I believe Simba mentioned that he does not use a stop loss.

My dad demo traded for 2 months aggressively without a stop loss. He did quite well, winning more than 70 percent of the trades. He told me that stop losses simply lead to losing.

Then he opened a $500 mini account. On the second day of trading his real account, the market suddenly went 200 pips against him and wiped out his account. Luckily it was only $500 and not his retirement fund.
