The word "intraday" literally means "within the day". With this in mind, Intraday Stock Data involves reporting all of the price changes that a certain stock might have in a given day. So rather than showing changes over the course of several days, Intraday Data shows fluctuations that occur in a single day.
Because of this, Intraday Stock Data is good for traders who want to do something called backtesting their trading system. It is also important for short-term traders who want to make several stock trades during any given trading period. This group of traders must pay really close attention to any intraday price changes which then might cause them to benefit financially from super quick changes in the price.
As a made-up example of intraday stock changes, for example, let's say that this Monday, during trading during the day, McDonald's common stock rose to an intraday high of $18 before closing at $18.32
Sometimes, the term "intraday" is used to describe securities that trade during regular business market hour. These include things like stocks and ETFs, but not mutual funds, as these must be bought from a dealer.
Visually, the Intraday Stock Charts are usually portrayed as bar graphs and are reduced into time increments like one minute, five minutes, 10 minutes, 30 minutes, one hour, and 24 hours. In most cases, each Intraday Stock Chart is pretty limited in how far back it can display data on stock prices. Most show results for just the past 2-10 or so days. But if you would like more information on your stocks rather than just one day's worth, historical intraday charts can often be easy to get at various financial reporting websites or sometimes even as part of a package offered by your paid broker.
The term intraday is also often used to describe the latest lows and highs of a security. As an example, saying something had a "new intraday high" means the security rose to a new high |
