Need quick clarity about Close[0] and Open[0].

 
I understand these are arrays and the [0] represents newest info. My concern is that the current candle that hasn't closed , has definitely opened. So it has a value for Open[0] but if I call Close[0] , since this latest candle hasn't closed yet , is this Close array pulling from previous close? or does it use current price as Close[0]. I hope my question is clear. Thanks for the Help. First post.

Close[0] is equal to Bid
