Hi Tom : It will be fantastic if you can arrange a session with one of the larger market makers (citadel for instance is the largest).
Questions to be addressed with them:
1. Is there still a weekend decay effect in 2022, or is this an old myth ?
2. How do they address pricing of complex option trades-- for instance a butterfly/iron order with 4 arms. How does the bid, ask and mark price differ in terms of the trade likely going through during high volatility and low volatility
3. How do they address pricing of less complex option trades-- spreads with 2 arms. Is it better to get a complex order (4 arms) filled as a single order or break it upto into 2 spreads from a pricing basis ?
4. Movement of implied volatility of all large options in relation to the VIX-- the spx/spy implied volatility, is obviously representative of the VIX and moves together. How about the other larger Indexes-- RUT and NDX ?
5. How much is the movement in price of the options relatively within a day, if the market prices not moving, meaning is the theta decay mostly overnight, or how much does it decay in the daytime? how does their supercomputers address this ?
6. Which are the best brokers in terms of speed of order execution from their perspective ?
