I miss TD Ameritrade. I was a "preferred customer" at TD Ameritrade, but at Schwab I am just a normal customer.
I do sometimes use ThinkOrSwim, but many times find it overwhelming on my cell phone, so many times use just the regular Schwab App. I tried trading on Robinhood, but hated it. The Schwab App has option chains, which is the basic thing you need. Honestly, I am still trying to learn ThinkOrSwim on the cell phone. I never thought I would be trading options on a cell phone, and it is an adjustment.
I have been doing the simplest puts and calls, mostly puts, and making good money. The secret is to always realize you could lose it all at any time, and put some of the money away.
That being said, back in the day I did various spreads, and even a few long iron condors.
A few years back, I thought I would quit options trading for good, but then trump came along, and I am back.
