We have talked in the past about having larger stop-loss threshholds than the actual expected reward, and the backlash on forums when this type of trade is even mentioned. The logic of the backlashers is that you have to have reward larger than your potential loss to win in the game of trading.
I wanted to explore the concept a little bit further and just think through the implications of what it means to put on a trade where your potential reward is smaller than your potential risk.
Let’s start with an example… If a stop is 2x the size of reward (e.g., a stop loss would be triggered at a loss of 10% but we’ve set a price target of 5%) then we have to get at least 70% of our trades correct to make money. (66.7% plus slippage and commissions, I’m guessing ~70% if not higher.) To me, this seems like a fairly high hurdle to start with, though it is certainly possible. (more…)
