If you go to the stock exchange and wear a vest

Those who wear red vests are traders posted to the exchange by securities companies or investment institutions, also known as "market representatives". In the early days, there was no need for remote self-service For transactions, all customer trading instructions are reported to traders by phone, and traders type them into the exchange's trading host to complete the transaction.

In the stock exchange, front-line counter employees wear black vests, exchange traders wear red vests, and exchange managers wear yellow vests.

Red vests are traders of securities firms, and yellow vests are staff of exchanges. This design at the time was not in line with international practice. It was a red-yellow vest system with Chinese characteristics. In fact, the emergence of the red and yellow vests was a misunderstanding and coincidence. At that time, the colors of the Shanghai Stock Exchange hall were cool. If traders wore red, the colors of the entire market would be brighter and the atmosphere would be more energetic. As a result, when the comrade in charge of clothing went to buy cloth to make a vest, he saw that yellow was better than red, so he decided to buy yellow cloth without permission. But the yellow cloth did not meet the requirements, so I had to buy red cloth to make it again. By the time the exchange opened, several yellow vests had been made, so it was temporarily decided that exchange personnel would wear yellow vests. After a wrong purchase, in order to save raw materials, the later red and yellow vests were produced. Therefore, among the world's stock exchanges, only China has red and yellow vests.
