@volatilitypays,
Do Not Try to install via Nt8
1. Close NT8
2. Determine if you have OneDrive installed in Windows
3. Open the compressed folder, copy the dll file
4. Paste the dll file to Ste5 or Step 6
5. With OneDrive:
"C:\Users\?????\OneDrive\Documents\Ninjatrader 8\bin\custom\"
6. Without OneDrive:
"C:\Users\?????\Documents\Ninjatrader 8\bin\custom\"
7.Start NT8, there should not be any errors related to OFL in the log
8. Look under Indicators tab, OFL should be listed
If this does not work for you, then the file you have is corrupted or not compatible.
Maybe others in this forum can help. Good Luck !
