|=|, |=|, -|, |=, |=, |-|, =|, ..., ...

What are the last two symbols in this sequence?

Sorry for being so unclear. There's how I'd draw those symbols:

The pic is just for analogy, you still should end the original sequence, not this one.

Hint:

Duplication (first and second, forth and fifth) is not something you should look at in first place (not the primary logic).

Hint 2:

You meet these symbols in everyday life.

Hint 3:

Try to draw all the symbols on the paper, without spaces inside each symbol (i.e., each symbol with one solid line)

  • $\begingroup$ Does "last" actually mean "last"? That is, with those two symbols added is the sequence complete, or could it be continued on further? (Feel free not to answer; but if you intended "last" as a hint then it would be nice to know.) $\endgroup$ – Gareth McCaughan Jun 8 '16 at 16:07
  • $\begingroup$ @Gareth Nice question; the sequence could be continued, though probably not uniquely. $\endgroup$ – nicael Jun 8 '16 at 16:10
  • $\begingroup$ The hints have been updated, anyone? $\endgroup$ – nicael Jun 8 '16 at 17:06
  • $\begingroup$ so this sequence(7+2 symbols) is unique, and after 9 symbols it can be continued not uniquely? $\endgroup$ – smriti Jun 8 '16 at 18:17
  • $\begingroup$ @smriti Sort of, but after it's arguable, so I didn't require more than two symbols. $\endgroup$ – nicael Jun 8 '16 at 18:18

These are

the top halves of digits from 9 downwards on a 7-segment display

so the next two are, in the notation used here,

=|, |.

  • $\begingroup$ Yeeeey! That's great, it wasn't that clear without a pic... $\endgroup$ – nicael Jun 9 '16 at 8:38

My guess is: =| , |-

I think the sequence goes like: 2 same symbols, one unique, 2 same, one unique, 2 same, one unique.

Since the next have to be the same as the previous i just copy it. And the next i assume is this one |- because it's the opposite of the first unique element and they both completes to |=|.

  • $\begingroup$ Interesting, but it's not the rule the sequence follows (I didn't even think of that repetition). $\endgroup$ – nicael Jun 8 '16 at 14:54
  • $\begingroup$ Eh, I was sure the duplication matters :) So about to the third hint - does this mean I should draw the double horizontal lines (=) as one thicker line, and the single line as one thinner? $\endgroup$ – Nyagolova Jun 9 '16 at 6:55
  • $\begingroup$ I've clarified the question :) $\endgroup$ – nicael Jun 9 '16 at 7:17
