Description
**Describe the bug**
Using style as charles or yahoo with candle and volume chart, some of their color don't match.
This is not happening to starsandstripes styled chart.
**To Reproduce**
Please take a look at charles or yahoo styled chart in the example page.

The second candle from the left is red in the chart but its volume bar is green.
The fifth candle from the left is red but its volume bar is green.
This is happening to my project as well.
