enabling Strategy on strategy page

[richbois]

In NT 7 we used to be able to enable a strategy on the strategy page

This feature is not available in NT8

Hello richbois,

Sorry, I am not sure if I understand. You can enable automated strategies in the Control Center-->Strategies in NinjaTrader 8. Your screenshot shows the Strategies-tab with a strategy enabled.

Can you please test the SampleMACrossOver strategy on the Sim101 account. Once you checked the Enabled box, please check if you see the strategy is enabled in the Control Center-->Log-tab.

ok what i was trying to say is when i start NT8 then connect to data supplier then go to Strategy page to enable the strategy i was not able to enable it there

now i added your Sample Crossover to the chart and restarted NT8. I was able to enable it from the Strategy page but not my own created strategy. The error message on the output window is

Error on calling 'OnStateChange' method: The calling thread cannot access this object because a different thread owns it.

so I guess there is something wrong in my script

Thank you for your help

Hello richbois,

Thanks for your reply.

To verify, when you are connected to the market, please go to the strategies tab in the control center and right mouse click in the strategy tab, next in the context menu select "new Strategy", then in the strategies tab select the strategy SampleMACrossover, select the instrument to apply to at the top then click OK, at that point can you click the enable check box in the strategies tab. Does it enable? Do you see any error messages in this process?

If the above process works without errors on the sampleMaCrossover strategy, please remove your strategy from any charts (to isolate), and repeat the above process but this time with your strategy. Does it enable? Do you see any error messages?

For reference, here is a link to the strategies tab helpguide: http://ninjatrader.com/support/helpG...tegies_tab.htm

yes Paul all is good with SampleMAcrossover

I only get this error after boot up with my strategy not your sample.

There must be something in my script that cause this error

this is the part that is referred to in the error

#region OnStateChange
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"OilHawk system";
Name = "OilHawk";
Calculate = Calculate.OnEachTick;
IsOverlay = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
EntriesPerDirection = 1;
EntryHandling = EntryHandling.AllEntries;
IsExitOnSessionCloseStrategy = true;
ExitOnSessionCloseSeconds = 60;
IsFillLimitOnTouch = true;
MaximumBarsLookBack = MaximumBarsLookBack.Infinite;
OrderFillResolution = OrderFillResolution.Standard;
Slippage = 0;
StartBehavior = StartBehavior.WaitUntilFlat;
TimeInForce = TimeInForce.Day;
TraceOrders = false;
RealtimeErrorHandling = RealtimeErrorHandling.StopCancelClose;
StopTargetHandling = StopTargetHandling.PerEntryExecution;
BarsRequiredToTrade = 20;


}
else if (State == State.Configure)
{
}
else if (State == State.Historical)
{
//Call Our AddToolBarButton Method - Latching Bool used to Assure this is Executed Only Once!
if(!IsToolBarButtonAdded) AddToolBarButton();
}
else if (State == State.Terminated)
{
//Call Our DisposeMyStuff Method - and Dispose of Anything Needing Disposed of on Termination
DisposeMyStuff();
}
}
#endregion


any ideas

again thanks in advance

PS once enable manually then i can disable and enable in the Strategy tab

Hello richbois,

Thanks for your reply and clarity.

To debug you could add Print statements in each state to see how far you are getting. For debugging purposes you could also comment out the toolbar statement, then the dispose statement to try an isolate the issue.

[richbois]

you are correct the toolbar is the issue

// else if (State == State.Historical)
// {
// //Call Our AddToolBarButton Method - Latching Bool used to Assure this is Executed Only Once!
// if(!IsToolBarButtonAdded) AddToolBarButton();
// }


can you see what is wrong with it

Hello richbois,

Thanks for your reply.

At this level would be impossible to say. If you like you can send in your complete strategy and we can test here. If that is of interest, send to Platformsupport[at]Ninjatrader[dot]com with Atten: Paul && enabling Strategy on strategy page. If you send it in, please do include the step by step process you used to generate the error.

[richbois]

this is a very similar strategy that gives me the same issue

This was developed on this thread

http://ninjatrader.com/support/forum/showthread.php?p=429537#post429537

I also include the script for it

step by step

Insert Buttons on chart
Close NT8
Start NT8
Connect
goto strategy page and try to enable it should not

However if you go to chart and enable chart manually then it will enable]

then you can go to Strategy page and disable enable no problem


so the issue is when you start NT and go to Strategy page to enable

[NinjaTrader_Brett]

To resolve please see my modifications attached. The reason this is occurring is sense the strategy is owned by the chart when enabled on the chart, else when enabled on the control center it was owned by the control center.

We will look into normalizing the 'this.Dispatcher' to always be the dispatcher of the chart for next release if it is possible and prudent to do so.

great Bret that worked
