A method of displaying a symbol representative of changes in price during a time period, the method including receiving a first intra-time open price, a first intra-time high price, a first intra-time low price, and a first intra-time close price corresponding to a first intra-time period in the time period, receiving a second intra-time open price, a second intra-time high price, a second intra-time low price, and a second intra-time close price corresponding to a second intra-time period in the time period wherein the second intra-time period occurred after the first intra-time period, determining whether the second intra-time high price is higher than the first intra-time high price and whether the second intra-time low price is higher than the first intra-time low price, in response to the determining that the second intra-time high price is higher than the first intra-time high price and that the second intra-time low price is higher than the first intra-time low price, incrementing a higher-high-higher-low-price counter value, determining whether the second intra-time high price is lower than the first intra-time high price and whether the second intra-time low price is lower than the first intra-time low price, in response to the determining that the second intra-time high price is lower than the first intra-time high price and that the second intra-time low price is lower than the first intra-time low price, incrementing a lower-high-lower-low-price counter value, and generating and displaying, by a charting engine, the symbol, which illustrates a relationship between the higher-high-higher-low-price counter value and the lower-high-lower-low-price counter value.
