I do not see the PoC (or its equivalent) to judge the skew in your charts.

JPerl gave the Shapiro as a very basic filter for judging direction. We can use that or whatever we are confident about. This flexibility is what makes Jperl's Market Stats approach absolutely brilliant.

Indeed. As Jose points out it is a simple price pattern that shows that price has changed direction (though I'd be inclined to call it a trigger rather than a filter). It's kind of similar to what old timers would have called a key reversal. You could substitute anything that indicated that price had been rejected or supply/demand had shifted at a market stats derived level.

I don't think this question has ever really been answered specifically but I apologize if it was. I may be a bit behind in some responses but don't see this one addressed well. No offense to Jpearl as this threads really rocks.

For example: Jerry has mentioned to use a 5 day period but what do we do when Monday morning comes around or we start any new day ? Do we drop off the oldest day as the new day begins ? This would then have only 4 completed days and then the start of the current day...so that isn't a complete 5 day period until we finish that days worth of trading. Dropping data might also affect where VWAP now is or the PVP ! So that would mess up the concept of the skew.

We can apply the same concept to a 10 day or twenty day period. Really any period of time. Dropping data may change the skew, vwap and PVP. If all of this has been addressed then please tell me where so I don't waste the forums time. We can't say that it doesn't matter when we start or stop the time frame unless we are in agreement that the concept of skew doesn't matter.

Hopefully someone can shed some light here or point me in the right direction so I can do further research. Thanks
