Post From: Article about Sierra Chart Market Statistics and their Accuracy

One thing that people do not realize, is that when you see the net TICK calculation start off at a very negative or very positive value at the very point in time where the calculation begins for the day, it must inherently be wrong. So are we saying those other calculations are wrong? Yes we are. They make no sense. We have confidence in what we say, unless the other services can explain how it is they do the calculation. Here is a chart image of the calculation from IQ Feed: http://www.sierrachart.com/image.php?Image=1466482465940.png We see the very same thing. But it does not make sense. In the past, the Sierra Chart TICK-NYSE would begin the calculation at 4 AM US Eastern time when the market begins to trade. However, because users would notice differences compared to our calculation and other services, we decided to change the start time to 9:30 AM US Eastern time. This is how it works now. Today the Sierra Chart TICK opens at 0. The basic problem is that the market data is a high-speed single stream of data. Therefore, the calculation has to start off at 0, -1 or 1 since the very first trade is going to be a single stock. It can rise up or down very rapidly from that point in a matter of microseconds but it does not make sense for it to open very negative or positive. If it does, it calls into question as to whether the calculation method is even valid to begin with. Other reasons for differences has to do with the underlying data data feed being used, but there is not an indication there is genuinely anything wrong with the underlying data feed used by Sierra Chart in the market statistics calculation. However, we will make an inquiry with the data provider about a question we have related to this. Sierra Chart Support - Engineering Level Your definitive source for support.
