Short-term operation rules
Dare to buy varieties that are opened by huge volume after a sharp drop. When a huge drop is quickly opened by a large order, you should enter without hesitation. This is like watching fireworks in the night sky, first from red to green, and then soaring into the sky. Under huge volume, it can generally go from a sharp drop to a sharp rise, with a 20% gain on the day. The iron rule is the beautiful fireworks, which quickly become a passing cloud, and are immediately sold short at the next day's call auction.
Old coin friends have wisdom but no courage, and new coin friends have courage but no wisdom. When the turning point appears, only those who are both wise and brave, bold and careful can find opportunities and dare to buy and sell firmly, while most people often miss opportunities in hesitation, either missing out or riding a roller coaster.
