Actually MM is the most talked about thing on every site but this 1 thankfully, it's always the easiest to understand and do, which is why it's the most talked about.
Picking Entries with the trend, with a better profit than loss potential is where the money is made, is the important part.
1 Poster on another site, Zero Trading Edge believed that strongly in MM risked 1% per trade, TP set at 1% and believed that eventually she'd get a lucky run, but even with perfect MM you still lose and Luck isn't even real.
