Fidelity still just has Tuesday 5/10, no Tuesdays beyond that. I checked IB earlier, and they had the same.
I opened an order for a 5/9 5/10 calendar at the 4230 strike, not filled yet.
I was surprised regarding Tradier's account size requirements. I tried them for a few weeks, as I heard their platform was interesting. They
also have that strange confirmation process.
