title: Why do I get this error: not enough values to unpack (expected 5, got 4)?
body: <p>Basically I want a graph with 3 subplots. The 2nd plot will be a candlestick chart and is the one I am currently working on now. However, I keep getting a "not enough values to unpack" error and I don't really know why???</p>

  <p>The chart I get also does not seem right. It's fully red, but for candlesticks that closed higher than it opened, I have set the color to be green but no green candles appear. I have arranged the columns in the 'OHLC' order to correspond with the function, so I don't know why it comes out like this too.</p>
