This is set for the 5-mn TF (you can change N for other TFs):

Timeframe(Daily)
VolAvg = average[30,0](volume)
//
Timeframe(default)
N = 6                     //1=30mn-TF, 2=15mn-TF, 3=10mn-TF, 6=5mn-TF, 30=1mn-TF
FirstHalfHour = 093000
IF OpenTime = FirstHalfHour THEN
   c1 = (summation[N](volume)) > (VolAvg / 2)
ENDIF
c2 = close > 4
Cond = c1 AND c2
SCREENER[Cond](VolAvg AS "Vol average")

At line 6 you must write when the first HALF HOUR ends.

There are some issues:

• to work on a 30-minute boundary,  you must use a 30-minute (or lower) TF
• it’s (almost) impossible that a 30-minute VOLUME be > the average volume of the last 30 days!

Anyway, the previous code had a few bugs, this the updated code:

Timeframe(Daily)
VolAvg = average[30,0](volume)
c1     = VolAvg > 250000
//
Timeframe(default)
N = 1                     //1=30mn-TF, 2=15mn-TF, 3=10mn-TF, 6=5mn-TF, 30=1mn-TF
FirstHalfHour = 153000
c2 = 0
IF OpenTime = FirstHalfHour THEN
   c2 = summation[N](volume) > (VolAvg / 2)
ENDIF
c3 = close > 4
Cond = c1 AND c2 AND c3
SCREENER[Cond](VolAvg AS "Vol average")

Selecting ALL the security lists, I was returned just 2 signals.

What do you mean, what average is it?

Hi Roberto,

It is the 30 day average DAILY volume not the 30day average volume.

I know what I wrote. What I can’t understand is what your quoted sentence means!

You are talking about the SAME average, how can they be different from each other?
