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
