Hi,
this loop example can be a starting point ( limited
to 500 previous bars)
SetBarsRequired(<FONT color=#ff00ff
size=1>100000,<FONT color=#ff00ff
size=1>100000);
period=255<FONT face="Courier New"
size=1>;
for ( i=period; i<BarCount ; i++)
{
k=0<FONT
face="Courier New" size=1>;
for ( j=1<FONT
face="Courier New" size=1>; j<period ; j++)
{
if(H[i]>H[i-j])
k++ ;
}
Tot[i]=k;
}
Plot(tot,<FONT
face="Courier New" color=#ff00ff size=1>""<FONT face="Courier New"
size=1>,2<FONT
face="Courier New" size=1>,<FONT face="Courier New" color=#ff00ff
size=1>1);

Subject: [amibroker] Re: days since
higher price
I should check - am I reinventing the wheel here? My basic
aim is to be able to find new highs without limiting the search to a
certain period (e.g. if I search for prices crossing the prior 100 period
high, this will miss the break of a 110 day high, and so on). Is this
built into a function? or has someone already written the code for
this? I've looked but can't find anything.
