Many people do not have a systematic process before placing an order.

Some people rely on a momentary feeling, some wait for the 'teacher' to call out trades, or follow a friend's suggestion, and immediately jump in. After the trade is over, very few people record the reasons or summarize their gains and losses.

When they lose, they say the market is unreasonable; when they gain, they attribute it to their good luck.

Over time, it seems like there is a lot of 'experience' on paper, but in reality, it is just going in circles over and over again....
