What does the term 'intraday' refer to in financial data?

The term 'intraday' specifically refers to data that is collected and analyzed within the same trading day. In the context of financial markets, intraday data provides insights into price movements, volumes, and trends that occur throughout a single trading session. This type of data is crucial for day traders and others who are making rapid trading decisions based on market fluctuations.

For instance, intraday charts can show how prices change every minute or hour, allowing traders to identify patterns, entry and exit points, and overall market sentiment within that specific day. In contrast, data collected over weeks, at the end of the day, or for multiple days pertains to different timeframes and would not be labeled as intraday. Hence, the classification of financial data as 'intraday' is specifically linked to its capture and relevance within the confines of the same trading day.
