Using an indicator to run an external program if orders and market position is flat

[paulbishy]

I have an indicator which runs an external bat file on each bar close using Process.Start. This part works ok.

But I only want the Process.Start command to run if there are no pending orders and the market position is flat.

I tried as below but get "Error on calling 'OnBarUpdate' method on bar 6304: Object reference not set to an instance of an object."

//Add your custom indicator logic here.
if(State == State.Historical)
return;
if (accountPosition.MarketPosition == MarketPosition.Flat)
{
//Print(string.Format("{0} accountPosition.MarketPosition"));
Process.Start(@"C:\Users\paulb\Documents\MyNTstuff \runmacro.bat");
}


Thanks

Hello paulbishy,

Has accountPosition been assigned a position object?

[paulbishy]

Hi Chelsea B.

Thanks for prompt reply.

Im no C# programmer but im sure its something relatively simple.

Do you mean this ?

public class barcloserunmacrobat_withOrder : Indicator
{
private Position accountPosition;
private List<Order> changeOrdersArray, submitOrdersArray;
private double currentPtPrice, currentSlPrice;
private Order entryBuyMar****rder, profitTargetOrder, stopLossOrder;
private Account submissionAccount;


Thanks

Hello Paul,

You need an account object assigned to the variable.

Below is a link to the help guide.

Hi Chelsea,

Happy New Year, hope you had a good break.

Due to work commitments and Xmas I am having another look at trying to get this working.

At the end of the day, I just want the line "Process.Start(@"C:\Users\paulb\Documents\MyNTstuf f \runmacro.bat");" to run of the account is flat or there are no orders.

How can I get a complete indicator written with the above logic ?

Thanks
Paul

Hello Paul,

This is a dos command line to run a batch script. Far outside of what is supported by NinjaTrader.

What do you want to do?

Are you trying to trigger some action when you click a button in an addon window in NinjaTrader?

Previously you were asking about an accountPosition variable.

You needed to find an account and assign that to a variable, then find the account.Position. Did you get that part worked out?

[paulbishy]

Hi Chelsea,

The dos command part works fine.

I just need to check before the dos command so that the dos command doesnt run if the account has open orders or is already in a position

I cannot get the account.Position to work. Dos command always runs

Something like this:

If account.Position equal to flat and no open orders
then
run dos command
end

Paul,

I would not be able assist with the dos command.

Lets focus on the account.

Previously you were asking about an accountPosition variable.

You needed to find an account and assign that to a variable, then find the account.Position. Did you get that part worked out?

[paulbishy]

Hi Chelsea,

Understood.

No, I have not been able to get the account.Position to work.

Is there any complete template indicator which you can provide which provides the account.Position ?
I can then place the dos command after this.

Thanks
Paul

Hello Paul,

By template do you mean a NinjaScript example?

I am going to assume you are not looking for an actual chart template or script template file.

Below is a link to an example indicator that assigns a Account object to an Account variable. (ProfitChaseStopTrailIndicatorExample_NT8)

Thanks Chelsea

I have added Orders and Account object but still struggling to get the logice together to check if there any open Orders or Positions.

Any help appreciated

Thanks

Hello Paul,

Once you have an account assigned to a variable, loop through the <Account>.Orders.

Below is a link to the help guide on <Account>.Orders which includes a code sample.
https://ninjatrader.com/support/help...rs_account.htm

Below is a link to the help guide for the Order object.
https://ninjatrader.com/support/help.../nt8/order.htm

If the <Order>.OrderState is OrderState.Working or the <Order>.OrderState is OrderState.Accepted, then you know the order is working.

foreach (Order order in myAccount.Orders)
{
    if (order.OrderState == OrderState.Working || order.OrderState == OrderState.Accepted)
   {
      // this order is a working order. change a bool to true, assign the order to a variable, or take the action you would like to take when finding a working order.
   }
}​

Loop through the <Account>.Positions.

Below is a link to the help guide on <Account>.Positions which includes a code sample.
https://ninjatrader.com/support/help...ns_account.htm

Below is a link to the help guide on the Position object.
https://ninjatrader.com/support/help...8/position.htm

If the <Position>.MarketPosition is not MarketPosition.Flat, the position is open and is either long or short.

Hi Chelsea,

Many thanks for your support, I now have the logic working.

But I now have a 2nd query.

Im using the playback tool to testout my indicator but I need the playback to pause momenteraly while my indicator makes some calculations and then playback to continue once the indicator has completed its calculations.
Is this possible ?

Thanks
Paul

[NinjaTrader_ChelseaB]

Hello Paul,

Hit the pause button on the Playback controller.

If you are asking if you can control playback through code, there would not be a supported method for this.
