Resting OCOs

[spottysallrite]

When using a script, where do "One Cancels the Other" orders rest? On my computer? At the brokerage? At the exchange? Someplace else ?

Hello spottysallrite,


Thank you for your post.


The answer depends on who your broker is for the orders. We have a list of where your orders reside, including notes about OCO orders, in our help guide here:

If you are curious about different order states, we have definitions listed here:

Additionally, it is important to understand the risks of electronic trading and using OCO orders, as described here:

I hope these resources have been useful in answering your question. If you have any additional questions, please feel free to ask them here.

Ok, I use Continuum and the ES instrument. Will those orders still execute even if my internet connection fails?

Hello spottysallrite,

Thank you for your reply.


For Continuum, most OCO orders are supported natively on their servers and would execute properly if your connection fails. There is a disclaimer at the bottom of the page in the connection guide that provides more information:

https://ninjatrader.com/ConnectionGuides/NinjaTrader-Continuum-Connection-Guide

"Disclaimer

1. When cancelling orders, working orders within an OCO group will only be cancelled if any order of the group is cancelled directly within NinjaTrader. In all other scenarios these working orders will remain working.
2. An OCO group that has an order rejected will not cancel any remaining working orders in the group. Any pending orders will not be submitted and instead rejected.
3. There will be an approximate 200ms delay between submission of OCO linked orders."

You could also reach out to your broker directly for additional clarity and assistance if needed.

Thank you for using NinjaTrader.
