HiLo Chart

High-Low (HiLo) chart is most often used to illustrate price movements over time. Vertical lines here represent price ranges (the highest and the lowest) during some period (e.g. a month, a day, an hour, etc).

HiLo is a truncated version of OHLC Chart without ticks indicating Open and Close values or it may be considered a Range Bar Chart with a very thin column.

High-Low is good when visualizing stock market data, so one can compare price ranges over the periods of time and make some decisions based on this information.
