The support for SOL in the last three days has been around 252.85. If it breaks below this level, it will drop to 249.96 and 247.50, so this is also a low buy entry point. If it breaks below 250 for the first time, it will quickly recover to 254. As long as BTC doesn't turn downwards, there is no need to look too low.
Why has there been a rebound every time it has pulled back to 252 in the last three days, and both rebounds reached 264? Today's rebound only reached around 259.50 because it is Sunday, so we cannot determine if it is truly weakening. 252 is the middle band of the 4-hour Bollinger Bands for SOL, and when the K-line reaches this level, the 30-minute level initiates a rebound, so the support here is strong, especially since it is the gateway to the 250 round number, which will not be easily broken. Therefore, every time it pulls back to this level, one can buy. Now someone might ask, why is it certain that it won't break below this level? What will happen if it does?
The core issue is not whether it will break below, but rather your thought process: what happens if it doesn't break, what happens if it does, how to defend, whether to take a loss or reduce the position, how much to reduce, where to buy back after reducing, and where to take profits after a rebound. These must be very well practiced to do short-term contracts effectively. Whether a certain support level will break or not, one must plan for a potential break, and buy low near the next support level, that is, if 252 breaks, place orders to buy back at 249-247, and it will recover back to 254 after a rebound. Currently, it is all hourly level pullbacks, and the pullback range is very limited. If it is uncertain whether it will continue to rise, one should first take profits on part of the unrealized gains. If the BTC market needs to adjust, SOL can continue to buy back at 247-244.
