Not sure what you mean, but you do a stop loss to make sure you don't lose your shirt when a stock moves against you.
No one intends to sell at a loss but that is part of the game. The problem is when market manipulators artificially cause the price to move against you thus triggering your stop loss.
If you don't want to sell your stock at a price below $X (for any value of $X), you should not tell your broker to sell below $X.
If you want a mechanism to retain upside while limiting downside, it exists. It's a call option, not a stop loss order. If you don't understand the difference you should not trade.
If you could explain the specific mechanics of what you believe is "market manipulation", it would be very helpful.
