I've made this script where the horizontal
line should appear in the chart
,but it applies to all days i'd like to be
applied only on the current day.

def AP = AggregationPeriod.DAY;
def Priorclose = close(period = AP)[1];
def HighOfTheDay = high(period = AP);

plot Red = (HighOfTheDay + Priorclose) / 5 ;
plot green = (HighOfTheDay + Priorclose) *(0.7) ;

ok seems i've found out how to do it

here is the script if someone is interested:


def day = getDay();
def lastDay = getLastDay();
def AP = AggregationPeriod.DAY;
def Priorclose = close(period = AP)[1];
def HighOfTheDay = high(period = AP);
def isToday = if(day == lastDay, 1, 0);

Plot Half = if isToday then (HighOfTheDay + Priorclose) / 5 else Double.NaN ;

Plot max = if isToday then (((HighOfTheDay - Priorclose)*(0.7))+ Priorclose) else Double.NaN ;
