Hello laketrader,

OCO is only a programming task in the unmanaged approach, in the managed approach you use signal names. You can find an example that uses OCO strings here: https://ninjatrader.com/support/foru...926#post486926

Hi Jesse,

Thank you for the quick response. I updated with UnmanagedOCOBracketExample.cs with onBarUpdate with the code from SampleMACrossover strategy. And it worked great. But I tried to put the same code in a NT8 addon. I got " Object reference not set to an instance of an object." error when I put the follwing statement:
SubmitOrderUnmanaged(0, OrderAction.Buy, OrderType.Market, 1, 0, 0, "", "longStopEntry");

Is there any restriction to SubmitOrderUnmanaged for NT8 addon?

thanks

Hello laketrader,

Addon's can't use the strategy frameworks, you would have to use the account directly to place orders from an addon. I would suggest looking at the addon sample here: https://developer.ninjatrader.com/do...pment_overview

Hello,

Addon cannot use the strategy framework. How about indicator framework? Can an Addon call or use the indicators provided from ninjascript editor?

thanks

Hello laketrader,

Addons can only use the addon framework. There is not a way to use indicators from an addon because addons are not linked to a Series like indicators or strategies in a chart. Addons are mainly for creating custom tools with custom user interfaces.

Hi,

I started to write my very first addon based on the sample that Jesse pointed out. I just would like to test how the order submission works. So the addon is just submmting a marker order every x seconds.

The addon compiled and ran without any error. The timer was working but I cannot see the orders in "Order" tab of control center. The code was attched. Where did I do wrong?

thanks

Hello laketrader,

That may be due to the timer, if you move your order placement code to just inside the button handler so when the button is clicked do you see it working?

Hi Jesse,

I moved the code insider the button hanlder. But got the following error. (see the attachment)

thanks

You would have to check which part of the code is causing that. That error means an object you tried to use was null.
