The video above (on the right) shows real time analysis and an explanation between different platforms for the NYSE Tick.
The $TICK symbol is listed on the New York Stock Exchange (NYSE) and keeps track of all the stocks on the NYSE on a tick by tick basis, tracking how many stocks are in an uptick, how many are in a down tick, and how many are in a side tick. The $TICK symbol is the difference in the number of stocks in an uptick and those in a downtick. There are approximately 3700 stocks on the NYSE. For example, if there are 2500 stocks in an uptick and 1200 in a downtick, then the $TICK symbol will be +1300. This number can be a + or – number. Another example, is if 2500 stocks are in a downtick and 1200 stocks are in an uptick, the $TICK symbol will be -1300.
The $TICK symbol usually has readings between +1200 and -1200. This symbol only represents the NYSE stocks and not the entire universe of all stocks but can be a good indicator of the short term direction of the stock market and can be useful when trading stock index futures.
How the NYSE TICK is different on different trading platforms and from different data providers?
In June 2012, we have found that the TICK symbol is different in different trading platforms. We have focused on just one platform and data provider for many years but as we look at different platforms we have learned more about how the NYSE Tick is calculated. Each quote provider calculates the NYSE Tick. It does not come from the New York Stock Exchange. Different quote providers use a slightly different list of NYSE stocks to make the calculation and the update interval can be slightly different as well.
Trading systems results between different platforms can vary because of this and for our Tick Count Trend trading system, we use different bull and bear threshold values. In our NinjaTrader platform using Kinetick data, the symbol is ^TICK and the bull and bear threshold are +/-100 while in Tradestation the symbol is $TICK and the thresholds are +/- 200. These are the thresholds that match the best between platforms going back one year from June 2012.
