Bar chart values are inaccurate
On the borders of Thick Bars on the chart, you can find prices that do not correspond to OHLC values of the current price bar. The reason for such behavior is the distortion of the bar height because of its width. In the screenshot, you can see a blue arrow showing AAPL, a D bar, plotted as Thin Bar, and red arrows are showing borders of AAPL with D bar plotted as Thick Bar.
