That is probably the main problem : Even if I make it on timer, that does not guarantee that the bars are going to be formed at precise time (timer can be delayed and can "drift" from the desired time). So, I don't think that, from the users side, it is possible to make seconds based offl...

Right, it would be strongly time-dependent.  But, if you can set it to start at nn:nn:00,
it would already be something...   It could be a very convenient tool, available
on other trading platforms by default.

Thank you!  (Just for a while) I'm interested in small TFs charts,
which could be useful for analysing rapid movements
of some commodities and instruments.   Though, maybe
it's not a good idea to watch such small TFs...

Hi, Everybody!

Dear Mladen,
have you ever coded an indicator / expert
preparing charts with TFs smaller than 1M (e.g. 10s)?
Of course, they would probably be built online using ticks, or so...
Such charts / TFs could be sometimes quite useful,
and are available on some trading platforms.
