Help with Regularized EMA (RegEMA) code

October 15th, 2011, 07:26 PM

I was hoping someone in our community here could and would convert the following Easy Language code to NT7? It's for a regularized exponential moving average out of the July '03 S&C magazine.

The only additions to the code I would like is for the average to change colors when rising or falling and to be able to select various types of averages to include EMA, SMA, HMA & WMA.

Thank you in advance to anyone who takes this on.

RegEMA: Indicator

inputs:
EMA_Length(9),
Lambda(9);

variables:
RegEMA(0),
Alpha( 2 / ( EMA_Length + 1 ) ) ;

if CurrentBar > 3 then
RegEMA = (RegEMA[1]*(1+2*Lambda) + Alpha*(C-RegEMA[1])-Lambda * RegEMA[2])/(1+lambda)

else

RegEMA = Close ;
Plot1( RegEMA, "RegEMA") ;

Hi Cory.

Thank you for your time spent on this. Something does seem off but not being a programmer, I cannot help much.

Typically, if the lambda is set to 0 then it will be exactly like the standard EMA. However, the higher the lambda, the more regularized or smoothed the average becomes.

ok , not a bad looking MA, see if it works correctly

Similar to Holt EMA?

Holt EMA

Port to EL with color.

input: price(close), gmma(40), alpha(20);
vars: mygamma(gmma), myalpha(alpha), b(0);

if alpha > 1 then myalpha = 2.0/(alpha+1.0) else myalpha = alpha;
if gmma > 1 then mygamma = 2.0/(gmma+1) else mygamma = gmma;

If CurrentBar …

calculation equation of regEMA is a little bit longer than Holt. And yes I cannibalized holt to make regEMA.

You're the MAN! Works perfectly.

Thank you once again for your time and efforts.

EMA vs RegEMA

Looks quite similar to a 'DoubleMA' EMA.
