OIF error: An entry with the same key already exists.

[Lumbeeindian17]

Can someone tell me what this crash means?

I'm trying to use the ATI interface.

Hello Lumbeeindian17,

Welcome to the NinjaTrader forums!

May I confirm that each new .txt file has an enumerated file name like OIF1.txt, OIF2.txt, as directed in the help guide?

May I confirm each new order has a unique OrderID?

Yes the file names are increments. For the device question I am not adding an order ID. Maybe this is my issue. I thought it was optional.

Hello Lumbeeindian17,

No orderid is ok.

May I have you send an email to platformsupport [at] ninjatrader [dot] com so I may request further information?

Please include a link to this forum thread in the email.

I added the order id with the command below the first two trades went through fine but on the 3rd run it crashed with the same error. Maybe an issue with using powershell?

"PLACE;;ES 12-22;BUY;2;MARKET;;;DAY;;$(get-date -f yyyyMMddHHmmss);;" | Out-File -FilePath C:\Users\OMIT\Documents"NinjaTrader 8"\incoming\oif$(get-date -f yyyy-MM-dd-HHmmss).txt

I sent the email you requested.

Correction, it only worked once. It failed on the second run not the 3rd.
