Sudden surge but no volume's inducement reverse strategy

Prices suddenly spike, but trading volume does not keep up, and there are no significant large orders buying, which often indicates a false signal. The judgment method: a rapid increase of 3%-5%, but the trading volume does not exceed 80% of the average volume of the last 20 bars. This type of 'strong price, weak volume' is likely to pull back. The contract strategy is: to short lightly near the peak of the false signal, with a stop loss set above the high point of the long upper shadow. What you are capturing is the pullback after the false signal withdrawal.
