But the opening time is often the best time for speculation. Before deciding whether to participate in call auction, let's make an evaluation of "selected experience events" and "inevitable experience events".
Because futures are closed bidding, and the opening price may be significantly higher or lower due to the overnight rise and fall of foreign futures markets, this price may greatly deviate from the reasonable market price. In the first article "The Law of Time", we discussed the most active opening trading, the biggest price fluctuation and the fastest price fluctuation. As a short-term small capital transaction, opening is the best time to intervene.
But the problem is that it is difficult to judge the price trend in call auction. Then let's analyze the risk-benefit ratio of participating in call auction and not participating in call auction. For the sake of intuition, we use the "two-price profiteering short-term trading system" in the first "time rule".
"Two-price profiteering short-term trading system" rules: when the price of copper, rubber, stock index, soybean oil and other varieties fluctuates sharply above the opening price, they will operate on the basis of the opening price, that is, buy short positions and sell multiple orders below the opening price. If the operation fails to make a profit for four times, close the position; If the operation is less than four times, hold and close the position (except for ups and downs).
(1) call auction immediately buys the buyer and clinches the deal. After the opening, the price rose slowly compared with the opening price 100 hops, and the income 100.
(2) call auction immediately buys a deal. After the opening, the price slowly dropped by 65,438+000 hops from the opening price, and when it dropped by 2 hops, the position was lightened, with a profit of 96.
(3) Bidding auction immediately buys the house and clinches a deal. After the opening, the price rose rapidly from the opening price 100, and the income 100.
(4) call auction immediately bought the buyer and made a deal. After the opening, the price dropped rapidly by 65,438+000 hops compared with the opening price. No deal was made when the price dropped by 2 jumps, and the income was-100.
(5) After the opening, the price began to rise slowly by 65,438+000 hops. It was bought and sold when it rose by 2 jumps, and the yield was 98.
(6) After the opening, the price began to drop slowly by 65,438+000 hops. When it fell by 2 jumps, it was sold and sold, and it was held still, with a yield of 98.
(7) After the opening, the price began to rise rapidly 100 hops. When the price rises by 2 jumps, the purchase fails and the income is 0.
(8) After the opening, the price began to drop rapidly 100 hops. When the price drops by 2 jumps, it is not sold, and the income is 0.
