Quote from dandxg:
Just to expound on the PV discussion, and with all due respect to Prof Logic. If volume bar are superior, then why did Wyckoff use time bars? Were they not available? Most likely? I am just starting to learn about him. He is the PV genius himself correct? The one that started all of this?
Constant volume bars are not superior. The problem with constant volume bars is that: all the bars have constant volume.

There is no way to determine the activity on one bar with the previous bar or any other bar as the volume remains the same. Time helps but it is not sufficient for seeing where the Smart Money is. Or more precisely, what the Smart Money is doing.
The following chart is of the Euro today after the Jobs report.
While there is a CCI 6 on top of the chart, it is not used in analyzing the market. ONLY PRICE AND VOLUME is used. BTW, for those interested, this template is based on the template from Tradingmentor (.net). I am in no way recommending the course however. Joel Pozen does do an impressive job of reading price/volume in real time during the demo. The skills can be learned through Tom's book
Master the Markets and some screen time. Tradeguider free webinars are also a major help.
Anyway. let's take a look at the Euro.
1. Black arrows point to the bar and corresponding volume at 0830. Notice how price jumps up on a wide range with high volume, closes above the "pivot"-white dashed line, and closes off the high.
VSA teaches that markets do not like wide spread bars on high or ultra high volume that close up. Why? Because there could be hidden selling in the bar.
2. Next bar is a classic sign of Professional activity. The bar is wide spread with ultra high volume that closes in the middle of its range. If this bar represented buying, then the close should not be in the middle of the range, it should be on the high. Hence we see Supply (selling) being dumped on the market at this bar. The previous bar too had some selling. Note that the bar closes just above R1.
3. Next bar makes a higher high, but closes near its low on even higher volume. Professional money is selling into this bar. Some would call this a "buying bar" because it has a higher high than the previous bar and a lower or equal low. But in truth, supply (Selling) is swamping demand (buying) on this bar.
4. Check out the bar one back from the bar with the red arrow. This is a narrow range bar with volume less than the previous two bars and it closes in its upper range. The bar also closes up from the previous day. The lack of volume as price rises shows that there is no Professional desire to take prices higher. The narrow range tells us that the market makers are keeping the range small as they expect price to fall. They also see large sell orders on the books from the Smart Money. Retail traders looking to get long, think they are getting a good price. NOT.
5. This is an Up-thrust. The range is greater than the previous bar, it makes a higher high, closes on or near its low, and the volume is less than the previous two bars. The Smart Money marks price up to suck in some late longs, and then price ends near its low. Note how the high moves price above R1. On the close of this bar, with signs of supply in the background, a short entry is taken.
If volume remains constant from bar to bar, there is no way to determine the true intentions of the Professional traders. Reading a chart means looking at least three dimensions: Volume, Price (close), and Spread (range). The fourth would be the open, but Tom Williams doesn't look at it. His one-time student Joel does. Joel also studied under Richard Ney.
