Trading according to trend line indicators. Take the rise as an example. The retracement point of the trend line is the buying point. If it falls below the trend line by 8 points or 5 points, stop loss. Downward trend, rebound to the trend line to short, when it breaks through the trend line and rises instead, the stop loss is 8 points or 5 points above the trend line.

On the bottom or top signal day, when a futures variety goes through a wave of ups and downs, a big Yang or a big Yin line appears one day, indicating that the top or bottom of a certain level may be established.

Form a double-bottom or triple-bottom buying, especially reminding you that when you buy when a futures price reaches the third bottom, the risk you take should never exceed 10, because the third bottom falls below, especially if the bottom is near the prices of the first two bottoms and touches your stop loss order at the same time, indicating that the trend has changed, you should immediately sell long positions and short stocks.

For double top or triple top selling, this method is the same as the second judgment rule.

After a triple top, the top has been down or down, and the high point in the rebound is decreasing, which indicates that the futures price is weak and is about to go down.

Breakthrough point, when the market is in a high and strong region and the bottom price is finally broken, is the signal of the main trend reversal.
