It's not to mention that the currency circle formula is quite useful
In the morning, you can add positions if the market drops sharply, and reduce positions if the market rises sharply in the morning.
Only reduce positions if the market rises sharply in the afternoon, and buy the next day if the market drops sharply in the afternoon.
Don't sell coins if the market drops in the morning, and add positions T+0 when the market drops.
Don't chase the rise in the afternoon, and reduce positions T+1 when the market rises.
Look at 10 points if the market rises in the morning, and look at 2 points if the market rises in the afternoon. Sell at the highest point. If the coin is strong, it will be closed at 10 points. If the coin is not strong, it will be closed at 2 points. Control the position and don't take chances. Rolling operation is the best strategy.
Don't short in a bull market, and don't go long in a bear market.
Don't sell at a loss in a bull market, and don't chase the rise in a bear market.
