#止损策略 Protect the Principal

Setting a stop-loss is a trader's preferred strategy for survival in the trading market. A stop-loss is a predetermined loss limit that uses trading discipline to manage human nature, preventing the temptation to turn short-term losses into long-term losses, or even liquidation. A stop-loss strategy makes the cost of each mistake manageable, thus allowing you to protect your principal while waiting for the next opportunity. Protecting the principal is the first issue to consider in trading, followed by profit.
