Today is a tip day on investing ...
The TICK is an indicator that measures the NYA Index (New York Stock Exchange)
and provides an internal statistic of the stock market.
The TICK summarizes the number of stocks that are increasing in price versus
the number of stocks that are decreasing in price from the previous
price quote.
Some interpret it as buying and selling, but that is not entirely accurate.
An up-ticking stock is one where the most recent change in price was positive;
a down-ticking stock is one where the most recent change was negative.
The Tick is calculated by subtracting the number of down-ticking stocks from
the number of up-ticking stocks. For example, a tick reading of +500 means
there are 500 more up-ticking stocks than down-ticking stocks. The TICK is
recalculated continuously throughout the day. Normal tick levels are between
+500 and -500; tick readings of plus or minus 1000 are generally considered
extreme and often represent short term overbought and oversold conditions.
(It is often used by day traders who look for extreme tick readings to determine
these short term overbought and oversold conditions.)
Application of TICK data in the market ...
Below is a 20 minute chart over an 8 day period for the TICK and the SPY (S&P
500 ETF). I plotted Exponential Moving Averages of 6, 10, 15, 30, 60, and 89.
With these moving averages, you can see when the TICK is in an up trend by
moving sharply above or below the 60 and 89 EMAs.
Look at the movement and trending of the TICK and then focus your eyes below
to the corresponding SPY movement. When the TICK is above zero, it is positive
and when below zero, it is negative.
This is a useful tool for day traders, and it is also a useful tool for
longer term traders who simply want to get the best "buy in" price levels. There
are other indicators and settings I use along with this to know what to do
when the TICK is trending sideways. If you don't use the TICK, maybe this
is something you might want to explore and learn more about.
The reason the TICK is so useful, is that it measures what is happening on
the NYA Index where the majority of the Institutional trades are made, along
with "program" trades.
