One can go high level basic or start a deep dive low level journey which will take approx 2 years of daily immersion in the subject.
One very important note, these folks are primarly focused on SELLING (short) options which in some ways is analogous to being a Market Maker to all those on RV, speakers and subscribers that appear to only focus, or only interested in Long Options Strategies i.e. in effect Tasty will advocate their is opportunity in taking the other side of all Long Options trading Strategies
I remain of the view, often stated on RV since it's day 1 inception it's RV Options Content is entirely un-balanced and to date has never made any attempt to talk about the other side with short premium Option Strategies. I'm inclined to think this maybe due to their own and their invited speakers Compliance issues or quick win Sales interests i.e. who will be willing stick around if told up front getting serious about "learning short premium options trading" is going to take maybe 2 years to attain an average level of competence.
TastyTrade advocate Portfolios with -'ve Delta (always directional short), Positive Theta, -'ve Vega (short vol) made up of only the most liquid Options and Futures, they are agnostic, almost to the point of indifference on choice of underlying as long as they're are liquid. In approx terms, on any one trading day (US Markets) there are only approx 200 symbols with optimal Option Liquidity characteristics.
Note with Options it always helps the learning process if one has a good mathmatical background or at the very least sufficient mathmatical knowledge to appreciate and untilmately trust the maths involved. You certanly don't need a Math PhD.
