script speed and backtest

["Stephane Carrasset" <nenapacwanfr@xxxx>]

Tz,

I have tested today a combination of gann hilo with the
Nonlinear Ehlers Filters
something like this code below, but I have had 5 differents gann hilo 
( 3 for the stock and 2 for a foreign() function).
the test was so slow!!
I am supposing that a plugin dll will be better and faster.
just tell me: I think javascript and c++ are a little similar.

pds=Optimize("pds",10,5,10,1);
mp = (High + Low)/2;
/* Distant Coefficient is calculated here using AFL scripting */ 
EnableScript("vbscript");

coef = AFL( "coef" )
pds = AFL( "pds" )
For i = pds To UBound( mp )
coef( i ) = 0
For k = 1 To pds 
coef( i ) = coef( i ) + ( mp( i ) - mp( i - k ) )^2
