user63808: Why do candles sometimes have different positions and sizes even when the open-close-high-low are all of the same value?
For instance in one coin I saw: DigitalNote(XDN) the price has been consistent at 0.00000030 for a while, yet the candles are of different sizes.  

In this image, the last two candles both have O=0.00000030 C=0.0000030 H=0.0000030 L=0.0000030
Yet somehow the candles are of different sizes. 
What's going on?

user77455: Something isn't right. If all OHLC values are the same, then there should only be a single dash, which looks like a hyphen as opposed to the bars that you show in your picture. A bar indicates that there was a price fluctuation in the recorded time period. 
What I have found in my exploring of various API providers is that there are many that don't understand how to implement candle charts, or how to calculate candle data. I think the problem is that so many people in the community know about cryptocurrencies, but don't have a clue as it applies to financial charting and trade signals in general. For these reasons, I use ClueDex for my OHLCV data provider as they seem to have figured it out.
