• Question from Privateer - Permission to speak freely sirs! Hi guys, Love the show and the entertaining military themed education. I've recently been learning about an exciting strategy called writing call options with CFDs. The claim by the teacher is that CFDs can leverage the return on premium selling by ten times, and reduce your break even significantly. I'm very invested in how this could apply in selling both legs i.e. covered strangles or straddles. Can you discuss the downsides, upsides and hedging strategies used in this scenario,and how to mitigate risk especially on the put leg. Sirs yes sir!
• Question from Axel D. - Why does open interest only update once a day?
