Indicator built upon a special moving average formula that adapt its period automatically accordingly to the market behaviour and noises. This moving average is called the OMA (One More Average), the formula come from an MT4 version found on internet.

Converted from MT4 because of a request on forum.

This version of the one more average indicator embed a step variation of the result of the calculation. The sensitivity and step size can be modified in order to adapt how the moving average respond to the step function, which is comparing how the moving average evolved between difference of actual and past data with current average true range.

The adaptive period can be more or less adaptive by changing the “speed” parameter (0.1 step). The adaptive behaviour of the formula can be shutdown with “Adaptive=0”.
