yes!
in an OHLC chart, candles represent Open, High, Low, Close and also the volume.
in a small exchange like cryptopia that people usually don't go to trade certain pairs like those small forgotten ones, there is no trades in long periods. for example there can be 0 trades in 12 hours or even days. (although they remove such pairs) and that means no candle to show.
there is also another thing called "spread' that causes another kind of gap which is more like a jump. this means there is a big gap in between 2 order books. the buy for instance is ending at 100 satoshi while the sells start at 500 satoshi!
in this case if 1 trade happens now of type "BUY" there will be a candle at 100 satoshi and if 6 hours later another of type "SELL" happens there will be another candle at 500 satoshi, hence creating a big gap in between which looks like a jump in hourly chart.
Thanks.
