The CPR width is the distance between the TC and the BC lines of their CPR indicator. CPR indicator can be narrow, medium, or wide. A narrow CPR width is when the distance between the TC and BC is relatively small. It indicates a trending market. When the distance between TC and BC is quite huge, it is a wide CPR width and indicates a sideways market. A medium CPR width is when the distance between TC and BC is between the narrow and wide margins of CPR.
