Swinging for the Fences
Most traders begin their trading careers, whether consciously or subconsciously, by visualizing “The Big One” - the one trade that will make them millions and allow them to retire young and live carefree for the rest of their lives. In FX, this fantasy is further reinforced by the folklore of the markets. Who can forget the time that George Soros “broke the Bank of England” by shorting the pound and walked away with a cool $1 billion profit in a single day! But the cold hard truth of the markets is that instead of winning “The Big One”, most traders fall victim to a single catastrophic loss that knocks them out of the game forever.
Why the 2% Rule?
The best way to avoid such a fate is to never suffer a large loss. That is why the 2% rule is so important in trading. Losing only 2% per trade means that you would have to sustain 10 consecutive losing trades in a row to lose 20% of your account. Even if you sustained 20 consecutive losses - and you would have to trade extraordinarily badly to hit such a long losing streak - the total drawdown would still leave you with 60% of your capital intact. While that is certainly not a pleasant position to find yourself in, it means that you need to earn 80% to get back to breakeven - a tough goal but far better than the 400% target for the trader who lost 75% of his capital.
