It was NWBO's data so NWBO's decision when to publicly release.
NWBO could have disclosed summary TLD and still presented the full presentation at NYAS. Every organization like this understands that public companies have compliance issues they must abide by.,
It is also the case that the national exchanges enforce news trading halts by request of the company. But NWBO does not want to abide by governance rules that would be required for a national listing, so they are OTC.
The fact that NWBO does not want to abide by the rules respected companies abide by is also the reason Denmark Banks and Merryl Lynch do not allow customers to trade it. They do not want to the hastle of dealing with crap stocks.
That's not the version I read when I saw it posted. I don't have the post, but I recall it was well in advance, but FINRA was not cooperative.
Excuse me for being cynical, when silver was being run up by activist traders, let's call them, halts were placed multiple times, and lifted for selling not buying. Same with the meme stock circus. Plus, there's so much public data and information, save for next level high intelligence, that show documented criminality rise to levels that normies, who have yet to be exposed, and in most cases are unprepared to handle.
