No. Obviously there has to be some sort of stop loss in place. No system can avoid a 1987 or 9/11 type event, but every system should have an exit plan for WHEN those events occur.
But, then again, this is an aggressive system, so if you are not putting too large portion of your assets into it, then you could just let it fly.
It always gets back to what your own personal goal is.
One of my backtests was setting a 5% stop loss and taking profit at 15% the next day irregardless....this was back in the initial ema(nasi-7) testing, and that did improve the resluts. Also, the system gave a big drawdown in 2003. I would have bailed long before it got so bad.
