SMA = average[10] = (close)

SMA = average[10,0](close)

Ema = average[10,1](close)

https://www.prorealcode.com/documentation/average/

defparam drawonlastbaronly = true



if barindex > 30 then


// average!
EMA1 = average[20,1](close)


//ExponentialAverage!
EMA2 = ExponentialAverage[20](close)



// calculated ema
n = 20                                   // lookback
k = 2 / (n + 1 )                         // constant
ema = close[0] * k + ema[1] * ( 1 - k )  // 'close'
              

drawtext( "EMA1:  #EMA1#",0,0)anchor(middle,xshift,yshift)coloured("yellow")
drawtext( "EMA2:  #EMA2#",0,-20)anchor(middle,xshift,yshift)coloured("red")
drawtext( "ema  :  #EMA#",0,-40)anchor(middle,xshift,yshift)coloured ("Green")
endif


return /*
*/       EMA1 coloured("yellow")style(line,5) /*
*/     , EMA2 coloured("red") style(dottedline,3)  /*
*/     , ema coloured ("Green") style(line,3)
