That is, taking the trend as the principle, according to the dynamic reflection of the disk, grasping the minimum ripple spread in the daily price fluctuation, and making short-term and active trading speculation. For example, if the trend is expected to rise, buy, and if the price rises, immediately close the position; Seeing that the price is not going down, continue to buy, and close the position if you make a small profit; In case of short-term price correction, that is, stay put until the price is no longer adjusted and continue to buy until there is no immediate trend to follow. In the case of decline, the situation is just the opposite.

2. The dish feeling fried single method:

Mainly based on trend speculation, supplemented by counter-trend speculation, mainly according to the dynamic reflection of the disk, grasp the minimum price difference in daily price fluctuations, and carry out active trading and passive speculation to grab the callback or rebound. If you take the opportunity to buy in the rising price trend, the profit will be flat; If you see a price correction, don't wait for the opportunity, seize the opportunity to sell quickly and close the position quickly until there is no trend to follow. But the principle is still based on the trend. The decline is the opposite.

3. Arbitrage speculation method:

This is a rare speculation method, and it must be the same variety in the same market when speculating. In the rising market, choose the strong month contract to buy and the weak month contract to sell, so as to achieve the purpose of profit. Shorting is the opposite.

4. Countertrend speculation:

This kind of guess is very strange, usually difficult to accept, and it is also a rare guess. That is to say, in the upward trend, the speculative method of grabbing price retracement in stages every day; Decline and vice versa. I've never seen such a guess with my own eyes. It's difficult.
