# Quotes

## Overview

**Quotes** represent real-time price information for financial instruments, including the most recent bid and ask prices, opening and closing prices, price changes, and other market data.

In [Trading Platform], quotes are essential for most trading features, including placing and modifying [orders] or managing [positions].
Quotes ensure that users see the most current data in key UI components such as the [Order Ticket] (for accurate order entry), [Watchlist] (for tracking price movements), and [Depth of Market] (for real-time market depth).

## Provide quotes

To provide quotes, the [Datafeed API] includes three quote-related methods that must be implemented before the [Broker API]:

- [`getQuotes`] — retrieves the latest price information for specified symbols.
- [`subscribeQuotes`] — subscribes to real-time price updates for specified symbols.
- [`unsubscribeQuotes`] — stops receiving real-time price updates for specified symbols.

:::warning

Without these methods, the library cannot receive or process quotes, causing issues such as UI [loading delays] or [missing data].
