Hello, thanks for writing in. The strategy builder needs indicators to have a plot so it can read the indicator data, it is not able to read if there is a drawing object on the chart. The indicator you are using will need to have a boolen plot added in that will be false on bars where there is no arrow and true on bars where there is an arrow. An unlocked script can read a chart for drawing objects using the DrawObjects collection:
