Close Positions after a CancelAllOrders() delay

[giogio1]

I need to do conceptually something like:

Order closeOrder;
​
int quantity = 10;

myAccount.CancelAllOrders(myInstrument);

sleep(xx);
​
closeOrder = myAccount.CreateOrder(myInstrument, OrderAction.Sell, OrderType.Market, OrderEntry.Automated, TimeInForce.Day, quantity, 0, 0, "myOCO", "closeOrder", Core.Globals.MaxDate, null);

myAccount.Submit(new[] { closeOrder });
​

The question is about the xx value.
Do I need to place a delay between canceling all orders and place a new order ?

Hello Gio,

For the NinjaTrader connection type, no, a delay would not be necessary.

For the Rithmic and Interactive Brokers connection types, a delay may be benificial.

We do not recommend sleeping any NinjaScript thread.

We instead recommend using a timer.

Attached is an example that paces order submissions, which you could adapt to cancellations and modifications as well.

Thank you Chelsea, your answer is very useful.
Without any responsibility on your part, and this is Rithmic stuff anyway, have you heard that in experience of others, 50ms delay is beneficial (just to throw a number) or 10mS might be sufficient? I'll go by trial and error, but maybe you have an idea what a good number might work generally ok.

Hello G,

Unfortunately, I haven't had any feed back on this.

I would like to know if this is particularly effective and at what delay.

Please assign enableDebuggingPrints a value of true on line 118, then test assigning the timerInterval on line 121 values of 1ms, 2ms, 3ms, 5ms, etc, until the behavior can be avoided or until 50ms.
Each time the code is changed and compiled, the addon window will need to be closed and a new window opened from the New menu > Account Order Examples > Pace Trade Copy Addon Example.
Please report back and provide the output from the output window produced by the script saved to a text file (right-click the output window.
