Ambiguity | Candle stick from ticker data

ankithjoseph

I am trying to form a 1 min candle from the ticker data received.


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


The confusion is regarding the OPEN and CLOSE values of the particular candle.
the charts shows the value as follows.


The ticker for first second had two values
2023-07-11 15:26:00 19508
2023-07-11 15:26:00 19509

How is the open price considered for candle plotting?
Kindly explain.

It can be any tick received for that timestamp. This article explains in detail.
