After analyzing the 4-hour chart of crude oil, it is found that yesterday's market first fell and then rose, rebounding after reaching support near 78. In the short term, it has broken through resistance at 79 and 80 and now support has formed around 78 and 79. If there is a substantial breakthrough and stabilization around 81.5, there is a high probability of further rising towards the strong resistance level near 83. However, the market currently needs further consolidation and momentum to complete the potential breakthrough, so we recommend shorting at higher levels and going long at lower levels.
The specific recommendations are as follows:
short around 81-80, long around 79-78, with a stop loss of 70 points and a take profit of 200 points for each.
