NFA fee is doubling from 0.01 to 0.02 per side starting January 1, 2018. https://www.nfa.futures.org/\/news/newsNotice.asp?ArticleID=4950
I wish they would charge even more and make it .03. The NFA is such a valuable self-regulatory organisation. They protected everyone so well against MF Global and PFG and...opps! I can't imagine life without them!
Yes - they are the picture book example of being a self regulating organization. They would never allow the selling of high speed data feeds on the exchange linked to predatory HFTs. The will persecute to the full extent of the law spoofers from the outside that have not paid for this privilege.
