Hi,
I'm new to this language and I'm trying to understand what actually this code is doing:

Code: 
[... code here ...]

input rollingPeriodMinutes = 60;
 
def factor = (SecondsFromTime(Market_Open_Time) / (60 * rollingPeriodMinutes) / 100);
def rolloverTime = if factor == Round(factor) then 1 else 0;

rec H1 = compoundValue(1, if !rolloverTime then if high > H1[1] then high else H1[1] else high, high);
rec H = compoundValue(1, if rolloverTime then H1[1] else H[1], high);

[... code here ...]

Can any of you understand what actually at the end "H" is?
Please, any help is really appraciated🙏
Thanks a lot,

Julian

this study draws 7 hourly pivots, on the current day.

compoundValue() is like an if then, they choose to do the middle parameter or the 3rd parameter.
the first parameter is a barnumber.
if the current barnumber <= the first parameter, then process the 3rd parameter.
if the current barnumber > the first parameter, then process the 2nd parameter.

rec H = compoundValue(1, if rolloverTime then H1[1] else H[1], high);

if the current barnumber <= 1 , then h = high
if the current barnumber > 1 , then h = if rolloverTime then H1[1] else H[1]

an equivelent formula
def h = if barnumber() <= 1 then high
else if rolloverTime then H1[1]
else H[1];

rolloverTime is true at the day open , 9:30 , and every 60 minutes after (bottom of the hour).
at the bottom of the hour h = h1[1] , the previous value of h1.
for the next 59 minutes, h = h[1] , the previous value of h.

Oh ok! So may u confirm me the following example:

If now is 14:27, inside H C L i have the high close and low of the hour bar starting from 12:30 and finishing in 13:30 . When the time will be 14:31, in the variable there will be the H C L of the bar from 13:30 -> 14:30 ... is this correct?

i don't know. i'm not go to analyze all the lines of code to figure out what the values will be.
I would add a chart bubble to the end of a study to display the values. then zoom in to the time in question and see what is happening. sometimes i add an if then in the color parameter,
(if ... then color.yellow else color.gray)

Code: 
addchartbubble(1, low*0.997,
h1 + " H1\n" +
h + " H\n" +
l1 + " L1\n" +
l + " L\n" +
c + " C\n" +
o + " O\n" +
x_var + " x\n"
,color.yellow, no);
