# What is Data feed?

> Also called: Market data feed, Rithmic, dxFeed, CQG, Tradovate data

**In short.** The data feed is the service that delivers the market's trades and order book to a trading platform: Rithmic, dxFeed, CQG and Tradovate's own are the usual ones for futures prop firms. The feed decides what the footprint and the heatmap can show (full depth or ten levels, every trade or aggregated) and whether a platform such as [DeepCharts](https://my.deepcharts.com/redirect/deepchart?affId=OFF&utm_source=fillprint&utm_medium=affiliate) can connect to a given firm.

**On today's board.** 4 of the 14 firms on the board list [DeepCharts](https://my.deepcharts.com/redirect/deepchart?affId=OFF&utm_source=fillprint&utm_medium=affiliate) among their platforms (code OFF through the partner link). Data checked October 15, 2026.

A prop firm licenses one or more feeds; a platform supports some of them. A firm 'accepts [DeepCharts](https://my.deepcharts.com/redirect/deepchart?affId=OFF&utm_source=fillprint&utm_medium=affiliate)' when the two meet: the board lists, for each firm that routes DeepCharts, the feed behind it. Market data is billed per exchange on top of the platform licence.

For order flow the quality that matters is unaggregated trades and the depth of book; feeds differ on both. The article on prop firms that accept [DeepCharts](https://my.deepcharts.com/redirect/deepchart?affId=OFF&utm_source=fillprint&utm_medium=affiliate) lists the three questions to ask a firm about its feed before paying.

Futures trading involves substantial risk of loss and is not suitable for every investor. fillprint is an independent publication, not a broker or a prop firm.

Some links are affiliate links: if you sign up through them, the firm or DeepCharts pays us a commission, at no extra cost to you, and often with a discount for you. Affiliate links are marked and carry rel="sponsored". Being an affiliate never moves a firm up the board. Firms without a program stay listed, marked “no affiliation”.
