In the documentation you reference below, you make a distinction between OCO and Bracket orders. Namely, server-side OCO is supported, and server-side bracket is not.

{screenshot attached}

What exactly is the difference, by your definition?

This is explained in detail, in this section and the following three sections:
Attached Orders: General Management of Attached Orders

You need to read through them in that order.


We also want to point this out in our documentation for our Teton Order Routing Service:

Trouble-free and properly managed server-side bracket orders. This is a huge advantage as compared to many of the other supported Trading services. With many of the other supported Trading services, either server-side bracket orders are not supported or there are various issues with using them.

Properly managed server-side bracket orders are so important since it makes the order handling very safe and low latency. With some of the other supported Trading services, the bracket order management is on the client side with a much higher delay from when the parent order fills, to when the Target and Stop orders are transmitted. This can be for example 300 ms and higher, rather than below 1 millisecond when managed on the server as they are with this service.

Server managed bracket orders, also mean that when the market is moving fast, there is a greatly reduced possibility that the stop order will be rejected. If the Stop order were rejected, it would leave the position unprotected.

Server-side Bracket orders are always enabled with this service regardless of the Use Server Side Bracket Orders setting.
Another advantage of server-side managed OCO and Bracket orders is that if your installation of Sierra Chart loses Internet connectivity or is closed, these orders continue to be managed on the server regardless of this and will protect the Position that they are intended for.
If you are using CQG, OCO and Bracket orders are not managed properly with that service. And Bracket orders are not server-side. This is all substandard. CQG users need to move to the Teton Order Routing service for properly managed OCO and Bracket orders.


Look at these posts from us in our Sierra Chart does not recommend CQG thread:

Search for the word "Bracket" in each of these posts, and you can see our comments, regarding this issue. This is why we also strongly recommend users to get off of Transact. We have terminated support for Transact. Transact is fully unsafe in regards to attached orders because there is not bracket order support or OCO support on the server side. Transact is 100% monumentally unsafe, with OCO and bracket orders because these are not managed at all on the server side.

The same situation also exists with Rithmic and Rithmic has developed integration to Sierra Chart using the DTC protocol but yet bracket orders are not supported last time we looked. If you are using CQG or Rithmic move to Teton. It makes no sense to use any other service, if you are trading CME Group.
