Quote from Trader KGB:
The only thing that bothers me about QT's candles is you cannot use both solid and hollow candles at once in the same chart.
That means if you have a down day that closes higher than the open, you'll see a green candle, even though overall it was a down day. Vice versa if you're up on a day but close below the open, you'll have a red candle on an up day. That paints an imcomplete picture.
Take a look at the attached chart comparison, you'll see exactly what I mean. QT is on the right, with just its simple red/green. On the right is stockcharts.com, which uses both hollow and solid candles, allowing you to see a better picture of what happened on each day.
I've emailed Gerry Medved about this, but he said it cannot be coded differently. The only thing I might be able to do is code paintbars to show a different color on those types of candles, perhaps a different shade of red/green..

Don't even get me started on why certain candles are different sizes in those identical charts of the $HSI, that's troubling... Also, if I load up any identical chart in QT and stockcharts.com, almost every indicator spits out a different value from each source.. *sigh*
