The GapRunner RTX Extension is designed to identify gaps between bars and between sessions and extend those gaps until price returns to fill them. Gaps can be detected from the previous close or from the previous price extreme. An option is available to detect gaps in day session data on intraday charts. The nearest up and down gap prices may be stored into consecutive C# or V# variables and then plotted on other charts easily thru reference lines attached to those V#/C# variables.
