Short-term attention needs to be paid to 88000-89000 (4-hour middle rail coincides with the previous opening gap resistance)
Rebound to around 88000-89000 can be positioned for long, with a target of 85000-83000, and stop loss set above 90000.
If it falls below 83000, you can lightly buy back to below 82000

If it stabilizes at 85000 and MACD forms a bullish crossover at a low level, you can cautiously try to go long, with a target of 88000 and a stop loss at 84000.

Short at the rebound to around 2240-2270, with a target of $2100-2020, and a stop loss set above 2300.
If it falls below 2000, you can short to the 1950-1900 range.

If it stabilizes at $2150 and the 4-hour moving average turns upwards, you can take a small position to bet on a rebound to $2250, with a stop loss at $2100.
