Quote from intradaybill:
If you trade with a win rate less than 50+% your risk of ruin is guaranteed no matter what your R:R is. You can only delay the inevitable if you risk a small percentage of your account. All trend followers with a win rate of less than 50% are doomed. It only takes a few months of choppy market action to cause a drawdown of 50% or more if fully invested. If invested with leverage, ruin is inevitable and fast.
Learn the facts before you end up ruined...This is simple algebra for high school students...
Please stop peddling misinformation and distorting facts to fit your opinion.
While what you are saying is true in a scenario like a simple coin toss game, trading systems have other variables along with win rate that need to be considered to calculate risk of ruin. I can refer you to the proper material for reference if you will take the time to put down your 7th grade algebra book. It's written by a statistician with a PhD (who is NOT a trader) and includes tables that you can insert your win rate and easily calculate your risk of ruin in case you're not able to do the math on your own.
I've been trading a system with well below a 50% win rate (41% to be exact) for more than a decade and make my living doing so. My "win rate" on a monthly basis varies from 12% to 75%, and I've made money in months where my "win rate" is LESS THAN 25%... plus I've NEVER HAD A LOSING YEAR. How did you do in 2008? My account nearly tripled in value.
Until you are willing to admit you're wrong about your risk of ruin calculation for trading systems, it is you who are DOOMED to fail because you put your faith in incorrect information.
