Re: divergence in price-indicator (How)

Hi, dimitri,

perhaps I am "blind" , but the code for trendlines is written with 
lasvalue

pS = troughBars( s1, per, 1 ) == 0;
endt= lastvalue(ValueWhen( pS, x, 1 ));
startt=lastvalue(ValueWhen( pS, x, 2 ));
dtS =endt-startt;
endS = lastvalue(ValueWhen( pS, s1, 1 ) );
startS = lastvalue( ValueWhen( pS, s1, 2 ));
aS = (endS-startS)/dtS;
bS = endS;
trendlineS = aS * ( x -endt ) + bS;
