We will agree to disagree. I get what you are saying and agree to some point. 6th digit is always MM 5th digit is not always an MM. I purchased the 500, 5 digits..not an MM trade.
Exactly. Happens sometimes esp with large orders when the bid/ask is changing and generous MMs fill your order favorably to the 5th or 6th deciminal place, but it would be that much harder to do for a small order like 911, 100 or 500 trade imo
