I'm just trying to get a PCF for when the Exponential Stochastic 45,26,31 is in an uptrend or downtrend.  I know there's a ton of formulas already written but I'm only finding a very limited amount when i look.  I'd be grateful for  the formula, full library or both if you can.  Thanks in advance for all the great stuff.

There isn't a "complete library" of formulas available. The extreme variety of requests precludes the possibility of such a creation.

A formula for Stochastics being in an uptrend or downtrend would depend on your particular unambiguous definitions of uptrend and downtrend. Are you interested in Stochastics being below 20 or above 80? Are you interested in the SK or the SD? The SK crossing through the SD? Are you interested in the Net Change over some arbitrary period, the Linear Regression Slope over a period or something else entirely?

Sorry I realized I wasn't specific enough just as I sent it...When i use my formula library for STOC i get an option for Period and SK values.  I do not get an option for inputting the SD value.   For the Exponential Stochastic period45, SK 26, SD31 I need to know when the SK value is greater than the SD value or vice-versa.  I'm just not sure how to input the SD value.   Thanks again.

This is going to seem like it shouldn't work, but trust me, it does (it's simplified down from the longer, more obvious version of the formula):

Cascades of Moving Averages

Exponential Stochastic 45,26,31 SK above SD:

XAVG(STOC45,26) > XAVG(STOC45,31)

Exponential Stochastic 45,26,31 SK below SD:

XAVG(STOC45,26) < XAVG(STOC45,31)

The formula actually stays the same if you switch the periods of the SK and SD:

Exponential Stochastic 45,31,26 SK above SD:

XAVG(STOC45,26) > XAVG(STOC45,31)

Exponential Stochastic 45,31,26 SK below SD:

XAVG(STOC45,26) < XAVG(STOC45,31)
