Please show me how to create a PCF in which:

Yesterdays closing price was >= the low of the past 63 days 

and

todays closing price is  <= the low of the past 63 days.

Thank you.

I would like to create a formula that finds all monthly securities whose high for the current monthly period  is less than the low of the previous 21 day period.

The formula I have entered below does not work. It brings up zero stocks. WHY? Can you tell me what is wrong?

MAXH21 < MINL21.21

Please show me the PCF Formula when ...

The low of the current week is > = the low of the previous week

AND 

The high of the current week is < = the high of the previous week.

Please show me the correct PCF Formula when ...

TODAYS CLOSE is greater than the OPEN of a 21 day period.
...........
(TODAYS close must be greater for the ENTIRE 21 DAY PERIOD).

Thank you for that information

Please tell me if OBV is coded using PCF code, cumulative indicator or another type of code. If another type of code please tell me what kind of code.

Thank you.

That is a very surprising answer. But, it leads me to ask you - where can I find the Custom Cumulative Indicator.?.

Is OBV calculated using the Custom Cumulative Indicator - or some other code ? My initial impression was that OBV was coded using PCF code.  

Thanks again.

I would be highly appreciative if you could give me the entire formula for OBV. I am trying to learn how to code an OBV formula so that  I can create a PCF. And, by learning how to code that,I can learn how to handle accumulations, something I have no knowledge about. And by creating the PCF I have some ideas on how to alter the formula.

Its OK with me if it does not create an exact value. What I want to know is how they deal with accumulations, since I understand OBV has to maintain the value of a high close day - hold that value and then deal with a low close day.

Thanks for your help

Would you be so kind as to give me the actual code for a PCF. I would like to include that in a pcf with other code.

Thanks
