Ahh OK! Is the 23:09:10 to 23:09:09 an example or does it actually open and close at 23:09:10/09?
If yes it actually opens and closes at those times, then how come not 24:00:00? And what timezone?
If no, then what is the actual open and close time and time zone?
It's an example to help you understand. The time interval has to be 24 hours in between, so timezone doesn't matter. What matters is the 24-hour time interval between the close prices over 2 periods. If you still don't understand, I can try to draw some graphs to illustrate how it comes about.
Trying to understand. So how do I know when the next day will start or the previous day ended? Where are the two close periods?
Also, how can I get it to display the percentage from the close of the previous candle? So for example if the time frame is set to 1 hour, and the candle closed at $10 and the next one opened at $10, it would show %0. And then, as it rises and falls, it would show the percentage relatively. So at 00:58 mins if the rate is $11...it would show %10 ((11−10)1÷10×100). And if it's $9, it would show %-10.
