Based on the current 15-minute structure, the market is in a clearly bearish dominant phase:

Prices have moved out of the standard downtrend channel of "higher lows and lower highs," with the short-term moving average (MA7) crossing below the medium-term moving average (MA30) to form a bearish alignment, and prices continuously trading below the moving averages, with obvious resistance on rebounds.

Currently, the downward momentum has weakened slightly, with minor stabilization and recovery at lower levels, but key moving average resistance has not been broken, nor has an effective reversal structure formed. The current oscillation is only seen as a weak rebound within the downtrend.

Suggestions:

1. The probability of shorting in line with the trend is significantly higher than going long against it. The key resistance zone (80520-80710) is a more reasonable area for observation and tentative short entries.

2. To go long, wait for the price to increase volume and break above the key moving averages, disrupting the downtrend structure. Currently, the signals do not support bottom-fishing operations.

The core of short-term trading is trend-following and risk control. At this stage, light positions following the trend with strict stop-losses, or waiting on the sidelines for clearer signals, are more rational choices.
