Multiple region price chart display system, method, and device

An apparatus for displaying a price chart, the price chart including a plurality of regions, the apparatus comprising:

• processing circuitry configure to
• display, by a charting engine, a first region including one or more historical completed price-range-over-time-range-type symbols;
• display, by the charting engine, a second region adjacent to the first region, the second region including a current uncompleted price range-over-an-uncompleted-time-range-type symbol corresponding to an uncompleted time range;
• and
• in response to the determination that the uncompleted time range has completed, generate and display, in the first region, by the charting engine, a new historical completed price-range-over-time-range-type symbol adjacent to the one or more historical completed-price-range-over-time-range-type symbols, and erase, in the second region, the current uncompleted price-range-over-an-uncompleted-time-range-type symbol.

A non-transitory computer readable storage medium having instructions stored thereon that, upon execution by processing circuitry, cause the processing circuitry to perform a method for displaying a price chart, the price chart including a plurality of regions, the method comprising:

• displaying, by a charting engine, a first region including one or more historical completed price-range-over-time-range-type symbols;
• displaying, by the charting engine, a second region adjacent to the first region, the second region including a current uncompleted price range-over-an-uncompleted-time-range-type symbol corresponding to an uncompleted time range;
• and
• in response to determining that the uncompleted time range has completed, generating and displaying, in the first region, by the charting engine, a new historical completed price-range-over-time-range-type symbol adjacent to the one or more historical completed-price-range-over-time-range-type symbols, and erasing, in the second region, the current uncompleted price-range-over-an-uncompleted-time-range-type symbol.
