With the chart snippet you posted, bar7 is incr black and included in the long tape. If that bar was incr red, the RTL long would have been drawn to not include this bar. The fact that it was an increasing volume bar was informative and gave an indication of which tape to include the bar within. Price and volume inform each other. If it was a decreasing volume bar it would also be informative in that by the memory of the pattern, where does decr red volume occur? Where does decr black volume occur?
