There is a fundamental question that we have and we don't have an official answer. The question is if currencies should be base2 MM or base10 MM. I found that GBPUSD can work from base2 or base10, but my research indicates EURUSD works from base10 despite claims by Murrey in his book it should be base2 (although he didn't make that claim directly). In MM trading platform, Murrey inverted the USDJPY and then applied a base2 function. So the MM trading platform has JPYUSD with base2 lines. I didn't check the lines or math, but it is plausible.

A visual test over a year of data should show many many bounces off the 0/8 and 8/8 lines. The 1/8 and 7/8 seem statistically true, but the 64 rules of stocks don't apply to forex. The zones of conflict don't work in forex.

Don't forget that there are often half shifts in the MM lines, so 4/8 and either -4/8 or +4/8 are the new 0/8 and 8/8 lines temporarily.
