Stop loss and take profit is not only a liquidation mechanism, but also an effective measure to control risks and ensure profits.

Take profit is to "profit" from a point on the basis of current price, and stop loss from a point on the basis of current price;

However, the actual profit and loss is calculated according to the opening price and the flat warehouse price, so taking profit does not necessarily make money, and stopping loss does not necessarily lose money.

For example, 1274 is long, stop loss 1267.5, current price 1289, stop loss is raised to 1283, and then the price is adjusted back to sweep the loss, but the whole transaction is still profitable.

For example, 1290 is short, stop loss 1300, current price 1297, take profit 1293, the price drops, take profit 1293, but the whole transaction is still a loss.
