How much does etrade charge a monthly fee?

I'm curious to know, could you please clarify the monthly fee structure for using eTrade's services? I'm specifically interested in understanding if there's a flat monthly fee that I need to be aware of, or if their charges are structured differently, perhaps based on account activity or other factors. As someone who's considering eTrade for my trading needs, it's important for me to have a clear understanding of all associated costs before making a decision. Thank you for your assistance in this matter.
