Bruce,

Do we have Vertical/Horizantal filter indicator in TC? I can't find it

Also what other indicators are out there that measure the strength of the price trend?

Thanks

For 28 periods use the following in a custom PCF indicator:

(MAXC28-MINC28) / SUM(ABS(C-C1),28)

You might want to try the Kaufman Efficiency Ratio.

We don't have a VHF indicator, but the first formula I found for it would seem to be something like the following where the period is 20.

`(MAXC20 - MINC20) / SUM(ABS(C - C1), 20)`

But this doesn't completely make sense to me in that the net changes cover an extra bar. So I would think the correct way to write this should be the following instead.

`(MAXC20 - MINC20) / SUM(ABS(C - C1), 19)`

Or mayby adjust the numbers the other way.

`(MAXC21 - MINC21) / SUM(ABS(C - C1, 20)`

The denominator in both indicators are the same

It is the Abs Sum of the difference between each day over the look back period

But the numerator on VHF is Highest High or Highest Close - Lowest Low or Lowest Close during the look back period while in Efficiency Ratio the Numerator is the difference between todays Close and the close of your look back period

Am I correct here?

Yes, you seem to be correct in your understanding of the difference between the two.
