Data and Tickers
Market-structure terms for market data feeds, tickers, screening tools, and bond quotation publications.
Market-data guidance for bids, asks, spreads, ticks, real-time quotes, stock tickers, screening tools, and session-price fields.
Quotes, prices, and market data explains how bid, ask, spread, tick, quote, trade, ticker, screening, and session-price fields should be interpreted. The section connects price-display conventions with source, timing, depth, and execution evidence instead of treating each screen label as a separate concept.
Use this branch when the issue is what price or quote data represents, where it came from, and whether it is timely enough for analysis or execution. This content is educational and does not validate any particular data vendor, trading tool, or market-data feed.
| Area | Use it when the question is about | Evidence to check |
|---|---|---|
| Market Data, Tickers, and Screening Tools | Data feeds, tickers, tapes, screeners, scanners, and market-data tools | Data vendor, ticker, exchange code, update frequency, filters, field definitions, and timestamp |
| Quotes and Executable Prices | Bid, ask, spread, tick size, quote depth, delayed data, executable quotes, and dealer indications | Quote source, delay status, bid and ask, spread, tick rule, size, condition, and tradeability |
| Session Prices and Price States | Opening prices, highs, lows, last sale, unchanged states, and session-specific price labels | Session, opening print, high-low range, last sale, close, volume, and data cutoff |
Market data is not automatically execution evidence. A screen can show a delayed quote, indicative quote, stale print, vendor-normalized field, or filtered result that differs from the order book or final execution report.
Move to Quotes and Executable Prices when the issue is bid, ask, spread, tick size, quote wording, depth, or executability. Move to Trade Reporting, Settlement, and Processing when the issue is the confirmed trade record.
