A method of displaying a symbol representative of changes in price during a time period includes receiving a plurality of prices, each price occurring at a different corresponding time, determining, from the received plurality of the prices, an open price occurring at an initial time and a last price occurring at a last time, the time period extending from the initial time to the last time, determining, from the received plurality of prices, a highest price occurring at a first time within the time period and a lowest price occurring at a second time within the time period, generating, by a charting engine, a symbol, based on the open price, the last price, the highest price, and the lowest price, and displaying at a particular position, by the charting engine, the symbol, which includes a first indicator indicating the first time corresponding to the highest price and a second indicator indicating the second time corresponding to the lowest price.
