Changing options in one part of a custom project changes options in other parts. In this example, changing the commission value in the WF Matrix step, also changes the commission value in the Retest Markets step. Then, by merely observing the value in a 3rd step (WF 10,000) causes the values to change in the previous two steps.
Until now I thought such behavior was limited to the quantum world.
Status changed from New to Fixed
