Free real-time stock chart data usually comes from just one data provider, which means you might not see all the price movements occurring in the stock or exchange-traded fund (ETF) you're day trading. That could be a great deal, depending on your goals. A number of websites and platforms provide real-time stock charting capabilities for one-minute, five-minute, and other intraday charting time frames.
