The plotting of the array amazed me.
I misunderstood the formula and the array.
Your formula is of great help. My issue is hidden in another part.
Best regards
//test newday
NewDay1 = Day() != Ref(Day(), 1);
NewDay2 = DateNum() != Ref(DateNum(),-1);
_TRACE("NewDay = "+NewDay1 );
_TRACE("Day1 = "+Day() );
_TRACE("RefDay1 = "+Ref(Day(), -1) );
_TRACE("NewDay2 = "+NewDay2 );
_TRACE("Day2 = "+Day() );
_TRACE("RefDay2 = "+Ref(Day(), -1) );
Plot( Day(), "Day1", colorRed, styleDashed|styleThick);
Plot( Ref( Day(), -1 ), "RefDay1", colorYellow, styleDashed|styleThick);
Plot( Day(), "Day2", colorBlue, styleLine );
Plot( Ref( Day(), -1 ), "RefDay2", colorWhite, styleLine );
