Continuous Price Curve

Representing the price of a security as a curve is the simplest and most natural type of chart.
Over a chosen time period, price points are connected by straight line segments:

• close price (most common case)
• or open price
• or highest price
• or lowest price
• or median (equal to the average of the high and low)
• or typical (equal to the average of the high, low, and close)
