KForce Indicator depicts points in which prices are away from the normal movement. It does that by classifying the strength of a movement in three different ways: Light, Medium and Strong.
Yellow bars represent light movements, which indicates that prices are slightly cheaper or more expensive than usual. Usually yellow bars are not a strong signal. Orange bars represent movements of medium force. It is a good indication that prices are far way from the average, and might be considered a good entry point if one is interested in a more active system. Finally, Red bars represent prices that are intensively far away from the usual movement. These bars occur less frequently, but provide the user with more secure entry or exit points.
For smaller timeframes such as M1, M5 and M15, it is recommended to use higher Look Back Period such as 65. As for higher timeframes such as H1 and H4 it is advisable to use smaller Look Back Periods such as 25.
