How long does it take for funds to settle for trading daily?

I'm still not too sure how good faith violations work. i already have two because I'm not exactly sure what the policy is. I've been waiting two business days to sell for this reason, but lately I've been trading short-term leveraged ETFs and would like to buy and sell once a day.

So if i did something like this, would it be a violation?

1. Buy at pre-market
2. sell at after-market
3. Buy again at pre-market the next day the same ETF
4. Sell at after-market
5. Repeat every day

Does that satisfy the D-1 fund settling time without a good faith violation?
