Market data refers to all the information and statistics that show how financial instruments (like stocks, bonds, commodities, or currencies) are performing in the market.
It’s the real-time or historical information investors and traders use to make decisions.
Key types of market data include:
- Price Data – Current price, opening price, closing price, highest and lowest price.
- Trading Volume – How many shares/contracts were bought and sold.
- Bid & Ask Prices – The highest price a buyer is willing to pay (bid) and the lowest price a seller will accept (ask).
- Market Indices – Data from collections of stocks, like the S\&P 500 or Dow Jones, to show overall market trends.
- Historical Data – Past prices and volumes used for analysis and predictions.
- News & Events – Company announcements, earnings reports, or global events that can affect prices.
📊 Example:
If you check Apple’s stock, you might see:
- Price: \$190.25
- Change: +1.2% today
- Volume: 52 million shares traded
- Bid: \$190.20 | Ask: \$190.30
That’s market data in action.
