Wilders Smoothed Moving Average

[Benoit]

Hi Guys

Looking for some EFS code please the emulate the following MetaStock code

Ref(Wilders(MP(),13),-8)

All this is is a 13 period moving average on the mid point (H+L)/2
offset by 8 periods. The trick is that it is adjusted using Wilders smoothing technique

Does anyone have this please in their arsenal of code or can they point me where it may be found?

Appreciate any and all help on this one

Cheers

Wilders smoothing can be easily implemented by using an exponential average and adjusting the period with the equation (period*2)-1.
As to your code that can be written in several ways in efs. The simplest one (shown below) is to use the offsetSeries() function to displace the ema() by the required number of bars.
The enclosed images show your code running in a Metastock chart and the equivalent efs in an Advanced Chart

function preMain(){
    setPriceStudy(true);
}

var Avg = null;

function main(){

    if(Avg==null) Avg = offsetSeries(ema((13*2)-1, hl2()), 8);
    
    return Avg.getValue(0);
}
