So you have to list everything?
Either enumerate them all
or shift OBJ_ALL_PERIODS by a required number of bits (timeframes), it seems that in your case it must be shifted by 9 bits

Igor, could you please describe the theory how to calculate how many bits to shift.
Igor, could you please describe the theory of how to calculate how many bits to shift.
all TFs that can be generated by the terminal are written in the helphttps://www.mql5.com/ru/docs/constants/objectconstants/visible
constant OBJ_ALL_PERIODS is 1 1111 1111 1111 1111 1111 1111 i.e. all 1's
if we shift bitwise to the right, then the left side will be filled with zeros
count the number of TFs listed above OBJ_ALL_PERIODS , I counted 9 pieces, maybe one wrong - it is easy to check
SZZ: you can do a combination of shift + OR, and get to display all the TF and the one we deem necessary to add, something like that:
it should be able to display everything below PERIOD_H1 and the TF PERIOD_H4

Thank you, but it's not a theory, it's more specific about the current case. So how did you calculate 9? Or have you calculated only for mql4... because in mql5 the periods are much longer.
Thank you, but this is not a theory. This is a more concrete case. But how did you calculate 9? Or you have calculated only for mql4 ... Because there are much more periods in mql5.
I counted from the mql5 help and gave a link to mql5!
It's not theory, it's practice! And you like to argue - that's a fact! )))
ZZY: Your example with subtraction would work correctly, but you have to "start somewhere", I would start from OBJ_ALL_PERIODS again, deduct all unnecessary periods from it
HH2 | OBJ_PERIOD_H3 | OBJ_PERIOD_H4 | OBJ_PERIOD_H6 | OBJ_PERIOD_H8 | OBJ_PERIOD_H12 | OBJ_PERIOD_D1 | OBJ_PERIOD_W1 | OBJ_PERIOD_MN1
can be calculated and used via #define

When arguing, you don't put a question mark, while in my text you only put questions.
And now I understood where 9 comes from. Turns out it's a shift from the maximum... I was counting from the beginning.
Everything else is up to the individual.Now I understand where the 9 is coming from. Turns out to be a shift from the maximum... I was counting from the beginning.
There is no way to do it from the beginning - bitwise shifts always fill the vacated bits with zeros, in principle this problem can be solved with logical NOT - invert the bits, but I have no terminal - I don't remember how to do bitwise NOT in MQL, and I don't want to read online help

Igor, this is not serious. If you can't argue, it's just a flop. If you don't want to prove your point, you'd better not join the discussion at all...

Hmm, what are we talking about? I have to prove that
that I should set flags to 1 in all TFs described in help higher thanOBJ_ALL_PERIODS by counting 9 lines?
Get the basics of binary counting, it's obvious, I can't prove 2 x 2 = ?
;)

That's not what I mean.
"And use logical NOT to solve - invert the bits, but I don't have a terminal - I don't remember how to do bitwise NOT in MQL, and I don't want to read the online help".
I mean either give me a proof or don't muddy the waters ))))
