While applying pivotpointsall.efs to $SPX 1min and 5min charts.
If you compare the pivot point lines, you will find they are
difference. I found out the close values (vC) are different in this
two cases which results in the discrepency. Can somebody explain
why the close values are different in this two scenaria?

FWIW I am not seeing the differences you describe (see inline image below).

The efs I am using is downloaded from esignalcentral.
I am attaching the screenshots in this post and the next post. You can see the difference of pivot point values.

The 5min chart.

[eSignal_JasonK]

Hello clearpicks,

There was a bug found with Formulas/Pivots/PivotPointAll.efs related to the rawtime call on a 1-minute chart. Please try the updated formula: PivotPointAllnew.efs.

Regards,

[clearpicks]

still not correct

PivotPointsNew.efs is still buggy. During the trading hour, if you reload the pivotpointsnew.efs in $spx 1min chart, you will find the point points calculated changes every time you reload it. It seems it can not get the close price correctly. When the market is closed, the close prices won't change, thus the pivot points are of correct value. During the trading hour, if the pivotpoints.efs starts running before the market is open, then it is of no problem. But if it is opened after the market is open, then all pivot points are not correct. For all other intraday time frames, the same problem exists.

Hello clearpicks,

I've tested the reloading issue and I'm not experiencing the same behavior you are. I think the problem is external to the formula itself. Let's explore some other possibilities. For starters, what is the version and build number you are using (Help/About)? FYI, I was testing with 7.2 build 544.

Have you been running these pivot efs on existing charts in your layout?
If yes have you tried to create a new chart and run any of the pivot efs on
it to see if that changes anything?
You may also want to go into the eSignal folder and rename the Default.ach
file and then create a new chart in the application
Also I imagine that you are on East Coast time if your Time Template is
showing 9 :30-16:00 in the images you posted. Is that the case?
FWIW I ran the formula you posted yesterday and it was working fine here.

I am using 7.2 Build 544
I tried to new an advanced chart and apply pivotpointsnew.efs and still encounter the same problem.

Have you also tried renaming the default.ach file, then opening a new Adv
Chart in eSignal and running the efs on that new chart?
Another suggestion would be to post your Layout at FileShare in the eSignal
group so Jason or someone else can take a look at it..
To do this you would use the Publish Page to FileShare in the
eSignalCentral Toolbar.

After renaming default.ach, it seems work well. What is the usage of Default.ach?

[ACM]

clearpicks
Default.ach is the default chart that comes up whenever you load a new Advanced Chart.
It is possible that it got corrupted at some point with an earlier version and you were just carrying it over with every upgrade.
Anyhow you can now create your own default.ach.
Once you have set up a new chart to look the way you want, right click the chart and select Style Template-> Set as Default.
From then on every time you load a new Advanced Chart it will always come up with the settings you saved.
