The people who are saying to read some books, trade small lot sizes and keep a trading journal are right on.
It is a bit of work to learn to trade options successfully.
Anyone in the options business who says that you don't need to know how a car works in order to drive one is scamming people. It's a lousy analogy. In this case, you absolutely do need to know how the car works.
At some point, probably soon after beginning, most people lose some money. The correct response, at that point, is to say to yourself, "Could I possibly have avoided this, and how?" If you do not possess a deep understanding of the subject, how can you possibly answer that question? If you cannot recognize and fix your (inevitable) mistakes, how are you going to learn trading? There are no short cuts.
Therefore, it makes no difference whether Optionetics courses, or anyone else's courses, are good or not. There is just no way that a few days of lecture and a spiral-bound notebook are going to prepare a person for trading options. It's more complicated than that. Everyone who wants to be successful at this will have to do the hard work. The only way around it, is through it.
I notice that there are some honest professionals out there--Wolfinger, McMillan, Sheridan--who are successful in this business and have written inexpensive books or made free videos. And not one of them is telling you that you don't need to know how a car works--au contraire.
