From the key signals of the 4-hour and 1-hour candlesticks in the chart:

1. Four-hour dimension (Chart 1): Strong support reached after a decline.

Bollinger Band signal: The price quickly fell from the previous high around 186, currently dropping to near the Bollinger Band lower band (LOW: 174.05), with the current price of 174.98 slightly above the lower band, indicating short-term support exists here.

Trend judgment: The previous upward trend from 155 to 186 has been broken, entering a short-term correction phase, but the validity of support near the lower band needs to be verified.

2. One-hour dimension (Chart 2): Weak rebound after a sharp drop, not yet reversed.

Downward momentum: The price has plummeted from around 186 to 173.34 (intraday low), with bearish strength being concentrated and released.

Rebound strength: A few small bullish candles appeared at low levels, but did not break through the 1-hour Bollinger Band mid-band (MID: 176.86), indicating a weak rebound and still a bearish trend.

3. Core conclusion: Short-term or 'weak rebound followed by continued bottoming'.

If the rebound is weak: If the price oscillates in the 175–177 range and cannot break through 177 (1-hour mid-band), it is likely to continue to test lower levels, examining support around 170 or even 160 (refer to the low of 155.72 at the end of July).

If there is a strong breakthrough: If the volume stabilizes above 177 and breaks through 180, it may trigger a corrective rebound, targeting the 185–190 range.

Operational ideas (for reference only)

Short-term traders: If the current price (around 175) is lightly long, stop loss below 173; if the rebound reaches around 177–180 and faces resistance, one can go short.

Long-term holders: Patiently wait for clearer reversal signals (such as a 4-hour close above the mid-band) before considering gradual positioning.

Market correlation reminder: The movement of SOL is greatly influenced by BTC and ETH, so it is necessary to pay attention to the overall market trends. If BTC breaks below 40,000, SOL may face further pressure.
