These commenters have no clue what they are talking about. You don’t need to worry about hostile behaviors in the way they claim. These HN individuals are not domain educated and are spouting highly uninformed nonsense. Silly ideas like market orders take liquidity and limit orders provide it show an extremely rudimentary familiarity with only basic terminology of the field and with no understanding of the extremely dynamic and complex nature of modern capital markets. For instance they don’t realize that most longer term managers execute as much as 80% of their orders as passive limit orders, yet they are the ones that are actually liquidity demanders not suppliers.
