Firstly, it is necessary to establish a trading philosophy of low profits. In the short term, one should not be greedy. Set a reasonable profit margin for oneself, and be immediately eliminated when reaching the goal. Then, re evaluate the market and patiently wait for the next trading opportunity given by the market.
Thirdly, it is important to select trading opportunities that align with one's own trading principles and familiarity, and not engage in uncertain battles. Due to the thin profit margin, it is particularly important to rely on the success rate of selling to win the intraday ultra short term.
