When the stock market or futures market is in a weak position, in order to ensure the safety of funds, stop-loss points should be set when opening positions. Once the stop loss point is reached and it is determined that the trend is weakening, it is necessary to decisively lighten the position. Usually, the stop loss point is set at the 10 moving average, important support level or sensitive price of the stock, or it can be 10% of the opening cost or the acceptable total loss amount.

Lightening positions is skillful, generally losing half of the positions for the first time. After cutting off half of the positions, you need to play it by ear. If the stock price or futures price rises, you can use the other half of your position to reduce losses or even turn losses into wins; If the stock price falls further, you can make up for it with the cash in hand, dilute the cost step by step, and seek opportunities to solve the problem.
