The old R2D2 had too much flip flop thrashing of red/blue line & markers, due to tendency to gravitate to center of action;
This version has relocation, & change of behavior, of key point line. The beneficial trajectory & momentum of R2D2 has been preserved and improved. Also the location of the line, now stays a calculated distance away from center of action, utilizing knowledge of recent highs and lows.
Parameters are change to reflect new input requirements and redesign of calculations.
