According to my own trading experience,

Don't place an order easily: consider comprehensively before placing an order, one is the direction, and the other is the price.

Don't change direction easily after placing an order: many people are afraid of small losses after placing an order, so they cut off the order and the market will develop in the direction they expected. If the analysis is correct, they don't make money.

So before placing an order, set yourself a stop-loss and profit-taking price. Once in the order, don't run out easily.
