Patent ID: 11488216

Abstract:
A method of displaying an HLL (high, low, last) type symbol representative of changes in price during a time period in which a highest price occurred at a first time within the time period, and a lowest price occurred at a second time within the time period, the method includes receiving a last price corresponding to a third time within the time period, comparing the last price to the highest price and the lowest price, in response to the comparing step, updating the highest price with the last price and updating the highest price to correspond to the third time if the last price is greater than or equal to the highest price and updating the lowest price with the last price and updating the lowest price to correspond to the third time if the last price is less than or equal to the lowest price, generating, by a charting engine, the HLL type symbol by drawing a spatiotemporal relationship between the highest price, the lowest price, and the last price in accordance with a selected symbol rendering method, wherein a height of the HLL type symbol indicates a difference between the highest price and the lowest price and a width of the HLL type symbol indicates a difference between the third time and an earlier of when the highest price occurred and the lowest price occurred, and displaying, by the charting engine, the generated HLL type symbol at a particular position.
