high & low of 1st 4hr bar using 30min TF

[shakib3585]

Hello,

I'm striving to pinpoint the high and low levels of the first four-hour trading bar, encompassing the pre-market period, utilizing 30-minute aggregated data. I have attached a code, but it is not able to hold the data constant throughout the trading period by using 30 minute data. My aim is to establish constant high and low values based on the first four-hour bar, which can then be monitored through 30-minute interval aggregation. Please correct.

Thanks

def firstBarNumber = if GetDay() <> GetDay()[1] then BarNumber() else firstBarNumber[1];

def high1 = if BarNumber() == firstBarNumber then high(period=aggregationPeriod.THIRTY_MIN) else high1[1];

def low1 = if BarNumber() == firstBarNumber then low(period=aggregationPeriod.THIRTY_MIN) else low1[1];

def high2 = if BarNumber() == firstBarNumber+7 then high(period=aggregationPeriod.THIRTY_MIN) else high2[1];

def low2 = if BarNumber() == firstBarNumber+7 then low(period=aggregationPeriod.THIRTY_MIN) else low2[1];

def hi = if high1>=high2 then high1 else high2;

def lo = if low1<=low2 then low1 else low2;

plot IBH = hi ;

plot IBL = lo;

your wording is confusing.
in 4 hours, there will be 8 - 30 minute time periods.
do you want to plot 2 lines,
at the high and low,
of 8 different 30 minute time periods, starting at 4am?

what chart time are you using?
what are some symbols you are looking at?

Many stocks will have very little trading in premarket. So we'll have missing bars and not much data to plot.

What I would like is to be able to plot the very first 4 hour bar high and low value using 30 minute aggregation data. The first 4 hour should encompass the premarket if there were premarket action. If not, the it will extract from RTH
