Brief Description:
The Volume * Price Momentum Oscillator is a combination of price and volume indicators.
Definitions, Formulas:
As its name states, Volume * Price Momentum Oscillator (V*PMO) is both a price and volume momentum oscillator. To compute it we
First, calculate today’s V*PMO input value:
VTODAY * (CPTODAY – CPTODAY-1)
where
VTODAY = today’s volume
CPTODAY = today’s closing price
CPTODAY-1 = yesterday’s closing price
Then smooth the values using a 3-day exponential moving average (EMA):
V*PMO = EMA(3)(VTODAY,VTODAY-1,VTODAY-2)
Positive Development Calculation:
For this TAI, a new positive development (NPD) occurs when V*PMO crosses over zero. That is, when V*PMO x+ 0.
This TAI is no longer positive when V*PMO crosses under zero. In other words, when V*PMO x- 0.
If this TAI is still positive tomorrow it will no longer be new, but will be a Cumulative Positive Development (CPD)
“As with simple momentum indicators generally, when the n-period exponential moving average of V*PMO is positive, momentum is bullish, so we buy, entering or initiating a long position.”
========>any coding suggestions?

MAYBE...
updated with mri charting.... = )
needs to go to hundredths to work right???????????????
nope, something's not right, var6 can't be zero if var4 is below 0.....
the old, " must have 1 filtering line" requirement thing.......
still not right....
divide by a 1000???????????

Neat indicator!
How about adding a calculation to this so that when VAR 4 goes negative it charts to the bottom of the plot and when it goes positive it charts to the top of the plot? Maybe even color red for bottom and color green for top? :) A True / False plot
This instead of plotting VAR3 and VAR4.
Or, if the to zero line were plotted one could more easily see the switch?
Possible?
The guys that provide the coding on this forum are exceptional!!!

Gave it try on doing what I suggested. Can be improved I'm sure.

you all are very welcome. i see that springhill has the same problem as i did. i ended up having to do a "divide by 1000" to get a better response. i have updated the filter to plot your idea.
hth
enjoy

I find that if I draw only one side of the True/False that it eliminates a lot of the "noise" to look at.
change from
DRAW VAR6 ON PLOT VAR5
to
DRAW VAR5

IT IS STILL A TAD OFF. I THINK STOCKFETCHER HAS ISSUES WITH VERY BIG NUMBERS, THAT'S WHY MY DIVIDE BY A THOUSAND WORKS.

CHETRON---> made a few adjustments:
SET{VAR1,CLOSE 1 DAY AGO}
SET{VAR2,CLOSE - VAR1}
SET{VAR3,VOLUME * VAR2}
SET{VAR4a,CEMA(VAR3,3)}
set{car4,var4a / 1000}
set{NPD,count(car4 crossed over 0 from below,1)}
set{NND,count(car4 touch 0 from below and reverse,1)}
draw car4 on plot car3
add column car4
add column NPD
add column NND
---->BUT...cannot get "set{NND,count(car4 touch 0 from below and reverse,1)}" to work...looking for "car4" to touch 0(zero) and THEN reverse without crossing 0(zero)....can you code this?
