As a PCF, how would I write exponential TSV21 crossing up through it's exponential moving average 12?

How would I write the exponential moving average 12 of Exponential TSV21 as an indicator?

Thank You!

Exponential TSV21:

XAVG(TSV,21)

Exponential TSV12:

XAVG(TSV,12)

EMA12 of Exponential TSV21 or EMA21 of Exponential TSV12 (both are the same):

(20 * XAVG(TSV,21) - 11 * XAVG(TSV,12)) / 9

Of interest in answering the question is that the Exponential TSV21 and Exponential TSV12 both cross up through the EMA12 of Exponential TSV21 or EMA21 of Exponential TSV12 at the same time.

Also of interest in answering the question is that this happens to be the point at which Exponential TSV12 crosses up through Exponential TSV21 (all three lines cross at the same point).

So the following Condition Formula is true both when Exponential TSV21 crosses up through its EMA12 and when Exponential TSV12 crosses up through its EMA21.

XAVG(TSV,12) > XAVG(TSV,21) AND XAVG(TSV1.1,12) <= XAVG(TSV1.1,21)

Cascades of Moving Averages

Sir, I thank you. I will admit. I had to read everything three times, but I wanted to understand thoroughly.  Cascades of Moving Averages is a nice touch,too. I will look forward to sharpening up.

You're welcome.
