hhmm from RegularTradingStart()?

[bmn]

Is there a way to convert RegularTradingStart(GetYYYYMMDD()) to "hhmm?"

RegularTradingStart(GetYYYYMMDD()) "returns the number of milliseconds elapsed since the epoch (January 1, 1970, 00:00:00 GMT) till the start of the regular trading hours on a given day for the current symbol."

Since RTH start time can vary per symbol, I would like to grab the current symbol's RTH start in "hhmm" format based on RegularTradingStart(GetYYYYMMDD())

Thank you

I have some code somewhere... I'll look for it on a usual trading day

Hey @mashume , just checking if you were able to find the snippet by any chance?

Life got busy... haven't taken a trade all week. I'll try to look this morning. I have less than 5 hours of meetings scheduled today. %-\

This may work...

declare upper;

def time = round(RegularTradingStart(getYYYYMMDD()) / 1000, 0);

input tz = -8;

def hh = floor((time / 3600) % 24) + tz;
def mm = floor((time  / 60) % 60);

addLabel(yes, "Regular Trading Hours Start: " + hh +":" + mm + " ", color.gray);

Things get ugly when you try to take into consideration converting from GMT if you have to adjust for things being > 23 or < 0. It can be done, but it gets ugly.

If this works for you, cool. If not, let me know what it is or isn't doing

PS Don't forget to adjust the timezone for wherever you want the local time. I'm on the west coast, so I'm at GMT-8 and that's the value in the input. Change to suit your location.

Thanks @mashume This is a pretty neat code.

Just have a few follow-up questions.

for \CL, it shows single digit after the colon (e.g. 6:0, instead of 6:00). Is it possible to show 2 digits (append with 0 if single digit)?
This maybe a stretch but would you be able to show how to grab start of pre-market hours dynamically using this logic (I've seen "isRollover" logic used in some studies, though I don't quite understand how that really works other than it marks the time when the day changes).
Can tz be dynamically grabbed from any sys functions (TS docs don't show anything so most probably not)?

I couldn't find a way to get tz info.

the single digit zero is not something I could figure a way around. ToS is dynamically typed so you can have strings, but I can't change variable types so that it would be a number sometimes and a string other times.

not sure about isRollOver things...

Ok sounds good. Thank you for looking into this further. Will ping back if I find a way for the latter two things.
