Post From: VbP: Include Prior Profile Common Price Volume

I've thought about this more and experimented with various overlaid VbP studies - and I think what really is of value here is not necessarily including the previous profile as a binary option but the general aspect of "period" vs "frequency" in the general VbP settings. On top of that, start and end (period) could have the concept of where start actually is and if it's an absolute window vs a moving/shifting window. Default for frequency could be 0 which is a sentinel value for "same as period" as it functions now. Examples: Period: 7 day Frequency: 1 day Window: Absolute The above would plot a 7 day VbP at daily boundaries taking into account the entire cumulative period, essentially showing a weekly VbP being built up each day (with the 1st day starting at zero). Period: 7 day Frequency: 1 day Window: Moving The above would plot a 7 day VbP at daily boundaries but the 7 days is 7 days of cumulative volume from the point of plot and back, not 7 absolute days from the beginning of the period (which could be totally empty if it just started). As each day progresses the new 7 day VbP will plot, but will consider 7 days back rather than something being built up over 7 days. This is a rolling 7 day VbP plotted daily. Period: 2 day Frequency: 1 day Window: Moving The above is the same as the previous example, but the rolling window is 2 days. This accomplishes the same goal as "include prior profile" as does anything else using a rolling window type. The ability to plot VbPs of a given period on a different frequency from the period itself *and* also have the ability to calculate cumulative volume on a rolling period rather than an absolute period would be a pretty kick ass feature as it would take into account previous period volumes. This is similar to how the last days highs and lows are relevant to the current day. Right now, at the end of a period, one can do something *similar* by looking at the previous period's VbP and marking in the future where a given area of interest may be - but the new period they're operating with will be entirely empty at the beginning meaning in most cases the previous profile will end up having to be consulted anyway just to figure out potentially where things may go. Visible bars is already automatically doing a lot of what I'm describing but it's entirely dependent on what is visible and cannot show change over time (frequency of when the period is plotted) because it takes into account everything that's viewable. Frequency and window type are the additional dimensions here. Date Time Of Last Edit: 2015-03-29 22:39:40
