Quote from iukka:
Not my mother language, so forgive errors. There have been many possible stop-loss alternatives in this thread but one is missing: using ridiculously far-away beeing stop losses, something like 30 -50 % for a trade. This may sound a bit odd, but these kind of stop-losses works well in pull-back type swing-trading of stocks if you have enough nerves and can get 7 -8 trades succesful from ten. The trick is to use options and /or right position sizes to cushion inevitable wrong beeings.
This is a strategy for traders who have no ability to distinguish strong setups from weak setups, and can't figure out the price at which a trade's chance of short term profitability becomes invalidated. Your expected reward on a trade ideally should be greater than your acceptable risk.
A case in which your strategy would make sense is options trades where you're shooting for a 100% or better return and willing to risk 30-50% to let it play out.
