Have been watching these charts a fair bit and have noticed that some of the highs and lows are not being reached as portrayed by the charts,
this could be defective software or the exchange could be doing it on purpose to fool traders.
I noticed on some coins, but seemingly not all, the high it marks on the chart corresponds with the value you put in on the order, not what price it actually matches at. So for example on DOGE, if you put in a buy at some ridiculously high price (say .1 BTC) but only a volume of a few thousand, the chart will mark it as having hit a high of .1BTC even though your few thousand coins will all match and buy at market (like .00000054). So the chart makes it look as though it spiked and went back down even though it never even moved past the lowest sell point. It would not shock me to see other coins doing the same. They seem more interested in adding every coin under the sun than making sure what they already have works. And that has been true for many months now.
As for the overlap in the order book, it is lag. That has been happening for months and months too. Sometimes it seems like they get it cleared up and then it happens again. I like cryptsy but to be honest I don't think Vern has the database skills to make it work on his own. There is clear database optimization stuff that is sorely needed over there.
