Volatility measures how much a stock price (or any other asset price) is likely to move over a period of time.
Think of it in terms of emotion. You have a volatile friend. At the beginning of the night, they can be smiling and laughing and generally having a good time. An hour later, they're ugly-crying in a bathroom stall. Very volatile.
Some stock prices are like that as well: $20 today...$8 tomorrow...rally to $35 next week. Very volatile. The volatility ratio represents a technical indicator meant to compare near-term price movements with its longer-term volatility.
To calculate the measure, first look at a stock's price range for the day. Subtract its low price from its high price. That equation gives you today's range, known as the TTR (today's true range). Then figure out the ratio of the TTR with the longer-term volatility. This second part gets measured by the average true range for whatever period you're looking at (50 days, 200 days, etc.). The ratio then looks at today's range versus the average range over a period of time. How much more (or less) volatile is the stock today compared to its recent average? That question represents the heart of the volatility ratio.
The measure is meant to clue investors into possible changes in a stock's behavior, predicting breakouts or other changes in its chart pattern.

Finance: What is the U.S. Mint?4 Views
Finance allah shmoop what is the u S mint It's
this tasty sweet smelling plant that can be grown in
the united states So it's you know us mint But
it's not the u S Mint that would be this
place and these three places actually yeah there are currently
for mints in use one each in philly san francisco
denver in a west point So what exactly do they
do there Take mint plants and convert them into delicious
melt in your mouth treats so we can cleanse our
palace after a hefty meal at our favorite garlic filled
italian restaurant Well no not quite The u S Mint
is responsible for one hundred percent of our coinage That's
pennies nickels dimes quarters of this one Whoever that busty
woman is if it can be found in a change
purse It started out here or here or here or
here Well the u S Mint was created by congress
in seventeen ninety two when our forefathers realized that there
was no way to make any of the jukebox is
work So yeah we needed small change because well back
in their day pretty much the only thing that cost
over ninety nine cents was a thirty foot yacht or
a trip around the world on a mule so we
needed something other than paper currency that started at a
dollar And while the u S Mint was born well
the mints use precious ish medals but not so precious
that they're not willing to melt them and crush them
and form them into likenesses of dead presidents Well the
medals are fed through a series of fancy machines until
coins pop out on the other end Well typically the
quarters and dimes and so on that we use on
a semi regular basis but sometimes also commemorative coins Yeah
that's included in there too Well like when the country
turns two hundred years old when we want to recognize
an important person or event from history or when you
know workers that the men are bored of coining aeneas
Now this is all what they do Additionally there's a
facility at fort knox where all of the u S
Bullion is stored and no gold and silver bullion not
bullion Birbal yang's you difference in french but don't get
any crazy ideas about robbing the place That would be
like while trying to break into fort knox common misconception
the mint doesn't print paper currency that would be under
the purview of the bureau of engraving and printing which
will also put your loved one's name on a champagne
flute for just twenty nine ninety five So yeah the
u S mint does coins The bureau does dolla dolla
bills right Those annual crosstown softball cames really gotten pretty 00:02:31.958 --> [endTime] fierce
