Because green stands for active selling, the seller entrusts to sell at a price lower than the market price, and both parties take the initiative to clinch a deal.
In futures, red represents the market's rise and green represents the market's decline.
In many people's subconscious, red represents enthusiasm and excitement, and green represents silence.
Although the futures market can be traded in both directions, for most people, they still like to go up more and fall less, and they like to be long and short. Therefore, in the futures market, red, as a warm color, represents the market rise, while green, in sharp contrast, represents the market decline.
