Hello svopex,

To clarify, you have added multiple data series to your script. Are you asking which BarsInProgress will trigger on each bar that closes at the same time?

Answer ...

Hello Chelsea B., no

. Sorry for my bad English.

NinjaTrader, by my opinion, run OnBarUpdate() in same time (in same candle) for more strategies serially, not paraell.
Ninjatrader don't use multitasking.

For example, i have two strategy:

class strategy1: Strategy
{
void OnBarUpdate(...)
{
...
}
}

class strategy2: Strategy
{
void OnBarUpdate(...)
{
...
}
}

And NinjaTrader run it (for eample on 15 minutes candles):

...
...
...

Candle 16:15
===========
16:15:00 strategy1->OnBarUpdate(...)
16:15:02 strategy2->OnBarUpdate(...)

Description:
strategy2->OnBarUpdate() run after strategy1->OnBarUpdate() stopped...

Candle 16:30
===========
16:30:00 strategy1->OnBarUpdate(...)
16:30:03 strategy2->OnBarUpdate(...)

Description:
strategy2->OnBarUpdate() run after strategy1->OnBarUpdate() stopped...

...
...
...

And i want to NinjaTrader run strategies (OnBarUpdate(...) function) paraelly (as multitasking, for example windows have multitasking, MSDOS haven't multitasking) in same candle time:

Candle 16:15
===========
16:15:00 strategy1->OnBarUpdate(...) ... 16:15:00 strategy2->OnBarUpdate(...)

Candle 16:30
===========
16:30:00 strategy1->OnBarUpdate(...) ... 16:30:00 strategy2->OnBarUpdate(...)

Candle 16:45
===========
16:45:00 strategy1->OnBarUpdate(...) ... 16:45:00 strategy2->OnBarUpdate(...)

Can you enable this feature in NinjaTrader?
Or support this feature NinjaTrader 8?

Thanks for answer Petr

Hello svopex,

NinjaScripts and the NinjaTrader UI all run in one thread. NinjaTrader 7 is not a multi-threaded application.

NinjaTrader 8 is designed as a multi-threaded application. Each chart will run in its own thread.

Below is a link to a list of Major Enhancements for NinjaTrader 8.
http://www.ninjatrader.com/downloads...njaTrader8.pdf

However, it is not confirmed if multiple strategies running on a chart will be in one thread or if strategies added without charts.

If I find more information about this I will post in this thread (bookmarking).

Super.

Can I participate on the beta version of Ninja trader 8 testing?

Petr

Hello Petr,

Please send an email to platformsupport [at] ninjatrader [dot] com requesting to be added to the NinjaTrader 8 Beta.

Right now the beta is limited to a small group but that group will expand. I cannot say for sure if you will be chosen for the beta but we can add you to the list.

**NinjaTrader_ChelseaB** · 05-21-2015, 02:55 PM

Hello svopex,

I've got a little more information for you.

All strategies will be run in the Control Center thread.

When opening a new chart, all indicators started on that chart will run in the same thread as that chart.

All events such as OnMarketData, OnMarketDepth, etc are run in a background service thread.

If you add a strategy to a chart that also adds indicators to the chart, the strategy will be run in the Control Center thread while all the indicators will be run in the thread of the chart.

**svopex** · 05-21-2015, 11:40 PM

Thanks for detailed information, but I must wait to NinjaTrader 8 :-).

You write:

I have additional question.

Is this correct?
- strategies without chart are run as multithreading
- multiple charts, one strategy in one chart, this is run as multithreading
- multiple strategies in one chart: ???

Is multiple strategies in one chart run as multithreading?

Thank you for answer.

Thank you for your note.

Each object will run on the thread it is started from. So each strategy on the Strategies tab would be ran on that one thread.

To clarify my response, this is for NinjaTrader 8. NinjaTrader 7 all objects would be on one thread.
