Hi,
I have two formulas: TSV Tilt Today:.

((TSV27 + TSV27.15) / 2 - AVG(TSV27,16)) * 12 / 182

and TSV Tilt Yesterday:

((TSV27.1 + TSV27.16) /2 - AVG(TSV27.1,16)) * 12 / 182

I'm trying to customize these in order to use them to create a scan that will find stocks that have an upward sloping TSV linear regression line.   Can you help?

What is the Period of the Linear Regression Line?

The period is something fairly short term--maybe 18 days or so.

Thanks,

Anna

You could just calculate the Slope of the Linear Regression Line directly:

Slope of LR18 of Simple TSV27:

(8.5 * TSV27 + 7.5 * TSV27.1 + 6.5 * TSV27.2 + 5.5 * TSV27.3 + 4.5 * TSV27.4 + 3.5 * TSV27.5 + 2.5 * TSV27.6 + 1.5 * TSV27.7 + 0.5 * TSV27.8 - 0.5 * TSV27.9 - 1.5 * TSV27.10 - 2.5 * TSV27.11 - 3.5 * TSV27.12 - 4.5 * TSV27.13 - 5.5 * TSV27.14 - 6.5 * TSV27.15 - 7.5 * TSV27.16 - 8.5 * TSV27.17) / 484.5

Just add a > 0 or < 0 to the end. You may wish to review the following:

Hi Bruce, could you please help me to write a PCF for a downsloping LR21 of Simple TSV21 makes its first upward change of angle and the slope of LR21 of Simple TSV21 is still sloping down?  Thanks

TSV21 > TSV21.1 AND TSV21.1 < TSV21.2 AND 10 * (TSV21 - TSV21.20) + 9 * (TSV21.1 - TSV21.19) + 8 * (TSV21.2 - TSV21.18) + 7 * (TSV21.3 - TSV21.17) + 6 * (TSV21.4 - TSV21.16) + 5 * (TSV21.5 - TSV21.15) + 4 * (TSV21.6 - TSV21.14) + 3 * (TSV21.7 - TSV21.13) + 2 * (TSV21.8 - TSV21.12) + TSV21.9 < TSV21.11

Hi Bruce, I back test the PCF, which you wrote on 5/29 on stock symbol "TTD". Several signals shown on 3/27/2018, 4/2/2018, 4/5/2018, 4/9/2018 and 4/11/2018 are not what i want to have.  How do i modify the PCF so that the signal occured on 4/12/2018, which is the first TILTUP signal of downsloping LR21 of Simple TSV21.

So you aren't interested in simpe TSV21 making its first upward change of angle while the 21-period linear regression slope of simple TSV21 is down?

You are just interested in the 21-period moving linear regression changing from going down to going up?

The following would work in TC2000 v18.

`TrueInRow(3 * FAVG(TSV21, 21) - 2 * AVG(TSV21, 21) > 3 * FAVG(TSV21.1, 21) - 2 * AVG(TSV21.1, 21), 2) = 1`

As would the following slightly shorter but more opaque fomula.

`TrueInRow(41 * TSV21 + 19 * TSV21.21 > 60 * AVG(TSV21.1, 20), 2) = 1`

But you would need to check the values of both the current and previous bars in TC2000 v7.

`41 * TSV21 + 19 * TSV21.21 > 60 * AVG(TSV21.1, 20) AND 41 * TSV21.1 + 19 * TSV21.22 <= 60 * AVG(TSV21.2, 20)`

Thanks, Bruce.  Yes, I am interesting the LR21 changing from going down to going up.

The three formulas in my Friday, June 01, 2018 3:40:12 PM ET post are all for the MLR21 of simple TSV21 going from down to going up.

Thanks, Bruce, all your formulas are working fine.  I do not know how you can get those coefficients (41, 19, 60), but it works.  Thank you for all your help.
