Newbie can note down btc 80,000-90,000 short-term swing trading:

82500-83800 is the first strong resistance area above 80k, this is a swing trading.

84000-85750 is the middle position, belonging to the second swing trading.

86300-87700 belongs to the third swing trading, which is a strong resistance zone before attacking 90k, generally experiencing repeated friction;

88200-88800 is a barrier before 90k, and a strong breakthrough will directly see 90k. If it cannot stabilize, this is a high point, and we should look to short towards 85000-81300.

After rebounding from below 79200 and breaking 80k, the first take profit position for low longs should be around 82500-83800. The first short position should be around 83800 because this is strong resistance and it won't stabilize immediately. Then it is right next to the 80k level, and after 80000 is broken, it becomes support, so this is a "short-term short." Generally, the short taken at 83800 can be closed for profit near 82555.
