OCO order is accepted by NinjaTrader, but is cancelled right away.

[techsigma]

I am trying to send an order with an additional two as a Target and Stop order. The original purchase executed perfectly. The others execute without an error but are canceled by NinjaTrader:

Client myClient = new Client();
int connect = myClient.Connected(1);

Decimal StockPrice = (Decimal)getPrice;
Decimal TakeProfit = StockPrice + (1.40M * ADR); ;
Decimal StopLoss = StockPrice - ADR;

DateTime foo = DateTime.Now;
long unixTime = ((DateTimeOffset)foo).ToUnixTimeSeconds(); //Ensures that an original OCOID is always generated

//Original Price
int mainPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "BUY", 1, "MARKET", 0, 0, "GTC", unixTime.ToString(), "", "", "");

//Take Profit Order
int takeProfitPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "SELL", 1, "LIMIT", (double)TakeProfit, 0, "GTC", unixTime.ToString(), "", "", "");

//Stop Loss Order
int stopLossPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "SELL", 1, "STOPMARKET", 0, (double)StopLoss, "GTC", unixTime.ToString(), "", "", "");

Hello techsigma,

Thanks for your post.

We are unable to reproduce the behavior you are reporting when testing submitting two orders tied by an OCO ID.

Please see the video linked below demonstrating sending a Stop Market order and Limit order tied by an OCO ID.

Do you see that a cancellation request is being sent in the Log tab of the Control Center?

Is there an order being rejected?

Could you tell us more about what you are doing to place the orders?

I look forward to further assisting.

Hello, a follow up on this topic - is it possible to submit 2 OCO orders using same approach you have shown in video - but both of these orders would have different order quantity? For example, I want to have "Stop" and "Target" orders linked through OCO. Then I want to scale in into position, and as my position size increases - I want to update existing two "OCO" orders with the new quantity. Is it possible to do? Could you demonstrate using your tool to submit and then modify these two orders with different quantities while retaining original OCO ID?

Also Brandon, wondering if you could share your small utility / VS solution so that I could also perform some tests there...

Thanks a lot!

Hello music_p13,

Thanks for your note.

It is likely that it would be possible to submit 2 OCO orders and have each order have a different order quantity.

Support for the API is limited. We would be able to submit bug reports for any incorrect behavior. We are not able to assist with any code in an application external to NinjaTrader.

Below I am providing a publicly available link to the help guide that lists the functions available to the API.
Help Guide NT8 API functions - http://ninjatrader.com/support/helpG..._interface.htm

Please also refer to this forum post link for more information about the NinjaTrader API — https://ninjatrader.com/support/foru...art#post793626

Note that the script used in my demonstration video is an internal script used for testing purposes and this script cannot be shared publicly.

This thread will be open for other developers in the community to share their insight if anyone has tips for external application code.

Let us know if we may assist further.

Thanks for the prompt reply. I placed 3 orders. The original purchase at market price. Then, the take profit and subsequent stop loss orders. I do this without using ATM Strategy because my trading rules use ATR, and I don't see a quick way of doing that through ATM Strategy. So, I use a C# program that has it internal algorithm to calculate all that, and then throw 3 orders to Ninja trader as seen below. The orders are not being rejected. They are received without a hitch, except for the cancellation of the SL and TP orders.


This one below is the market order.
int mainPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "BUY", 1, "MARKET", 0, 0, "GTC", unixTime.ToString(), unixTime.ToString() + "-1", "", "");

I set the a limit order for the take profit
//Take Profit Order
int takeProfitPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "SELL", 1, "LIMIT", (double)TakeProfit, 0, "GTC", unixTime.ToString(), unixTime.ToString() + "-1", "", "");

Stopmarket order for the stop loss
//Stop Loss Order
int stopLossPosition = myClient.Command("PLACE", "Sim101", "MNQ 03-22", "SELL", 1, "STOPMARKET", 0, (double)StopLoss, "GTC", unixTime.ToString(), unixTime.ToString() + "-1", "", "");

Maybe would you mind sending me your code? I think maybe what I am doing wrong is sending the stop loss and take profit orders under the same order as the original. In your video, I only saw two.

As per the log, here is the information that it has:

OK...can you at least tell me why the OCO orders are cancelled by Ninja Trader?

[NinjaTrader_BrandonH]

Hello techsigma,

Thanks for your note.

I am unable to determine why the orders are being canceled without testing and debugging the script.

That said, to understand how orders are being placed and how the script is behaving, you would need to take debugging steps.

Below is a link to a forum post that demonstrates debugging to understand the behavior of a script.
