I bought 1 March contract for $20.5. Let's say VIX closes at the relevant time on the expiration date at $25. I will get paid $25,000 into my account (based on the VIX future 1,000 multiplier) at that time. So my profit from the purchase (ignoring commission costs) would be $4,500. Conversely, if VIX is at $15 at the expiration, I will get $15,000 swept into my account, and my loss would be $5,500. Does that sound right? Thanks!
