I strongly disagree with the notion that more "guardrails" are needed for retail investors dealing in so-called "complex products." While some products are truly complex and require an investment of time for an investor to fully understand their risks and rewards, other products you name--particularly options--are not truly complex or difficult to understand with a modicum of study. All investing carries risk, even time tested buy-and-hold forever.

More regs are not necessary except on margin. Leave the small retail trader alone. The market is fixed enough by all the large players. You might want to regulate so called stocks such as DWAC. That is where the criminals are. Leave the traders alone with your rules. Not needed.
