I am new to the forums and impressed by the amount of data on here. I am not new to options trading. I have been trading options on equities for 8 years now. However, I recently discovered S&P e-mini options on futures. I was researching high probably income scenarios with SPX when I came across options on futures. I could not find a thread on this in the forum related to this. If anyone can point me to the right thread I would appreciate it. 1.) I would like to study the risks of high probably 1.5 to 2 standard deviation vertical spread trading? 2.) What are the risks of trading a derivative on a derivative? 3.) Notational value differences between SPX, ES, and ES options? 3.) Any websites or links out there would be helpful. Thanks.
