Is there a way to save a repository of Realcode code without putting
them on a chart. For example I would like to create a set of
conditions for candlestick formations, but I don't want to put them on a chart.
Is there a way to suspend calcuation of a Realcode condition that I
have on the chart. I don't want to remove it, I just want it to not
calculate for a while.
How can I speed up my filtering and sorting? My cpu and memory are
not being used that much but filtering is very slow.
I notice the "Force Memory Reduction" option in the downloader.
Is there another one to Force Memory Increase?
Blocks on "Data Status" up on top says my daily is "Not connected" although RT is getting updated.
Is that right?
Thanks for any help you can provide.

1. Not currently vasm. But this is coming.
2. Click once on the condition and set the update frequency to 1 Hour. Currently, that's the maximum. When the ability to save conditions gets added (part of item 1 above), you can just remove it from the chart and re-add it later.
3. I'd need more info on what, exactly, you are sorting and fitering by, what list, etc.
4. It shouldn't say 'Not Connected' if it is indeed connected. Don't know about that one.

Thanks for responding.
With respect to point 3:
The Realcode condition I'm using is
'# Stoc21 = indicator.Stochastics.4
'# Stoc5 = indicator.Stochastics.5
If Stoc21.value <= 30 And Stoc5.value >= 70 Then pass
Stoc 21 refers to a 21 period stochastics and Stoc5 refers to a 5 period stochastics.
On a 15 min timeframe on the S&P 500 component list it took 8 mins and 28 seconds.
I did a second trial and on that run it took about 8' 10", about the same.
This is the only filter on the watchlist and there are no sorts.
On Vista's Task Manager, it says BlocksHost is using about 35% of CPU and ~530 Meg of memory.
Any hints or recos on how to speed this up would be greatly appreciated.
I see great potential uses for Blocks once I get over some of these issues.

Took about 1 minute to filter the SP-500 list using the same RealCode condition. I'm running a 2.66 GHz Core Duo with 4GB RAM, Vista Ultimate.

Filtering on time frames less than a minute are going to be more related to your hard drive speed than anything. Do you perhaps have the minute data on an external drive? This would really make it slow. You can also change the limit for the number of bars below daily and that may help also.

Thanks for the reply guys. Nice to hear that it's taking much less time for you.
It implies there is some hope for me to get this working in real time.
Just FYI, I'm running the scans on a new Toshiba laptop I bought last week.
Belarc tells me I'm running a 1.67 GHz Core2Duo with 2 Gig or RAM.
I don't have an external drive, but I presume the hard disk speed is a bit slower because it's a laptop drive.
testOP2, thanks. I'll try limiting the Update Frequencies to see if that speeds things up.

Click Settings | Data Manager and lower the intraday bar limit as testOP2 suggested. See if that helps.
