         | possibility of waving of margin requirements at the whim of 1
         | person at the FTC (making margin requirements essentially
         | meaningless for some participants), etc.

             | "having a conversation" (or whatever engagement metrics
             | you're optimizing for).

               | Or better yet I'm wrong and he can tell me why GME is

       | 
       | That's striking. Trades that are cancelled happen in bunches -
       | after a trade completes, there will be orders placed in the next
       | few milliseconds to re-probe the market, then relative quiet.
