What is an option strategy that someone could employ to simply go long/short volatility?? Assuming I want 0 delta(0 gamma if possible) risk in my option position, how do I take a directional view on volatility? I know that Strangles/Straddles/Iron Condors are all ways to play volatility expansion if it goes beyond the width of your strikes. Not to mention you do maintain a 0 delta position until the price starts trending one way or the other for Strangle/Iron Condors. Are these option positions only way to play pure implied vol?
