Before revision:  What is central to the function is that these cords have the unique property of attracting and repelling the price , so that the price bounces from one cord to another. The direct consequence is that prices are driven by the cords in a semi-deterministic manner (leaning towards deterministic).
After revision:  The attraction and repulsion of the price by the cords results in the price bouncing from cord to cord. Thus, the price has to be considered as driven by the cords in a semi-deterministic manner (leaning towards deterministic).
