Dear fellow traders, I got into an SPX AM options trade. Compared to the SPX 0dte dailys, are the executions typically poorer? I expected to at least get between the bid and ask especially with an ~7.0 point wide spread as can be seen in screen shots, but got filled at worst price. IB is broker. Fills with SPX 0dte are typically between the bid ask, especially for NDX 0dte. Comments.
Why oh why do you use market order? Just use limit order and take the offered Bid/Ask. This will in 99.999% of the cases be filled immediately. But you can even do better by using the MidPrice, though this is slower.
limit order used, as always. does anyone know if SPX AM give a poorer execution compared to SPX 0DTE ? if not what could explain this worst fill?
