Real-time traders use intra-day data (prices that are constantly updating throughout the day) to make decisions about when to buy and sell during the trading day, this also allows you to look at different time frames (examples, 1 Min, 8 Min, 30 Min etc.). End-of-day traders access their data (Date, Open, High, Low, Close, Volume, and Open Interest) for the day after the markets have closed. We have products designed specifically for each type of trader.
