First, read this info on MM. I posted it before.
MML
Now, you have to understand that all indicators are reflectors of price, not effectors. Price couldn't care less that a 1-8 MM line exists at any point. The MM lines are there for your information only. Once price violates the levels, of course new lines will be calculated based on actual price action. What used to be a support level may become a resistance level when violated. A weak are may become a strong area, etc.
Don't get wrapped up with any of the static level indicators. They are for planning purposes only so use them that way.
