First of all, it needs to be clear that losses are inevitable. On the premise that losses are inevitable, what we can do is to control the losses to the minimum, enlarge the profits to infinity, and the higher the comprehensive balanced profits, the better. Mainly through the following methods: 1, strictly set the stop loss; 2. Be sure to strictly calculate the profit-loss ratio before placing an order. If it is less than11,the ticket will never be issued; 3. When there is a floating profit after invoicing, keep moving the stop loss to minimize the loss. With the development of the market, keep moving the stop loss, enlarge the stop loss and let the profit run; 4. Reducing the number of transactions will improve the winning rate; 5. Whether it is long-term or short-term, we must conform to the general trend and go against the small trend, and we must not think about killing long and short; 6. Do a good job in fund management and strictly control positions, preferably fixed positions (it is best not to change positions frequently when the total amount is within a certain range, because no one is sure which stop loss will win).
