I do not know the name but it only interprets that the direction of the arrow shows up or down with the indicator of the direction of the arrow to the top as an increase and arrow direction down as a decrease in prices in each candle, to be said to be the opening or closing candle in my opinion not because there are still needles and rods that are shown perfectly, it only explains one candle ride or down to the candle.

Btw what platform do you use? I was the first time I saw the graphic bar like you showed the display style like that, is that an exchange or just an ordinary platform?
