NT Support

I am having a bridge created between MetaTrader 5 and NinjaTrader 8 using ATI file interface. Its giving me an error, Unhandled exception: An entry with the same key already exists.

My developer is assisting in getting this working. Can you please help me out with what might be causing this?


Thanks
Jeff

Hello Jeff,

Thanks for your post.

Could you please confirm that each new .txt file has an enumerated file name like OIF1.txt, OIF2.txt, as directed in the help guide page linked below.

Can you also confirm that each new order has a unique OrderID?

Ok. I did resolve this. However, I'm not sure if its a limitation with using OIF files but it seems there is a noticeable delay when uploading a new OIF file to the incoming folder and NT8 processing it and executing the trade.

Hello Jdmtrader,

Thanks for your note.

OIF files are processed the instant they are written to the hard disk without delay. This information could be seen on the help guide page linked below.

See this demonstration video showing the above: https://brandonh-ninjatrader.tinytak...OF8yMDg4MDY1Ng

Please open one chart window for the instrument you are submitting an OIF order to and have all other windows and workspaces closed. Add the OIF .txt file to the Documents\NinjaTrader 8\incoming folder to submit the order.

Do you see the order processed without delay as seen in the demonstration video above?

Please let me know if I may assist further.

Turns out, I had OneDrive enabled and that was causing latency, I removed OneDrive syncing from the My Documents folder and that has resolved the issue.
