Hi All, I enjoy this new thread to thank all the participants, I learned a lot and will continue this way thanks to your explanations. I have 2 questions I cannot figure out: The first one is related to the probability analysis of the TOS platform (see picture attached) What does that mean? How can we use it to put a trade in place? Second question is about butterfly. What are the strategy to get out if the trade doesn't go the way we want? E.g. is a good idea to STC the positions in order to have a downside bias? Or to BTC for an upside one? Thanks for your help, support & inputs Paul
