1 value

• KAMA value

Range of KAMA values is the same as the range of the source values.

1 signal

• if filter_period is less or equal than 0, then returns signal when KAMA crosses source value. When source crosses KAMA upwards, returns full buy signal. When source crosses KAMA downwards, returns full sell signal. Otherwise returns no signal.

• if filter_period is greater than 1, it uses same cross between source and KAMA, but with additional filtering using standard deviation.
