Question regarding computing core utilization when displaying historical charts

[h1000]

I’m trying to better understand how NinjaTrader utilizes computing cores and came across this post which was quite useful. Quoting from a post (https://ninjatrader.com/support/foru...57#post1076757), NinjaTrader_PatrickG stated:

NinjaTrader 8 is multi-threaded and can, in theory, utilize all available cores of your processor. With that said, depending on how you're using NinjaTrader, you may be bottle-necking a thread. One core concept that is important to understand about NinjaTrader's multi-threaded design is that each instrument is assigned to a thread and all windows with that instrument will run on that same thread. This is done so that an instrument cannot become out of sync with itself. Here is a simplified example:

10 charts with 10 separate instruments = 10 threads.
10 charts with 1 instrument in all charts = 1 thread

I often use NinjaTrader in offline mode to study and screen stocks. Generally, I connect to a BarChart datafeed and download 4-5 months of day and one minute data of 50 to 100 stocks. I then disconnect from the data feed and using the downloaded data, create 2 charts:
1 day chart (5 months of data)
1 30-minute chart (5 months of data)
Both charts display the same instrument.

When not processing realtime data, does NinjaTrader still use the one thread / one instrument setup as described in the post by NinjaTrader_PatrickG?

Hello h1000,

When running on charts, NinjaTrader will still request data for each instrument and then the data will be provided to the instrument consumer threads.

Things work a little differently when optimizing, but still work the same when loading historical data on charts.

ChelseaB, thanks for the clarification!
