Here we see the distribution of one-minute NYSE TICK readings thus far this morning. Recent posts have focused on TICK as a way of gauging intraday buying and selling sentiment.
A quick and dirty way of assessing buying and selling pressure is to consider positive and negative TICK readings as separate distributions. Count the number of one-minute readings that exceed +800 and count the number that fall below -800.
For TICK to read more than +800 or less than -800, institutions have to be executing baskets of stocks that will either uptick or downtick simultaneously. Comparing the number of +800 and -800 readings gives a rough idea of whether institutions are leaning to the buying or selling sides.
(Why plus or minus 800 as the figure? That roughly corresponds to a "significant" TICK reading: approximately two standard deviations above or below the median reading).
In environments in which we have very few +800 or -800 readings, we can infer that institutions are not active on either the buy or sell side. Those are often range markets. That is the case so far in today's trade (though buying sentiment is overall ahead of selling, with several near- 800 readings).
In environments in which we have many more +800 than -800 readings, we can infer an upside trending market. A downtrending market is one in which the -800 readings handily exceed those that are +800.
And how about environments in which we see many +800 *and* many -800 readings. Those "two sided markets" are often ones in which algorithmic/program trading is active, running markets up and down. They often are range markets, but volatile, choppy ones.
Knowing the TICK environment you're in can be very helpful in framing how you want to be trading, as it enables you to align yourself with the sentiment of large traders that move markets.
