I mostly used to trade spreads, DTE 45, delta 20-30 (closer to mid) for the short put or short call on tech stocks and a few non-tech stocks. With that many days and low delta the bid-ask is very wide for a single leg which compounds when entering it as a spread.
TOS were still part of TD the last time I used them for options and they were exceptional with fills. As I didn't have time to trade options for the last 3 years while I was selling my businesses I took advantage of a massive uncapped 4% transfer offer from Webull. But I have been using Fidelity as my brokerage for new money (primarily came from the sale of those businesses) which I could transfer to Schwab. Fidelity's desktop app is not good for 2 leg trades.
Thanks.
