What is the best indicator to evaluate a stock's volatility? I want to trade only volatile stocks. Thank you.

beta works.  good luck

ATR.

Average True Range

Thanks diceman

Dave landy has a pcf to rank stocks more volatile then other stocks

I specifically continue to use TCv7 because of its dynamic logarithmic grid scale percentages.  This pcf only returns equities with a logarithmic percentage of 7% or more when using zoom 3.  It's great for filtering out all those stodgy issues that might take a week to move 3% or whatever.  You can easily customize the percentage between grid lines by  changing the 7 which represents 7% to your choice.   Go back to archived webinars by Boxer or Logan; they both love this feature in v7 and explain its importance.  One of the Worden staff offered a version of this pcf that works with v12, but I can't find it, maybe they'll publish it again.

100 * ((100 * MAXH222 / ((MAXH222 / MINL222) ^ (1 / 12))) \ 1) / ((100 * MAXH222 / ((MAXH222 / MINL222) ^ (1 / 6))) \ 1) - 100 >= 7

Thanks for sharing Fpetry. Harry Boxer and Tina Logan are two of my favorite teachers. I still use V7 for some things but have migrated my scans over to V12. It makes a great filter so maybe we could ask Bruce to chime in with a version for V12

The formulas were introduced in the Chart Scale Increment topic. That said, there are absolutely no advantages to these calculations over just choosing an arbitrary period of time and using that to determine what percentage the high is above the low for that period unless you specifically want to match the number in the lower right hand corner of a logarithmic chart in TC2000 version 7.

For example, for the 222-bars given in the formula provide by fpetry, the simpler formula would be:

100 * (MAXH222 / MINL222 - 1)

While for 100 bars the simpler formula would be:

100 * (MAXH100 / MINL100 - 1)

If you wanted to kind of normalize this result over the period of 1-year, the first formula would become:

100 * (MAXH222 / MINL222 ) ^ (252 / 222) - 100

And the second formula would become:

100 * (MAXH100 / MINL100) ^ (252 / 100) - 100

It would allow you to make direct comparisons of values using a different number of bars in their calculations. That said, I'm not really sure if that is particularly useful.

That was quick. Thanks Bruce. As always your skill and your opinions are highly valued.

Well, I think beta is the best, where you can find the best indicator to evaluate the stock...
