[amibroker] Amibroker EMA vs TS xAverage

["rop_tre" <rop_tre@xxxxxxxxx>]

Hi everyone,
Me and some friends traders are trying to see how feasible is to
transfer our systems from Tradestation to Amibroker.
We noticed that the results for the Exponential MovAvg in Amibroker
are different from the Xaverage in Tradestation.
Is there anyone that can help us translate the TS Xaverage in Amibroker?

the Xaverage code is this:

inputs: 
	Price( close ), //this is the value considered for the calc//
	Length( 20 ) ; //This are the periods to calc the Avg//

variables: 
	SmoothingFactor( 2 / ( Length + 1 ) ) ;

if CurrentBar = 1 then
	XAverage = Price
else
	XAverage = XAverage[1] + SmoothingFactor * ( Price - XAverage[1] ) ;
//the [1] means "one bar ago" - it is comparable to ref in Amibroker//


We think that since many systems for TS use the Xaverage function,
this translation would be very useful for anyone who wants to transfer
their studies to Amibroker.
Thank you
