the spread widens because limits are cancelled. duhPointless really. I buy call and put options and numerous times, the market maker widens the spread between bid and ask say, it is now bid 2.00 ask 2.50. Market maker drops the bid to 1.00 ask 2.50. That is why as a retail trader, you should always use limit orders even if hitting the bid or ask prices. That way, you do not overpay. I just cancel my order when I see that. The next morning, chances are good, the same market maker now offers the option at bid 3.00 and ask 4.00. The key is waiting for it the next day. Market makers will raise the option prices as they are selling the cheap options they got from amateur retail traders, giving you a better fill assuming you are trying to get out! Do not be fooled and taken advantage of!

manual traders will get shutdown by the fcm because the fcm will be finedMy understanding is not a ratio. I spoke to member services at the CME 2 years ago for an automated client. No manual trader can hit 20,000 message units per day. Even an automated client that needs to enter that many orders just needs to register as a MM. It is about 15 orders per second. What they want to avoid is spoofing and those that do not add to depth and liquidity from using bandwidth.
Anyone concerned with this should contact the CME.
