To be honest, I don't understand the problem, what makes solving it
difficult. There are at least 4 ways to determine whether you are in the 24
Hr mode (afl or no afl):
1. As mentioned before: File/Database Settings/Intraday settings/Filtering
2. Look at the chart which will show big time gaps in the day session
3. The chart will show large daily gaps in the day session between close and
next day's open. (In 24 Hr session there is only aMonday 0:00AM gap)
4. If all that fails, ask Janeczko for the 2 or 3 line flag code
Having said that, here some code which perhaps solves the problem (whatever
it is).
Good Luck
Title = EncodeColor(4)+ _DEFAULT_NAME()+"; "+EncodeColor(1) +
StrFormat("{{NAME}} - {{INTERVAL}}; {{DATE}}; O=%g, H=%g, L=%g, C=%g,

SetChartOptions(0,chartShowArrows|chartShowDates);
SetBarsRequired(inDaily/Interval(),0);// Necessary to determine Day Session
or 24 Hr Session
DayChange = Day()!= Ref(Day(), -1);
StDay1 = ValueWhen(DayChange, BarIndex(), 1);
StDay2 = ValueWhen(DayChange, BarIndex(), 2);
NumDayTimeBars = StDay1 - StDay2;
_24HrBars = inDaily/Interval();
Cond=WriteIf(NumDayTimeBars/_24HrBars<0.95,"Day Session","24 Hr Trading");
//Cond<=1, because certain brokers don't display all 24 Hr data and also in
case of occasional data loss:
//for example IB does not display 12:00-12:15 AM in Forex (4-4:15 PM CST)

display of bar indices is desired

Subject: [amibroker] Re: Day Session or 24 Hour from AFL...?
Your zoom stuff is great... what's great about it is that you can construct
any two datetimes and zoom to those values... they don't even have to be
part of your AFL arrays... i.e. your arrays can be small but you zoom back
to wherever you want...
The problem is constructing datetimes can be a quite clunky... especially if
you want to zoom back a given number of bars... when you start looking at 24
hour vs day filtering it starts to get messy... and no-one likes messy
code!!!
