A number of websites and platforms provide real-time charting capabilities for 1-minute, 5-minute, and other intra day charting time frames, and some of them do so for free. That could be a great deal, depending on your goals.
You might want to keep a few considerations in mind, however, before you jump in.

Free real-time data usually comes from just one data provider, which means that you might not see all the price movements occurring in the stock or exchange-traded fund (ETF) that you're day trading. You'll have to pay if you want to receive all official price data from a market.
That said, free real-time day trading charts are an excellent backup data source on the off chance you lose quotes from your broker. They're a great training tool for new traders who are looking to study day trading and create strategies based on how prices move in real time.
Where Does the Data Come From?
Free stock market data is provided by BATS, an electronic exchange that processes trades on U.S. stocks then publishes those transactions in real time. Websites and charting platforms use that data to provide real-time charts to their users.
These free real-time charts only show the stock transactions that occur through the BATS exchange. The charts don't show the transactions that occur through all the other electronic exchanges that compose the U.S. markets. BATS data represents an approximation of what's happening in real time. You'll see some of the price movements and transactions, but not all. Volume data is approximated as well because the stock charts only track volume that's processed by BATS.
When you pay for official real-time stock market data and charts, you receive the price and volume information for all the electronic exchanges that compose the U.S. stock markets, such as the New York Stock Exchange and NASDAQ.
The BATS exchange is frequently used in actively traded stocks so a transaction will likely go through on BATS at each price level the stock moves to. The charts turn out to be quite accurate in this respect. In lower volume stocks where fewer transactions occur, a transaction might not go through on BATS at each price level where a transaction on another electronic exchange takes place. In this case, you're missing pieces of information on your free charts that paid real-time charts would show.
