I posted earlier on the subject of covered calls and would like to add that overall I love this app.
The ability to trade options on the penny, and the way it is organized are great. But the lack of advanced strategies and the fact that moo moo charges a fee for options trades is a huge. negative.
Moomoo Lily : Hi, we are currently building our option strategy capacity and are offering Covered Call strategy to our users. We will gradually support other commonly used option strategies, including vertical spreads, straddles, butterflies, etc.
