencies, crypto, and more**, 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.

**URGENT USER REQUESTS**
As part of our [urgent feature requests program](/docs/account/feature-requests#urgent-feature-requests), we added two new features this month: **52 week high/low data with stock/index quotes and DTE for option chains**. Check the [API & Sheets Documentation](/docs/) for full details.

## OPTIONCHAIN IMPROVEMENTS

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.
