Creating superposition inside indicator

[Karish]

According help I think that managedseries is the correct tool as compressSeries does not support superposition, but then it seems that there is no way to make use of the superposition but build the series from scratch, is it correct?

[Bruce DeVault]

That is correct - in the current 4.2 NeoTicker architecture you would use SetManagedSeries for this task.

Thx, seems I have some work in front of me.

Take a look at this blog article http://newsletter.neoticker.com/2006...nt-and-figure/ for a good example to get started. Good luck, and keep us posted!

Thx, I use this post as basis for my work

Once I create the higher time frame from the input link, there is no more need to store it and I want to release its memory. Is it possible to reduce the conserved memory of Link 1 using the data manager > conserve memory > limit # of bars? What does it actually limit? the total of bars on the window, of the first link, all links? is it useful at all?

[Bruce DeVault]

Could you be more specific please about what setting you are referring to? Are you referring to IQFeed? If so, the limitation would be on the number of historical bars you can retrieve to backfill your disk cache, and would not otherwise affect indicator operation.

[Karish]

I am referring to long history back testing were all data resides in disk cache. I load a chart with 1Sec. bars and create internally several series, once the internal series is created the 1sec. is redundant and I would like to limit it's memory usage. Now, In Chart Manager under data Setting we can setup the chart to a fix # of bars. My question what this fix number effects, will it limit this 1Sec. link only, if I have additional links to this indicator would lit limit them to this number too?
Thx

[Bruce DeVault]

Limiting the chart to a fixed number of bars will limit the number of bars loaded initially on the chart, and therefore the number of bars tracked on any series such as those in indicators that are created initially as well, because those have one value tracked for each bar on the chart.

The conserve memory setting apply to all data series loaded in the current chart.

[Karish]

Thank you both,

Did some usability test and..
Unfortunately, this setup is maybe useful for live system, however most of the time were memory is under stress is during long period of historical tests.
As a chart is loaded sequentially first data than indicators this feature cannot be used.

Please correct me if my observation is wrong.

[Bruce DeVault]

There's nothing wrong with the setting - it works as it is supposed to, and limits the number of bars initially loaded as I described above. It you need more bars than this, of course, you would have to not limit it or set the limit higher, but it definitely limits to the number you specify.

It sounds like you are saying what you want is for NeoTicker not to keep all past bars in memory as it's running - that's a topic that has been discussed and that TickQuest has said they are working on for future releases.
