Kaufman’s Adaptive Moving Average (KAMA) was created by Perry J. Kaufman and presented in 1998 in his book “Trading Systems and Methods, 3rd Edition”. The main advantage of KAMA over other moving averages is that it takes into consideration not only the direction, but also the market volatility. KAMA adjusts its length according to the prevailing market conditions.(source: Wikipedia)
// parameters :
// Period = 10
// FastPeriod = 2
// SlowPeriod = 30
Fastest = 2 / (FastPeriod + 1)
Slowest = 2 / (SlowPeriod + 1)
if barindex < Period+1 then
Kama=close
else
Num = abs(close-close[Period])
Den = summation[Period](abs(close-close[1]))
ER = Num / Den
Alpha = SQUARE(ER *(Fastest - Slowest )+ Slowest)
KAMA = (Alpha * Close) + ((1 -Alpha)* Kama[1])
endif
return kama
