This q only has to do with tech scans, not fundamentals or special N lists.

Is it possible to modify a variable somewhere in config files or whatever,
so that a tech scan will focus on a date prior to the last downloaded bar?

I don't want to have to modify the formulae.

Thanks

Could I please get some assistance with this? I'm holding up some of my work on account of it.

Thanks!

Follow these steps to enable OmniScan to store more historical technical data:

1. Close OmniTrader and Browse to C:\Documents and Settings\All Users\Application Data\Nirvana Systems. For Vista users it will be in the C:\Users\Public\Nirvana Systems folder.

2. Open the Nirvana.ini file.

3. Add a line just below [OmniScan] that reads NumBarsCached=500

The file will look similar to this:
[OmniData]
MaintenanceTimeouts=0
EasyToUser=True
LastAdminMsgId=4
LastAdminMsgDate=09/21/2006 00:00:00
Path=C:\Program Files\Nirvana\OmniData
[OmniScan]
NumBarsCached=500

4. Click Save and close the file.

5. Open OmniTrader and run your To Do List with Download OmniData and Update OmniScan checked. Note: It may take longer than usual since more data is being cached.

6. The technical criteria in your scan will also need to be edited. So while a current scan may look liks this...

MA_XOCOUNT(14,100) <= 60

a historical scan would like this:

MA_XOCOUNT(14,100)[250] <= 60

Hi, Barry:

Yep I know about that.

I'm asking about something different.

I want to be able to "set" OT so that OmniScan Technical filters (for that session) treats a PRIOR date as if it was the CURRENT date.

That is, if the most current download is 12/22/08, I want to be able to set OS Tech filters to work on, say, 12/05/08 data.

Is there a way to set a pointer to do this?

Yes, you can do that. In your ToDo List/Test Settings tab enable the Always Use this Date option & set the date to the current date that you would like to use. Then just rerun your ToDo List to update your scans.

Great! Much better than I'd hoped.
1. Will this prevent all formulae / indic's from "seeing" any info at all about following days?
2. Is this bar treated as HRE re tradeplan/chevron/voteline etc?
3. Does an OP "true walkfwd" run utilize this instead of or in addition to the system clockv

Thanks!

1. It should, but not many formulas have been tested.
2. Yes, it should.
3. Maybe, Matt is checking.

Currently OmniPilot uses either Lab Mode or the System Clock for the WalkForward tests. There is a feature request to have the methods for setting the FocusList Date publicly exposed within OmniPilot.

Thanks, Barry and Matthew.

It shore wud bee nise to get that feature request into the loop. One of the reasons I've avoided wf testing is I'm wary of the kludge to the system clock. Seems like other stuff might be messed up by that.

Have you had any problems reported, at all, re the sysclock-reset process?

Barry,

The setting "Always use this date" doesn't seems to have any effect on OT and OmniScan analysis results. They always correspond to the current date.
