Anonymous got a reaction from elqui in [VSA] Volume Spread Analysis Part I
There is more than one definition for No Demand.
In the book the base definition is given as a narrow spread bar closing up with volume less than the previous two bars.
The Trade guider definition, also in the book, is a narrow spread bar closing up on volume less than the previous two bars AND closing on the middle or low of its range.
Joel Pozen would define a No Demand as simply any bar closing up with volume less than the previous two bars. Or a bar closing equal, on volume less than the previous two bars with the previous bar higher than the bar two bars ago.
Still others would include any buying bar (a bar with a higher high, but not a lower low than the previous bar) that has a narrower range and with volume less than the previous two bars is No Demand. If it closes either up from or equal to the previous bar.
The underlying element is volume less than the previous two bars on equal or up closes. Note if the close is down and the we have a buying bar with the close on the low, the we have a hidden Upthrust in the form of No Demand.
Sorry, I don't think I have really answered your question. I guess the reason is, the question you should be asking yourself is "How am I comfortable defining No Demand within the context of market behavior and amidst the various possible elements set forth?".
I have added this beautiful pic from Monday. Note the two No Demands on the right of the Dotted line. The first one obviously closes on its high and has a smaller range than the previous bar. Plus it has volume less than the previous two bars and is a buying bar.
The second one has a greater range than the previous bar and closes near its low. It has volume less than the previous two bars. It is a buying bar (positional relationship), but the low closes signals no real buying going on. This is a Hidden UpThrust in the form of No Demand. TG software would NOT pick up either of these.
