Data Feed

A data feed is the live stream of prices, quotes, and market depth a broker or platform sends into a trader's charting and execution software. In prop trading, this usually arrives as free Level 1 data covering top-of-book bid and ask prices, with optional paid upgrades like Level 2 depth or extra exchange coverage.

Why it matters

A delayed or interrupted feed means a trader reacts to stale prices, which can distort entries, exits, and challenge results without the trader realizing it. Many futures-focused firms require signing a market data agreement, often called a Non-Professional Data Agreement, before real-time data activates; skipping or mishandling that step causes avoidable setup delays.

Live data

Example

A futures trader opens a funded challenge and signs a Non-Professional Data Agreement for CME Group data. For a short window after signing, generally under two hours per documented guidance, prices may show as delayed. Once the account status updates, the trader gains real-time CME Level 1 data (CBOT, CME, COMEX, NYMEX) on their platform. Separately, a trader on an index or event-based platform may see a feed from aggregated institutional-grade data providers rather than a direct exchange connection, since not every prop platform connects straight to an exchange.

Common misconception

Traders often see a data subscription line item inside their broker platform (Tradovate is a common example) and assume it's a personal charge, then cancel it, not realizing the prop firm covers that cost. Cancelling cuts off their own live data and triggers the delayed-price problem they were trying to avoid. Traders also assume every glitch is a technical outage, but documented troubleshooting shows most issues trace back to setup timing, subscription changes, or account activation, not a broken feed.
