RE:OpenAI reply on 001 How convenient. I believe originally it was created to hide insider trades, then the retailers complained about the the ruse, the unfairness.
Then they changed the game to add "everyone" can trade through 01, wow now I'm (the retailer) as important as an insider!
The ruse is still to hide the insiders (can include money managers, financiers) and give them absolute advantage.
Just think, they provide the broker identification ONE MONTH LATER. What good does that give you, would you analyse what happened one month later in a micro second world?
