In the previous lessons you looked at the change of price in our security over some period of time. It might be interesting to look at the prices during the day to research when specific events occurred. The intraday data is provided in pricing bars. Price bars are a representation of the price at the open of a period, the close of that period and the high and low reached during the period. XMIM allows us to look at price bars for any period of time down to millisecond bars where intraday data exists for a series.
