But for IB, it seems like the margin requirement is crazy just for one contract? I dont know this platform very well, but it seems the margin required for this is 45,000? and the maintenance is even more. am i right here?
your screenshot shows vix from CFE exchange , somewhere in US. vstoxx is available from Eurex exchange , somewhere in Europe. margin requirement is rather low (around 500 eur ) I wouldn't touch vstoxx ; volume is very low
