OIFs must be written to the folder "My Documents\<NinjaTrader Folder>\incoming" and be named oif*.txt. You can simply send an oif.txt file however, it is suggested that you increment each OIF so that you end up with unique file names such as oif1.txt, oif2.txt, oif3.txt. The reason is that if you send a lot of OIFs in rapid succession, you do run the risk of file locking problems if you always use the same file name. This will result in a situation where your file is not processed.
Each file must also contain correctly formatted line(s) of parameters. You may stack the instruction lines so that each file contains as many instruction lines as you desire. The delimiter required is the semicolon. Although this section is a good reference for generating correctly formatted OIF, it is highly suggested that you use the Automated Trading OIF Builder to generate OIF strings for comparison to your OIF generation. Files are processed the instant they are written to the hard disk without delay.
