I finally heard from Ninja. They suggested doing the OLDname, NEWname thing with the spf file. Did that. Didn't work.
Deleted the latest version and installed earlier version of NT8 We'll see how it goes.
Something very wrong with the platform.
Can you help answer these questions from other members on futures io?
I switched to Rithmic SIM data today and used the Rithmic DOM to compare. Almost zero slippage. Compared to 10-12 pts at NT. So the issue is somewhere in the NT system. No idea what but nothing else I can do as I have been asking them for months.
