I am looking for speakers for an options trading meetup in London. Topics we like: advanced option strategies, position sizing and risk mitigation on the various constructs we use to trade, zero cost trades, synthetics in various configurations, strategy scanning tools and techniques, limited broker and platform demos (it's not a sales event to be sure). PM me if interested. Can you sponsor an event? We'll be 20-30 people for our first event by the look of things. We need space, drinks and food.
