CFD trading - need a low spread broker for indices

Can I find a regulated broker with spreads less than 1 or 2 on popular indices.

CFDs are not allowed in the U.S.

 

They are allowed for professional traders in the US eg archegos $80 billion blowup was CFD/total return swaps.

 

Oanda has a 0.4 spread on S&P 500: https://www.oanda.com/rw-en/trading/spreads-margin/

 

If you trade "size", ig-markets

 

CFDs are banned for US Citizens and Residents (i.e. Greed Card Holders) in US, same as if you can't open a forex account in local banks. I put up 10% margin for WTI futures with IBKR while an old buddy put up 3% margin with a HK/Singapore oil broker.

 

Isn’t it more suitable for big time investors?

 

I thought of giving it a try but got to know that it offers low leverage. Is that true?

 

I don’t but I will keep it in mind in case I change my mind.
