Does anyone use Fidelity for their option trading? I have been using them in the past and they recently offered me a new product iSpreads Pro. It seems to be a good analytical tool, which offers me Greeks, theoretical values and implied vols. All of the data is streaming and they allow me to graph my p and l. I can direct my own trades and see size for any exchange. No market data or platform fees. Contract price is $1.50, but the functionality seems legit. Curious if anyone else is using and what they think or if there is something people like more.
