Most difficult thing is understanding why a trend following system that never loses money in any year over its last 20, averaged 100% compounded, and largest drawdown was 3 months and below 40% and always rebounded to more than regain losses within 6 months. Why did my trader immediately enter a 4 month drawdown followed by complete destruction of over -95% wiping out my account. So how to prevent stupid losses when traders know system has stopped working? Why should I trust anyone?
No trend following strategy has made money every year over the last 20. None makes 100% compounded. So why did someone blow your account out? Who knows, but it wasn’t trend following. Sounds like options selling. That makes money all the time then one moment you are dead.
