EMA value at specific time (label)

[Robby Luca]

Hi, I’m trying to get a label that shows an EMA value at a specific time.

For example, I want a label with the 50ema value(price) at 9:30am.

I haven’t been able to figure out how to do this.
Thank you.

Well, I tried one bit of code and it was close but didn't work... This one works:

declare upper;
def expavg = ExpAverage ( data = CLOSE, length = 50);
def expAtHalfNine = if 
    ( secondsFromTime(0930) crosses above 0 ) or
    (secondsTillTime(1600) > 0 and secondsFromTime(0930) > 0)
    then expAtHalfNine[1] 
    else expavg;
AddLabel(yes, "50 EMA @ 9:30:" + expAtHalfNine, color.blue);
plot line = expAtHalfNine;

You can remove the plot line if you want... I just put it in as a sanity check.

Happy Trading,

Thank you @mashume
So I tried it and during regular market hours it works perfectly, but during premarket/afterhours it shows the actual 50ema price rather than at 9:30.

Change this bit around:

def expAtHalfNine = if
    ( secondsFromTime(0930) crosses above 0 )
    then expAtHalfNine[1]
    else expavg;

see how I removed this bit:

 or
    (secondsTillTime(1600) > 0 and secondsFromTime(0930) > 0)

that was the thing changing it after and before market hours
