Which account sends an order first?

[takeaseat]

Let's say I have 10 accounts each running the same strategy. In what order, or how does ninjatrader determine which account sends an order first? I understand we're talking milliseconds or lower, but just wondering.

Wondering in a single core environment, as well as, a multicore environment.

Hello takeaseat,

NinjaScript instances will be asynchronous and there would be no guaranteed order. It's a race to see which strategy receives data first and runs OBU and calls the order method. For strategies running on the same instrument it will likely be in the order the strategies were added to the chart, but there is no guarantee on which script will update first.
