Rotation Factor (RF) – A calculation that shows the strength of the current market trend. It is calculated by assigning a value from -2 to +2 to each TPO. A value of -1 is assigned to the low of the current TPO if its low is lower than the low of the previous TPO, a value of 0 is assigned to the low of the current TPO if its low is the same as the low of the previous TPO, and a value of +1 is assigned to the low of the current TPO if its low is higher than the low of the previous TPO. The same applies to the highs. A value of -1 is assigned to the high of the current TPO if its high is lower than the high of the previous TPO, a value of 0 is assigned to the high of the current TPO if its high is the same as the high of the previous TPO, and a value of +1 is assigned to the high of the current TPO if its high is higher than the high of the previous TPO. All of the values are then added together to get the rotation factor for the current day.
