I think that is a weekend
You might be better using barcount/cum(1)/barindex() as your basis for this.
You can always have a date determined from this. Or make certain you write
in a check that the date has the right DayOfWeek() within 1 to 5.
Cheers,
Graham

Subject: [amibroker] What is wrong with my relative strength indicator?
Below is my indicator to calculate the relative strength based on the
startpoint, say 2001/09/21
//startpint can be selected
//startpoint = Param("Startpoint", 1010921, 1000101, 1031231, 1); //default
is 2001/sept/21 = 101 09 21 startpoint = 1010921; price = Close; baseprice =
ValueWhen( DateNum() == startpoint, C); Plot( 100 * ( price/baseprice - 1),
Name(), colorBrightGreen,
styleThick );
//Ticker can be selected
ticker = ParamStr("Ticker 1", "SPY" );
price = Foreign( ticker, "C");
baseprice = ValueWhen( DateNum() == startpoint, price);
Plot( 100 * ( price/baseprice -1 ), ticker, colorRed );
It shows fine. But if I edit the startpoint and change it to 1011021,
there is no display for the indicatior. It is strange. Can anybody
help me? Thanks
Gary
