ATI vs OIF

[Atomic]

I run in sim while my broker is running live.
In my log files an order placed looks like this:
OIF, 'PLACE;Sim102;ES 03-23;Buy;1;Limit;3898.25;0;Day;;System1|53779|ES 03-23|Mar 10 08:06|Sim102|Buy|Lim|1|3898.2500;;' processing
An order placed by the broker looks like this:
ATI, 'PLACE;AcctNo;MES 03-23;Buy;6;Limit;3898.25;0;Day;;System1|89360|MES 03-23|Mar 10 09:06|AcctNo|Buy|Lim|6|3898.2500;;' processing

This is the same order. What is the significance of ATI vs OIF?

Hello Atomic,

Thanks for your note.

In NinjaTrader there is an Automated Trading Interface (ATI) available and this allows you to submit Order Instruction File (OIF) orders.

More information about OIF could be found on this help guide page: https://ninjatrader.com/support/help..._files_oif.htm

Based on the information you shared, it seems that OIF from NinjaTrader and ATI from your broker refers to the same thing. You could reach out to your broker directly to confirm exactly what ATI refers to on their end.

Please let me know if I may assist further.
