In the morning, API data was bullish, and crude oil fell rapidly after a short-term rise due to the data. The output of crude oil in the international market continued to increase, but the sales volume declined, and crude oil entered the buyer's market. The Organization of Petroleum Exporting Countries has reduced its restrictions on oil-producing countries, and the output may rise again before the prospect of rising oil prices is difficult to see. Therefore, I believe EIA will play a key role in the trend of oil prices in the afternoon. If the market is bullish tonight, the oil price may fluctuate between 42 and 46 in the short term. If it is negative, continue to test 40 the first line.
