Can someone tell me the easiest way to get back data on a given stock or index, that simply shows me the stock opening 30 minute range and the days closing high and low?
Day's OHLC you can get from Yahoo For range of first 30 mins, you'll need a provider of 1-minute historical data for Equities or Indices. Examples are: - BarChart - eSignal - Interactive Brokers - IQFeed - TD AMERITRADE - TrackData - TradeStation
