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.

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

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.

Thanks

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

Thank you for all your help.

Bruce, would you please help me to write four PCFs for 7 period RSI:
1)  Yesterday's 7 period RSI > 30.
2)  Today&#39;s 7 period RSI < 30
3)  Yesterday&#39;s 7 period RSI < 70
4)  Today&#39;s 7 period RSI > 70.

The setting for 7 period RSI:
RSI Period:  7
Use Wilders Smoothing
Avg Period: 1
Average Type:  Simple

Thanks
