Good morning There were also some operations yesterday, both profitable and unprofitable. It's all sesame and mung bean pork trotter rice. For example, yesterday afternoon's WCT 0.5 was okay. I looked at the announcement and found that if there was a pull-out opening at 5 pm, the OK spot price would definitely rise, so I chose to buy. There are actually quite a few opportunities to carve a boat and seek a sword here. In the past, UPIT prices were high, and Binance was able to pull it up as soon as possible, such as in the previous move. Not surprisingly, it rose near 5 o'clock, which resulted in a profit of eight or nine points. I chose to sell. Unfortunately, I became greedy again and saw that there was still a 5-point price difference. I bought it again and planned to sell it with Binance. Who knew it was OK card currency, but due to not shorting hedging in the first place, the profit was basically lost back. Because although there is a price difference between spot and contract, generally as long as the spot price falls, the contract will also fall. Afraid of losing even more, I took advantage of it. Those who don't have a set of bare bricks and still have card currency are the most unlucky, losing 5-15%. The best operation during the review is to directly buy spot at OK and then short, because at that time, the spot and contract prices of OK were very close, and you missed the opportunity to make a judgment. If you open at 5 o'clock to hedge and withdraw without rising, you will not suffer losses. After 5 o'clock, the spot price did not rise and directly leveled off. Selling the spot contract to close the position. If the judgment is correct, you can make a huge profit. For example, if you only dare to buy 10000 dollars for spot goods and bet 5 points that it will rise, but in the case of long short hedging only losing transaction fees, you may dare to buy 50000 dollars or 100000 dollars. I didn't do anything else, I was taking a nap when I went to UPIT. Most of the time, I still sit idle and watch TV dramas. Overall, it is still a state of continued waiting.
