Is there one time frame in which BOP gives a more accurate picture of what is going on? Sometimes the picture in the weekly vs. the daily time frames look absolutely contradictory. Is there a reason for this? Take a look at CSC. The weekly chart shows a solid red bar. The daily shows a bunch of kind of middling yellows. What gives?

The trainers can't give setting, interpretation or investment advice, but you may wish to review the following topics:
BOP values between Daily and Weekly charts
Discrepancy between representation of BOP in weekly and daily charts.

I came across a topic; Price Momentum Oscillator in information by Dr. Elder and would like to know what indicator it most closely aligns to in TC2000 or Worden speak?

I've tried to find information about a Price Momentum Oscillator developed by Dr. Elder on the internet without success.
What I have found is a proprietary indicator of this name by Decision Point.
The exact calculations are not given, but it is described as an EMA of a ratio based Rate of Change. The period of the EMA and ROC are not given. Their discussions of the indicator say it has the same shape as a MACD, but different values which are comparable between symbols.
Based on the above information, my best guess at something similar would be the Price Percent Oscillator (PPO) indicator.
Another option would be to add an Exponential Moving Average indicator to a Rate of Change (Percent) indicator.

Bruce, thanks for delving into the issue. I will work on your comments.
Regarding my last reply on mixed responses, it appeared on the screen that way but looks right now.
Thanks again!

I found this PMO description on Stockcharts.com. Hope this helps:
The DecisionPoint Price Momentum Oscillator is derived by taking a one day rate of change and smoothing it with two Exponential Moving Averages. The first EMA defaults to 35 periods and is multiplied by 10. It is then further smoothed by a second EMA which defaults to 20 periods.
PMO = 20 EMA (10 * 35 EMA(((Today's Price/Yesterday's Price)*100)-100))
Signal Line: 10 period EMA of PMO

If I'm understand the description correctly, an Indicator Formula for the PMO could be written as:

If you use the Indicator Formula for PMO as the Formula in a Custom PCF Indicator, you can add a 10-period exponential moving average to the Custom PCF Indicator to get the signal line. You would also probably want to click on the Custom PCF Indicator and select Horizontal Lines to add a line at 0.

Hi Bruce,
I am new to your service and i am currently using stockcharts and they have very good charts.
I want to calulcate the PMO(50,20,10) instead of PMO(35,20,10). I want to custom your formula but not sure how to replace 35 days with 50 days.
Please help me to design PMO(50,20,10).
Regards,
Nav

It is not particularly straightforward to replace the 35 with 50 in the formula. It uses techniques described in the Cascades of Moving Averages topic both to uncascade the moving averages and manually expand them to create formula with valid syntax.

With the added functionality in version 17 would it be possible to shorten the PMO code?

Yes, the PMO(35, 20, 10) can be written as follows.
1000 * XAVG(XAVG(C / C1 - 1, 34), 19)
And the PMO(50, 20, 10 Can be witten as follows.
1000 * XAVG(XAVG(C / C1 - 1, 49), 19)
