I use fidelity and feel i get really good fills usually always just as good as official alerts or better, although there may be some luck involved when getting better fills, down to timing really. Im trading with 20k account, although i would like to know how it would be with a 100k account, as I’m getting more comfortable with options i do want to go bigger. If anyone else trades a larger account size with fidelity i would like to know.
i was also able to negotiate down to a commission of 0.50$ per contract after a few months of trading with them.
also i love the interface and tools available with fidelity. The app is ok too. Always able to do four legs trades which i have seen some aren’t with other brokerages. I have considered tradier for the 10$ per month deal which would save a ton although I have a hard time leaving fidelity as it’s what I’ve been become accustomed to.
