Quote from ogarbitrage:
Are you seeing these 'anomalies' in settlement prices only or in the live bid/ask?
Settlements are a joke and 99.9% do not represent where the real market is.
I have indeed seen cases where the settlement prices of out of the money options on certain stocks or futures were much lower than the prices at which they actually traded every day.
Maybe anomalies is too strong a word in my part.
I guess what one really needs is tradeable or exploitable intraday variations from model pricing that do nevertheless revert so that one can exit the trade with a profit.
I believe I am seeing these and will look to post some real examples for comment if I can firm them up.
But probably you deal in these all the time already.....
