The trading ideas and logic during the day are temporarily as shown in the picture below:

10:30
There were basically no major issues with the empty direction yesterday and the excess longs on the left side. The long position near 3660-80 before going to bed is currently also at a profit of 140 points, and I have reminded to reduce the position. The subsequent situation is as shown in the figure below:
Currently, during the day, there is a rebound in the 1-4 hour period, with resistance above at 3890-3900 and a key position around 3965. If it does not stabilize above, there won't be much room for growth. Support below is at 3750-3660, so if there is a rebound during the day, I personally have a temporary bullish outlook. The reasoning and logic behind this is that yesterday indicated the possibility of a large range fluctuation in the 4-hour timeframe, which is also a probability. However, at least from the market perspective, it appears to be moving towards an upward rebound, and the 4-hour chart shows a bullish engulfing pattern after a decline. Therefore, I think going long today is safer than yesterday.
The long position strategy is as follows:
1. Buy on a pullback around 3750, set a stop loss below 3720 or around 3690 for additional purchases, stop loss at 3660, take profit at 3840-3950 (The stop loss and take profit range are reasonable, especially considering that after additional purchases, it won't hit the stop loss easily.)
2, near 3720 for the first position, add at 3670-80, stop loss just below 3660 + a little. Take profit at 3750-3840 (3750 is the take profit level after adding positions). The long position's risk-reward ratio is still acceptable above this level. The take profit position and target can be slightly lower, primarily aiming to exit, with flexibility in adjustments.
The short position strategy can be phased near the resistance level: enter a position at 3890, add around 3960, set a stop loss at 3975, and take profit at 3840-3750 and below. Overall, the daily chart is still bearish, and from a technical perspective, it hasn't reached the target. The reason for considering a long position during the day and reassessing in the evening is that we are currently in a rebound phase. Whether it can actually rebound is another matter, but the thought process is to anticipate a rebound. Additionally, the basis for entering at 3750 is that it may form a secondary head and shoulders bottom structure, focusing mainly on intraday movements, so for now, let's keep it that way.
Bitcoin's time levels are expanded and it moves differently than Ethereum. The preferred approach is to think about going short. The strong resistance above is at 111600+, which is also the stop loss level for short positions. The take profit level is still around 104400-102000 (the low point from October 10, to be reduced in batches). Bitcoin's volatility over a day is different, so with the same margin, Bitcoin only needs to enter once, the stop loss can be larger, and there is no need to add positions. The take profit can be done in batches to take advantage of the larger trend.
