Quote from tomahawk:
Not every YM trade setup will have the potential to earn you +27, and not every day is it worth waiting around for only the +27 setups. Also while most trades should have a 1:2 risk:reward, some should perhaps risk a little more, some a little less, depending on different criteria such as time of day, the particular strategy/setup, your current mental state, where your PnL is for the day/week ....
