Volume indicator

[Rustie]

Would it be possible to have the scaling of the volume indicator the same as an advanced chart?

When I get a huge volume spike all other vol bars are unreadable and if I manually rescale larger all the bars disapear under the viewable section of the volume box, under the screen.

Cheers

I agree with you 100%. It's a real pain. The function is
in the y-axis of the Advanced Chart. It would seem so
simple to apply it to the volume scale, and make eSignal
charts just that much better. I wrote to [email protected] suggesting this about a year ago. You may want give it
a try too.

Hey guys, don't hold your breath waiting for this one. It's been requested for many years, by many people, here, through Ideas and via the EliteTrader forum.

BKuerbs developed an EFS for volume spike filtering back in May, 2004 http://forum.esignalcentral.com/show...t=volume+spike that may help you.

Alex also recommended that EFS and I have been using it
ever since(thanks again Alex). It's ok, but a far cry from what eSignal could provide. They've created so many wonderful and complicated functions, and I just can't understand why they have skipped this very basic one.

Vol EFS

Cheers, Thanks for that! Something so simple hey.

Just wondering about the settings for the EFS.
What does the factor setting do?
And how does it relate to the MA length?

The Factor parameter increases/decreases the spike "clipping" sensitivity. This is based on a moving average which is used to determine the sample data.
Attached is a similar script that instead of using a moving average it bases its calculations on the regression of all the historical volume data. I believe this method is somewhat similar to that used in some other charting packages such as for example QCharts. The default value for the factor is set to 2 which should function in most conditions (lower values increase the clipping while higher values decrease the clipping). Also included is a manual override which allows the user to set a specific Volume clipping value
In the first chart enclosed below you can see the regular Volume study (in the top pane) compared to the one plotted by the efs.
In the second chart the same symbol is plotted in Qcharts with and without the Volume clipping which is based on RMS (root mean square) of Volume

I have replaced B Kuerbs' volume autoclipv6.efs with your
volume(clip).efs having found it to be preferable mainly due
to its manual override function.

Thak you very much for this EFS.

The Volume EFS works great. But is there a way to delete
the title? The reason is that on a small chart the title and
the following numbers reach across to the y-axis
making it hard sometimes to read the most recent volume
bars.

Thank you,

To prevent displaying the parameter list in the study title add the following statement in the preMain function of the efs
setShowTitleParameters(false);
Alternatively you can right click the chart, select Properties and uncheck the Draw Study Titles option. Note that this will remove the study titles of all the studies loaded in a chart.
