Ratio 1:2 & money management

Hi all ...
is there any strategy or trading system or any trading way with stop-lose to take-profit ratio 1:2 ? (or it just a rocky talk....)
I have Idea about MM but need ratio 1:2 .........
Please advice ...

Hi Waddah,

I've been hearing that a lot myself, about that 1:2 ratio, though I always wondered what people meant by that since it's usually difficult to know what to expect. However, I think that those who use that ratio could possibly take into account the resistance and support zones when trading allowing them to ride the bigger moves when the price finally breaks. But it's just a wild guess
