Thanks, Owen. Yeah, this really is the story of the volatility toolkit. We're seeing investors gravitate towards that toolkit to be able to manage risk, both the upside as well as the downside. VIX options, particularly we've been talking about this for a little while, is that the lower VIX, the historically low VIX in general that we've seen for most parts of this year, when we see that volatility spike, such as we did yesterday, it's going over $19, or in during April we saw it pop to $19 around those volatility events that occurred, we see customers then monetizing or rolling those VIX call options or those VIX call spreads they got on place. And then we see the resetting and rolling of those as we go through time, looking to prepare for those tail risks that may well occur, particularly when you think about the macro environment. We've got geopolitical risks, we've got elections, which are historically a really big catalyst of volatility, and those daily economic data, whether it be CPIs, central bank rate decisions, or earnings calls. So, when we think about VIX options and VIX futures, when you see a spike in VIX, we see really large VIX futures days. Yesterday, we saw over 400,000 VIX futures contracts trade, the volatility popped over to $19.5 yesterday. SBX options always continue to play their part, whether it's at the shorter end of the curve, or managing that longer-term exposure in and through and beyond the elections there. So, the utility of each product, using conjunction as well as in isolation, is really what we see developing over time. And then, our job is to continue to innovate products around that. And so, when you think about the differences between implied and realized volatility, variance step forward, variance futures, on-exchange, transparent, capitally efficient for a trading strategy, which has recently become very hard to achieve OTC because of the unclear margin rules. So, bringing that on exchange, an exciting development there, along with those VIX options on futures, all before the US election. So, really interesting setup for the rest of the year.
