Multi-threading and SubmitOrder

[cls71]

Hello,
I want to submit an entry order on a secundary thread, but does not work and Ninjatrader is frozen.
Is there any internal lock inside SubmitOrder() ?
If I replace the function "SubmitOrder" by "Print" works well. So I suspect there is some internal lock. Could you confirm this point?.
Thanks very much.

using System.Threading;
using NinjaTrader.Cbi;
using NinjaTrader.Data;
using NinjaTrader.Indicator;
using NinjaTrader.Gui.Chart;
using NinjaTrader.Strategy;

namespace NinjaTrader.Strategy
{
    public class Zs7Borrar01 : Strategy
    {
	private bool done = false;

        protected override void Initialize()
        {
		Unmanaged = true;
           	CalculateOnBarClose = true;
        }

        protected override void OnBarUpdate()
        {
		if ( !Historical && !done )
		{
			Thread ts = new Thread(threadSubmitEntryOrder);
			ts.Start();
			ts.Join();
			done = true;
		}
        }
		
	private void threadSubmitEntryOrder()
	{
		IOrder o = SubmitOrder( 0, OrderAction.Buy, OrderType.Market, 1, 0.0, 0.0, string.Empty, "Compra" );
	}
    }
}

Hello,

To work in new thread you need to send current "engine" to that. Example code:

protected override void OnBarUpdate()
{
if ( !Historical && !done )
{
Thread ts = new Thread(threadSubmitEntryOrder);
ts.Start(this);
done = true;
}
}

private void threadSubmitEntryOrder(object data)
{
StrategyBase strategy = data as StrategyBase;


IOrder o = stategy.SubmitOrder( 0, OrderAction.Buy, OrderType.Market, 1, 0.0, 0.0, string.Empty, "Compra" );
}

Thanks Mikha, but still not working. NinjaTrader is frozen.

With StrategyBase.Print() works correctly, but not with StrategyBase.SubmitOrder(). I think there is some internal lock.

Hello cls71,

While running in real-time data, NinjaTrader will have the incoming data on a single thread and it will process the NinjaScript/Order submissions on another thread. Unfortunately, submitting an order an a different thread other than the one intended would not be supported.
