I want put 2 OSO order in one time,for example,8:00 am ，now mnq is 14500,
place first OSO:
buy stop 14510 , bracket1 Sell 14520 limit ,bracket2 Sell stop 14490,
place second OSO:
sell stop 14490 , bracket1 buy 14480 limit ,bracket2 buy stop 14500

I need cancel one order when other order is filled,

does it can use OCO with 2 OSO ? or I need sub the order filled event ,cancel orther order?
how can I sub the order filled event?

You could watch for a few things. You’ll need to use a realtime data websocket. Once you’ve established a real-time data synchronization, these events will come through the socket like this:

[
  {
    e: 'props',
    d: {
      eventType: 'Created' | 'Updated',
      entityType: string, //there are a lot of options. I'll include a link for more info
      entity: Object //one of our Tradovate Entities. entityType determines its shape.
    }
  },
  //maybe more than one prop per response, make sure to process each item
]

You start the subscription to these events by calling the user/syncrequest endpoint on the WebSocket you want to listen to these events through.

One entity that you could look for is your Position (entityType === 'position'). When you have an open position, the position related to the contract that you’re trading will have a netPos !== 0 (could be positive or negative). When that position becomes 0 again, it’s been flattened. You can watch to see if your netPos has flattened and then send the next order.

ExecutionReports (entityType === 'executionReport') are useful for finding out what actions (Commands) you took that made it to execution. If an ExecutionReport has to do with an order, it will have execType === 'OrderStatus'. Then it will also have another field, ordStatus. This will tell you what happened to the order, including if it was filled (ordStatus === 'Filled')

You can look at a good list of the possible entity types in the docs for SyncRequest. Expand the Sync Response object below the definition for a good reference on what types of entities there can be.

Did you ever figure this out? This is my current issue, is having pending orders cleared properly, without having to liqudate
