4 to 1 on the ES and yes, they do fine. But your broker may have clients with low ratios so it balances out. I had a friend who was fined last year. I have never personally been fined, but I do watch my ratios. Products have different ratios. ES is the lowest at 4:1 The CL is 25:1, grains around 50:1 , interest rates 10:1.

Help me out guys. That is a broker thing or CME thing? And 4:1 what?

CME thing. They adjust quarterly I believe.

No I was referencing your earlier comment on messaging limits and the ratios mentioned. I'm coding things that quote and cancel/replace often (often for me at least) and it sounds like you are talking about a hard limit on CME messaging. What is the ratio in reference to?

Thanks in advance for your time.

Every Class A firm that deals with CME clearing has to stay within a certain ratio. The ratio is the messages (orders, modifies, cancels) to the volume of the trades. The CME sends a notice to your firm the day after a violation and they identify the sub account with the FIX SenderSubID field. I think they use other ways to identify your account.

Then somebody gets sent an email to pay the fine. Not really sure about that part.

I never knew that. Thank you. Did a CME Google and found some more information:

Did you see a pattern you can exploit? How can your system spot that pattern in real-time? How can your system execute to exploit that pattern in real-time? I haven't looked at the original data and Mike's post is third hand, but this is stuff for signal analysis and pattern recognition. Look at the x-axis of those charts. It's milli or micro seconds. Interesting, though. And no, X_Trader won't do that for you. RTD Tango could if you were really good with C++. Move along, move along.

No, stay with me, i think we are really on to something here.
