EMA Today=(Value Today∗( 1+DaysSmoothing))+EMA Yesterday∗(1−( 1+DaysSmoothing))

what is ( EMA Yesterday)

can i use
ema= sum(EMA Today,14)

this for SMA from AB

sum(C,14) / 14

The formula "sum( CLOSE, 14 )" returns the sum of the preceding 14 closing prices. A 14-period simple moving average could be written "sum(C,14) / 14."

when i try to do the formula for any N period i will face one point called (initial value )

like so

With the Efficiency Ratio (ER) and Smoothing Constant (SC), we are now ready to calculate Kaufman's Adaptive Moving Average (KAMA). Since we need an initial value to start the calculation, the first KAMA is just a simple moving average. The following calculations are based on the formula below.

Current KAMA = Prior KAMA + SC x (Price - Prior KAMA)

if it is the first calculation how to do the second.

or after the first step of (initial value ) what the is the second.
